“Designed from the ground up to be the most weighty subwoofer ever, Jackhammerincorporates radical new technologies. It is even manufactured in MTX’s tradition facility with a magnetizer constructed just for this woofer-a magnetizer that wipes out any credit card that dares come inside 25 feet! JackHammer is the Biggest, Baddest, Boldest subwoofer…ever!”

Billed as the subwoofer that “other woofers have nightmares about,” the MTX JackHammer is a 2-foot tall, 369-pound behemoth that makes you haughty to be an American. This 22? subwoofer handles 5,000 watts RMS (up to 10,000 watts peak), and features a 900-ounce (that’s a little over 56 pounds, folks) magnet and a 6.5? voice coil. The JackHammer is set up for high SPL (Sound Pressure Level), but you can obtain an replacement cone assembly that allows you to switch swiftly to Sound Quality execution (and you don’t have to remove the speaker from its enclosure to make the switch). There was a constant squeeze around this woofer throughout the show, jaws open, staring in awe as the woofer cone moved in and out. Sometimes dismiss is a good thing!

The MTX Jackhammer is frequently used in sound force level competitions where the just real is sheer loudness. In fact, one Jackhammer is capable of high ample sound humiliation levels that staff who are close are often wearing ear protection. The Jackhammer is able to create sound force levels high amply to easily damage human earshot. It has been measured at well over 150 decibels, which is 30 decibels more than an airplane at takeoff. The Jackhammer consumes much more power than the mean electrical system of a car can provide, adding to its impracticality. It usually requires multiple strong bridged amplifiers to drive it, and high quality wires are needed to carry the tendency to the speaker. Multiple colossal capacitors are also mainly used. About four lead automobile batteries are required to power the amplifiers. Between the subwoofer and everything needed to power it, the system weighs well over 500 pounds (230 kg).

From Business Week’s report from the Consumer Electronics Show: “Tricked-out cars are a growing phenomena, thankfulness in part to Pimp My Ride. The familiar MTV’s reality show gives twenty-somethings a change for their old beaters, getting as much as $30,000 of new supersonic audio and video gear on a rigs goodness less than $1,000. So it’s no amaze that a star of the show, Mad Mike, is signing autographs at the booth of MTX Audio, which makes car speakers, amplifiers, and subwoofers.

Mike is portion MTX push its JackHammer subwoofer, a 369-pound, 22-inch high throbbing hunk of sonic goodness. One recent Pimp My Ride episode featured Mike and crew putting the JackHammer in a 1986 Buick Regal. The crew added a flashing carefulness light on the center panel of the car that reads “Warning: Ridiculous Bass” whenever the stereo plays.

So does anybody certainly need that much bass? “Absolutely,” says MTX’s ever-dutiful spokeswoman Hilary Moore. “Everyone needs a JackHammer.” Since the $7,500 unit pumps out the equivalent of a dozen 12-inch subwoofers, Moore rationalizes that the JackHammer actually saves space

The initial beloved products by them were the PowerWedges, which were the firstly enclosed speaker systems convenient at the time. PowerWedges are famous for being compact yet providing some of the newest technologies for the time. The 8W2 woofer was released to be used with the PowerWedges. Being flourishing as an 8-inch woofer, the 8W2 was also released in 10-inch and 12-inch versions, both just as prosperous.

JL Audio that time released the W5 speakers series in 1987. This series was built on the premise that speakers could be much more forceful than they were at the time, and the W5 line definitely raised the bar on forthcoming products. These speakers replaced the older ones that failed to give strong sound that maintained a certain level of quality. JL Audio could barely keep up with their orders pending this period, demonstrating just how innovative this guest was in developing advancements in the car audio industry.

The next industrious JL Audio line was the W6 series. This time, the associates focused on improving sound feature. Obviously, the W6 line was able to do so, because it was received very well in the market. However, it appears that this JL Audio series demonstrates a frail problem, as volume now becomes an issue. Regardless, the new innovations packaged as the W6 series have now also appeared in many other products released by other companies.

Considered the most technologically precocious and top of the line in the JL Audio arsenal, the W7 series introduces six new technologies bound to pack more power into the subwoofers. It’s no wonder, since compared to the other products, like the W5 and W6 series, the W7 series is totally different. JL Audio built a subwoofer from scratch rather than reform on an existing one. These speakers implement the two most considerations: volume and sound quality. While the W5 focused on improving volume, and the W6 on quality, the W7 focuses on both.

