So it seems our crew is really serious about taking this ACE down to the frame. It looks like all the parts have gotten a sealer coat, an army green primer coat, and hopefully a finishing coat in the not too distant future. Looks like Heidi added a Polaris 2500HD winch to the front and as you can see they have taken this pristine machine down the bones in order to resurrect it to the next level as a serious offroad AND audio machine. Can't wait to see when they start putting it back together.
So if you don't know, MTX and Polaris, manufacturer of awesome off roading machines, like to get together and build some crazy things. If you haven't seen the RZR1000 Ground Pounder our boys put together last year for Polaris you are missing a serious piece of offroad terror. Polaris has recently released their new Sportsman ACE single passenger 4-wheel machine, similar to the RZR Series just smaller and with room for only one. Well I happened by our R&D department the other day and saw that our team somehow had gotten ahold of one of these machines and are working on turning it into an audio beast to match the Ground Pounder. As I understand it, they are going to be adding a custom fiberglass roof with four 7.7" marine speakers, a fiberglass hood unit that houses two 6.5" marine speakers, and an amp rack that is going to live on the rear cage. We are going to be taking both the RZR1000 and ACE to the ATV Mud Nationals in Jacksonville, TX March 26th-30th and showing them off with Polaris.
I was watching UFC reruns the other day on FX and they were replaying this fight. This was the first fight for female UFC fighters on primetime TV and it introduced the world to Gina Carano. Kaitlin Young represented MTX like a warrior. What a great night that was, I am still sorry she lost!
Our new 95 Series SuperWoofers will be available in the second quarter of 2014! This new series is designed with premium aesthetics and innovative engineering that outclass all other subwoofers.
True to its heritage the performance of the new 95 is going to shock a lot of people. It can make the windows flex for those that like it loud and reproduces every bass drum slam and guitar stroke flawlessly even at amazing SPL levels.
The new 95 Series car Subwoofer will be available in both 12" and 15 sizes and with either a dual 4Ω or dual 2Ω voice coil configuration. Each model is capable of handling 1500 watts RMS power.
The 95 Series features the Inverted Apex Surround that we released in 2013 on the 55 and 35 series woofers. This surround increases xmax, 1.25" on both models, and surface diameter allowing it to produce impressive competition level bass.
A 4" high temperature voice coil is cooled using our proven spider plateau venting technology as well as an internal voice coil heatsink and a t-yoke with integrated heatsink, giving it a three-layer thermal management system.
Our engineers have also incorporated a layered, progressive spider that eliminates the break in period that subwoofers normally require.
Out of the box these subs are ready to deliver the boom. Finally a glass fiber cone offers excellent stiffness to weight ratio-increasing efficiency for greater SPL.
The 95 Superwoofer will be available 2nd quarter, 2014. We can't wait!
Most car subwoofer enthusiasts start shopping for their new system once they have decided on the quantity and size of subwoofers they want to buy. After all, subs are the main part of the system that creates the window rattling, body-panel-flexing bass they crave!
But a common mistake when choosing subwoofers is that the higher the power handling rating, the louder it will sound. This assumption is perfectly logical, but not always true.
To understand this tradeoff, you need to know what makes a subwoofer loud (SPL) and some basic physics. Now, don’t expect this post to be a science lesson with a bunch of technical equations and diagrams. This is a basic explanation of SPL and subwoofer power handling.
First, some definitions you need to know:
As a disclaimer, remember that a manufacturer can put any incredible number they want for their "Peak" or "Max" power ratings and many manufacturers do this as a marketing tactic to get customers to believe their product will be louder, better, more powerful, etc… You can't cheat physics; anyone afraid to publish their data is probably not being 100% honest about their ratings.
Sound is created by vibration of an object. The vibrating object causes air molecules nearby to move in waves. The more air molecules that are moving, the louder the sound waves will be. As the number of air molecules moving within the interior cabin of your vehicle increases the air pressure increases. This is called sound pressure. The Sound Pressure Level (SPL) is the measurement of this pressure in decibels (dB).
So in the simplest terms, the more air you move, the more SPL will be generated. So go buy a bunch of 18” woofers and you will be loud. Right? Not necessarily. There are other factors to consider. An 18” woofer has a lot of surface area to move air molecules, but can the woofer move a lot of air? This is where Xmax comes in. If the 18” woofer can only move 1/16th of an inch, it’s not going to move much air and therefore will not be very loud.
Well… A lot of engineering! It takes a good suspension (spider) that can handle the movement while maintaining linear motion. If a subwoofer does not stay linear, it will create distortion, or worse cause a rub or short of the voice coil against the pole piece causing damage to the subwoofer. A quality suspension is very important.