As you can see, JL Audio’s 35 years of endure materialize in the innovations of their speakers. Their products have consistently been the best of the best, and there’s no doubt that their forthcoming products will go along to do so.

The 8-inch version has drawn numerous positive reviews from car audio experts and foremost organizations. Car Sound and Performance calls it the “best damn 8-inch subwoofer ever made”. It’s small, yet powerful, and the 8-inch subwoofer has not ever been made so well in so long. It’s actually no doubt that it’s getting rave reviews. JL Audio has definitely taken preference of the situation and brought the little ones to own the bigger ones.

It is reported that this 8-inch version almost didn’t make it to the final lineup. The 21st century is reasoning that bigger is definitely better, but that’s not the case here. The smallest version, a size unusually seen in the lines of other companies, has undoubted to be just as potent as the other, more approved sizes. While the contention is racing to see how big it can make subwoofers sans losing power and quality, They suddenly dropped a smaller size, which broke the stereotype that smaller subwoofers won’t do much good at all.

A letters to the editor that seems insignificant at first, the owner’s manual is truly quite important when it comes down to the actual installation and optimization of the JL Audio 8W7. Many consider it’s owner’s manual one of the best, because it not barely includes the standard enclosure recommendations and specifications, but also includes recommended amplifiers to match up with the 8W7 and tips to get the best out of the system throughout tweaking lacking busting it.

Overall, if you want to downsize from a 10-inch or 12-inch subwoofer, or want to try something different that’s hard to find on the market, the JL Audio 8W7 is a nice place to start. It takes everything citizen love about the 10 and 12 inch pieces, upgrades it, and repackages it as an 8 inch. Seriously, if you want portion that’s even more powerful than many other subwoofers on the market, you’ll want to choose the W7 line. But if you want something that’s compact and does the same, you’ll want to select the 8W7.

Custom Fiberglass Subwoofer Box:

Materials:

1 Gallon of Fiberglass Resin (find at Auto Zone, Advanced Auto Parts, Etc)

Cheap Paint Brushes (probably about 10; you will throw off after each use)

Rubber Gloves for fiberglassing

Fiberglass mat (about 6-8 packages depending on the size of your box)

MDF Wood 1/2?

2 Dowel Rods

2 Rolls of Masking Tape

Aluminum Foil

Cheap Mixing Cups

1-2 sq yards of fleece (hobby lobby)

Fiberglass Sub Box:

Ok, time to start constructing a fiberglass sub box! The earliest step to forming the box is drawing out some plans on what you want and how to you want to do it. When fiberglassing, you can’t actually fix your mistakes because when fiberglass resin is dry, its DRY.

We wanted to make a common box that would save space, and look oem to the prelude. We started by laying masking tape down so no fiberglass resin gets on the carpet, because if it does, its ruined. Also, make sure to tape extra space therefore your actually leave-taking to use just to be safe.

We did about 2-3 layers of tape and in addition also added some aluminum foil as a layer, as to not get any glass on the carpet. When you recall that you have enough tape and there is no probable way that now fiberglass could get by way of to the carpet; do another layer.

The next step after you have tapped everything is to start fiberglassing. Before you mix your fiberglass with your hardener, you should cut strips out of your fiberglass mat. I usually make strips about 7-9 inches wide. When you are ready, what you need to do is mix your fiberglass with your hardener in the mixing cup. The hardener will have how much fiberglass resin to hardener mix to make. Make sure you get ready in front of you start fiberglassing since it dries somewhat quick. Paint a layer of fiberglass resin onto the tape outdoors any mat. After you’ve painted a layer put fiberglass mat down and paint another layer over fiberglass after that. Wait about 10 minutes and furthermore do another layer previous to it dries wholly.

Now, halt at least an hour and let the fiberglass resin entirely dry. When its dry, you can take the mold out and tear off all the tape and aluminum foil. Put it back in your trunk and draw out where you want to cut off. Make sure you go gradually and don’t take all of it off at once.

Now you need to cut out a MDF ring for your subwoofer to screw into. Some favor to make a flush ring with a router but I like the one ring way well. I am using a 10 inch jl audio w3 so I cut out a 10 inch ring and used the specs from the box to make a ring the right size.

Then we pulled out our lately trimmed fiberglass box and put another layer of fiberglass mat on it. Generally you want to do about 5-6 layers of fiberglass. Some say you should be able to stand on your box without it breaking. Another good fiberglassing tip is to remove as many air bubbles as likely. This will make the mold a lot stronger since there’s no air pockets. You do this by jabbing the fiberglass rather than actually trying to paint it.

Ok, ample playing around; back to fiberglassing! Next we put on a last layer of fiberglass mat and resin. After this has totally dried (about 3 hours) we started sanding and cutting to get the shape we wanted with our tradition fiberglass sub box.

Once your back mold looks good to you its time to set your MDF ring up how to want your sub to be. Hold your ring up where you intend you would like it. Cut some dowel rods to size and condition your ring how you want it. We used superglue and epoxy to keep the dowel rods and the MDF ring in place. Its important that your ring is very strong and firm because we are going to stretch fleece over it.

Make sure that when your ring is in place every angle looks good and even to you. When you stretch the fiberglass and start painting resin on it, there’s no turning back.

Now is the fun part. This is where your fiberglass subwoofer box starts to come together. Grab your fleece and stretch it over your mold you have made. Be sure to stretch it as tight as plausible so there are no folds or loose parts. The fleece should be touching every edge of the back of the fiberglass mold.

Use a staple gun to content the fleece to the subwoofer fiberglass mold. Staple the staples in the side of the fiberglass box so you don’t fiberglass over them and have them be stuck forever.

Once you mean its done look it over again from all side and make sure it looks how you want it to look since once the fiberglass resin is on, its that shape forever.

When everything looks good to go, its time to start glassing. Mix a good add up to of fiberglass (about 12 oz) and paint the fiberglass over the fleece. Paint it on thick, and make sure to go all the way to the edge so you mold the two pieces (front and back) together. There’s no need to paint the complete ring since we are departure to cut it out anyway. Do fiberglass the fleece to the MDF ring.

Once its dry (took about an hour because we used a lot of glass) you can cut off the enter fleece from the edge of the mold and around the ring. At this time you should be able to pull the dowel rods out of the box and the ring should sojourn where it is. Once you’ve trimmed off the bulk dismiss of the fleece, throw the box in your car and see how it looks. Looks pretty good here!

Not to mess up the external shape of our fiberglass sub box, we need to add the rest of our fiberglass layers to the inside of the box. Add about 2-3 layers of fiberglass mat to the inside of the mold. Make sure to fiberglass in between where the two molds came together.

Once you texture the inside of the box get out the sander and the jig saw and cut off all the excess crap around your fiberglass box. We are going to use carpet on our box, so we do not need to sand the really fiberglass mold. Instead we just sand all the corners and edges so it fits snug into the trunk of the Honda Prelude.

For aesthetics and some extra concentration (since JL subwoofers are so loud) we added two more layers of the carbon fiber style fiberglass mat. This will ensure concentration and reliability.

After this step, you are done! Just pop your subwoofer in there and make a tiny hole for your speaker wire. If you are too add carpet, you can do the same as you did with the fleece and stretch it around your mold. If you are lacking to paint your tradition fiberglass subwoofer box, you will need to get some bondo and a lot of sand paper to level out the fiberglass sub mold.

For many first time car enthusiasts, it was that deep bass and pounding rhythms which firstly drew them in. Unfortunately, factory installed OEM speakers just dont cut it. If you want real, character sound, you will need to shop around for a subwoofer.

Adding an aftermarket subwoofer can result some massive results. Just adding one or more to your cars audio system can give you the single, most significant sonic improvement likely just by adding some substantial bass to your music. Here are a few points to reconsider before purchasing a new subwoofer system.

* The initial thing youll need to do is decide where you want to install it in your car. Normally, they are put in your trunk, but a little modification, subwoofers can be put almost everywhere in your car.
* Now that you know where you are departure to put it in your car and an opinion of about how big of a size you are looking at, decide on how much you are willing to spend. You will be spending at least $300 for one plus installation, so its best to set a cost bounds.
* Do you want to use one or two? The answer to this question depends on what type of music you listen to and how much room you have in your car for two. If you listen to music like rock or country, in addition you can get absent with using barely one subwoofer but youre better off sound wise with installing two if rap, R&B, or techno fits your music savour.
* Pick a size you want. They are ordinarily found in sizes ranging from 8-inch, 10-inch, 12-inch and 15-inch with the larger ones producing the berth the frequency. Now that you know the size, make a detemination on what kind of enclosures the subwoofers are leave-taking in. These will play a factor in deciding the size as well.
* Sensitivity of the subwoofer needs to be taken into deliberation. The sensitivity is the rating of how much sound is generated for how much power is into the speaker. You regularly would look for a high number since higher is improve.
* Youll need to know the max wattage RMS power it can handle. The more power, the more sound that is produced. It will also be more expensive price wise, since you are going to also need an amplifier to deliver all that power.
* The concrete the cone is made of is a factor to consider. You have a prime of Kevlar, polypropylene, aluminum, or carbon fiber cone. Never ever buy one made from paper. Now that you have chosen the make of the cone, make a decision on the make of the surround. Rubber surrounds are the best and one made from foam work adequately. By choosing the complete match of materials for the cone and surround, you not lone reform sound but also longevity of the subwoofer.
* Of all the steps, this one is the easiest and probably the most enjoyable. Sit back and enjoy the sounds of your recently installed great sounds.