Additionally, you need a strong magnetic field which uses AC current to push the woofer forward (positive) and pull the woofer backward (negative). This magnetic field is created by the interaction of the magnets on the woofer’s motor structure and the electrical current being transferred through the voice coil from your amplifier.
At this point many people get caught, logic would tell you the bigger the magnet, the bigger the magnetic field. The more power through the voice coil, the more Xmax the subwoofer will have. The more Xmax you have, the louder the subwoofer will be. Right? Not necessarily.
You could build a subwoofer with HUGE magnets weighing 200lbs each and a voice coil that is capable of handling 10,000 watts. That’s easy. But designing a suspension that can keep that power under control is the hard part. If the suspension is too tight and rigid to control the power, it will limit the Xmax.
Mass is another factor that must be considered. Subwoofer A has a RMS power rating of 2,000 watts and includes huge magnets with a cone assembly made of aluminum that has a mass twice that of the cone assembly of Subwoofer B which has a RMS power rating of 500 watts with magnets half the size. Which subwoofer has the potential to be louder? This is in fact a trick question.
You can’t determine which subwoofer would be louder simply from this information. Subwoofer A can handle more power but it’s cone assembly is heavier and therefore it requires more power to move it. Xmax could suffer as a result. Subwoofer B can’t handle as much power but it’s cone assembly is lighter and therefore, it’s Xmax could be as good or better than Subwoofer A, thus moving more air. This is called efficiency or sensitivity and is rated in decibels (dB) and should always be measured at (1W/1m). After all, you don’t want to spend the extra money for a HUGE amp or tax your vehicle’s electrical system to power it, right?
As you can see, comparing the performance of car subwoofers purely based on the power rating is not a fair comparison. There are many other factors to consider.
And once you start the installation, consider enclosure design, speaker wire size, and power wire gauge to ensure your subwoofers perform to maximum potential. If you buy a subwoofer with an RMS power handling rating of 2,000 watts, put 2,000 watts to it. Under powering a subwoofer is often times worse for it than over powering. Also make sure your vehicles electrical system can support a 2,000 watt amplifier. And remember a 2,000-watt amplifier (that truly produces 2,000 watts RMS) will generally cost you more than one rated at 500 watts.
So if you are in the market for a subwoofer, don’t be fooled by peak power ratings created by crazy math. These numbers don’t mean much. RMS Power ratings are what you want to notice. This spec doesn’t always reflect performance either, but I will leave this discussion for another article.

Second day is coming to a close at this year's CES show. I like coming to the show because we get to see a lot of our industry friends and we get to show them our latest cool products.
The new 95 series woofer, https://www.mtx.com/95-series, is getting a lot of attention. I can't wait until our master installers get to put something together with those new woofers to show how incredible they really are. Keep an eye out for some head to head videos in the near future that showcase how they hold up against other subs.
The new MUD amp has also been a big hit. That bad boy is really small, delivers great power, and is weatherproof. Install it anywhere and take your sound with you. Coolest thing about it is all the connections are made through a Molex pigtail making it extremely easy to install.
Happy New Year to MTX fans around the world. This is going to be an exciting year at MTX. You may notice that our website looks different than it did last year. We have changed some systems and added some features designed to make MTX.com a destination, not just a place to buy high quality audio. Take a tour of our eduction section and improve your knowledge base also visit our Community section and take an active part in helping and getting help from us and your fellow enthusiasts. As always if there is info you would like to see, give us a shout.
The International Consumer Electronics show is coming up next week and we are getting ready to unveil some really cool new products that our engineers have been hard at work putting together. The biggest news this year is going to be the release of the new 95 Series car subwoofer. True to its heritage the new 95 is going to shock a lot of people. A couple of highlights for the new version:
This sub is going to rattle some windows. For all those people that said MTX isn't what it once was I think this sub will change your mind. It is designed for SPL plain and simple. This year we are also going to be releasing a new 75 series subwoofer that utilizes some of the same technologies that are in the 95 but in a less lethal version.
New XTHUNDER amps will be available in early Spring. 1500W and 1200W class D monoblocks that are 1Ω stable, a big four channel that puts out 125W RMS, and a convenient five channel ensure there is something for eveyone. Cool thing about these is that they all share the same footprint so they are easy to do custom installations with and all the wires and controls are covered by endcaps allowing for really clean installations.
We are also releasing some new marine product at the CES show. Three new amplifiers, two subwoofers, and two sizes of coaxial speakers that are built to last. We test them in the Arizona sun and in the Wisconsin winter, so they have seen their share of environmental abuse. The amps are all small chassis so they are easy to hide in any size boat and the subs and speakers have an agressive look that compliments any boat interior.
Check back with us to see pics from the show and to learn about the new stuff we have coming out and what else we are up to.