Sometimes all you need is the right speaker to enhance even the most general sound system. There are many terms that you have presumably heard tossed around in regards to speaker systems. Do not make the assumption that you have to have every one of the indicated components. If all you want is basic speakers, in addition you can suitable find some in a decent price range in your local auto parts store. It is frequently best to stay gone from the cheapest ones. Find a merry medium if you can and always read the details on the box earliest.

Many citizen want a bass booming sound that will fast turn heads as you drive by. That is rather relaxed to obtain. A sub woofer is used, frequently along with an amplifier to expand the yield of sound. The difference is noticeable right continuously when compared to speakers absent a sub woofer. Two ten inch sub woofers is frequently best for someone that is seeking sufficient sound lacking event that is over the top or contest level. Sub woofers do need a substantial total of power however since they have to move a lot of air to deliver the best sound.

When you select car speakers, you definitely want to pay close attention to the brand. Choosing a brand that is known for electronics and speaker components is best. It is simple to get sucked into buying something generic or unheard of just because it is chinchy in cost. That oftentimes means it is also stingy in attribute although and it is promising best left avoided. Stick with a brand that you know you can trust. Even if it is not top of the line, it needs to be anything that you feel cheerful investing your time and money in.

If you want the biggest boom likely and appraise is not an issue to you, then there are many astounding rivalry level speakers and speaker components. They are frequently much higher in expense but are often goodness it in terms of potential and the clearness of the sound. Find a task that specializes in speaker sales. They will have staff that will be provided to answer all of your questions and explain details to you. The right set of car speakers can take your converyance to a whole new level of entertainment. Be sure to hold onto any receipts though, just in case.

Subwoofers are useful for augmenting main loudspeakers by providing playback of low bass frequencies at high levels. Subwoofers are usable in several formats, together with bass reflex, acoustic suspension, infinite baffle, horn loaded, tapped horn and bandpass types. The range of sounds from lowest to highest that the subwoofer is capable of reproducing is called frequency range. The actual frequency range can vary depending on the type of box, crossover point, and the medium the subwoofer is installed in.

All loudspeakers characteristically exhibit trade offs between frequency response and response time or transient reply depending on the characteristics of the voice coil, properties of the magnetic motor, the cone mass, and the character of the enclosure.

The voice coil consists of a bobbin with wire wound around it. The voice coil is attached to the bottom of the cone and extends into the air gap surrounding the pole piece. The voice coil translates the magnet’s energy into cone motion. Cone size and voice coil inductance are main factors for a subwoofer.

Subwoofers use drivers woofers regularly in the middle of 8″ and 18″ in diameter, but some have been as large as 60″. Some drivers as small as 4″ may be referred to as subwoofers but drivers less than 8″ generally have neither the cone area nor excursion capability needful to produce deep bass, particularly in practical sized enclosures. The most common subwoofer sizes in professional concert audio are 12″, 15″ and 18″.

A brief history

The earliest subwoofer was industrialized during the 1960s by Ken Kreisel. Kreisel’s solution was to design a powered loudspeaker that would reproduce simply those frequencies that were too low for the electrostatic speakers to convey and how fill in the lacking sonic information. Infinity’s full range electrostatic speaker system of about the same time also used a subwoofer to cover the berth frequency range the electrostatic arrays did not handle adequately. Subwoofers came into greater favorite attention in 1974.

Applications of subwoofers

Subwoofers are used in different systems. The main areas of request include professional audio, home audio, car audio and many other fields. Subwoofers are now almost universal in professional sound applications such as live concert sound, churches, nightclubs, and theme parks. Professional audio subwoofers must be capable of actual high output levels. This is reflected in the design attention given in contemporary years to the subwoofer applications for sound reinforcement, public address, and concert systems.

A subwoofer does not necessarily furnish archimandrite bass carrying out in collating to colossal conventional loudspeakers on ordinary music recordings due to the lack of extremely low frequency content on such sources. Most house and car systems have much smaller and unequaled drivers at low frequencies; they attempt to reproduce actual low frequencies with colossal cone motions.

The crossover filters of subwoofers filter out sound that is high on the frequency scale. The point where this takes place can be adjusted. Sounds on the low part of the frequency scale are mere long and it takes a lot of power for them to be heard. By using a subwoofer to filter low-frequency sound, the base in your automobile will sound a lot improve.

When you’re looking for a subwoofer, it’s important to decide ahead of time how much power you want. If you have a lot of room and you want a lot of base, that time you will want to acquirement a subwoofer that has powerful, built-in amplifiers. Also, it is important to note, that the bigger the driver is, the deeper the base will be. Therefore, you may want to go with subwoofer with around a 10 or 12 inch woofer cone.

Many subwoofers come with a single cone at that time moves back and forth to help create sound waves that are low-frequency. The woofer cone can be riding one of two ways. The at the beginning way is called, down firing and the second is called front firing. Subwoofer cones that are down firing are essentially on the bottom of the subwoofer cabinet. When they are front firing they are on the side of the cabinet. One of the indicated is not necessarily improve then the other. It’s just a argument of design and your own secluded try.

Another important part of subwoofers is the enclosure. This is substantially the cabinet where the speaker is placed. By changeable the design of the cabinet, you can influence how the subwoofer works and its’ production. There are a couple of types of enclosures. They are called acoustic abeyance and base reflects. Acoustic deferment enclosures are inside a box and help to proffer base feedback. The sound that you will get will be tight and accurate. However, it will take a more strong amplifier that time is required with the base reflects design. A base echo enclosure has a port, which helps to make the base bigger and more extended. Essentially all of port is, is a hole that allows some of the energy created from the woofer cone to come out. These types of enclosures use power better, but they’re not as accurate.

Subwoofers provide full, prosperous sound and a lot of base. If you have standing speakers, you may be happy with the base. However, if you want a little more power and a little more kick furthermore you may want to consider adding finer subwoofers. Also, if you are rational of using your stereo system for a house theater or you just want truly big sound, that time you may want to study getting or upgrading your subwoofers

Because car subwoofers are specialized reproducers, their design maximizes their capability for generating the lowest frequency. Therefore they will have cones that are balanced in such a way as to promote the most back and forth motion, called XMAX. Middle frequencies have smaller cones and less excursion, or cone travel. Tweeters have cones, domes, or diaphragms that may seem almost motionless. Even so, they can deliver sound in their frequency range that is just as strong as their larger siblings.

Car Subwoofer cones must move in and out with the longest possible extension since sound waves get longer as they get depress in frequency. Current technology provides us with firm cone materials like Polypropylene, Carbon and Polymer Laminates that conserve their shape under stress, resist moisture, and are very light. The cone works as a piston to compress and alternatively clear immense masses of air. To do this most effectively, the subwoofer must be connected to an amplifier that produces the high amplitude waveforms that can create this motion. Because such signals demand substantial electrical power behind them to control the cone movement, the highest power available is needed strictly for bass generation.

Most car subwoofers are housed in a box (enclosures) to achieve their maximum audio power.

Car sound systems are rated on the potential of their audio as well as their talent to impress. Some of the most extremely regarded motor vehicles in the world have the sound systems to match. Their striking abilities relate to the quality and range of their sound as well as their comfortable accessibility and extensive features. Here are two of the top ranking luxury car audio systems according to askmen.com

The Marc Levinson Reference Surround Sound Audio System in some of the Lexus LS Models is the fundamental in precision sound system engineering. With this sound system, you can listen the car in front of you see it. Some of its admirable specs include a total of 19 speakers, a total harmonic distortion of less that 0.1 % and 450 Watts. One of the systems highlights is the fact that it has a phenomenal range of 20 to 20,000 Hz – above the hearing range of some individuals.

A car that reigns topmost with one of the most precocious and exciting car sound systems is the Audi A8. This sleek means has all the bells and whistles and its car sound system is one of its highlights. Developed by the famous Bang and Olufson, this completes the executive package. The car sound system consists of 14 car speakers which include a bountiful 12 inch subwoofer, with its own car amplifiers. This system is not just a pretty face, as its produces close to 1,100 Watts. It is, however, also about showing off, and the Audi does not dishearten with its acoustic lens speakers that expand and sheathe as you spin your tunes.

If you feel that your car stereo is losing its tune, visit your nearest car audio system dealer this day and insist that they replace your tired car radio with a power plant sound system.
