The MTX Audio 55 Series subwoofers are the perfect solution for improving your car sound quality while taking up little space. Their low profile means they do not need a large enclosure and will still deliver powerful bass. How do they do this? With an improved surround compared to traditional Half-Roll surrounds, expanded surface area and reduced distortion due to progressive suspension controls. With over 40 years of audio experience, MTX Audio makes sure and knows how to create quality audio with their products, and the 55 Series is no exception!

The MTX Inverted Apex Surround increases the surface area of the sub to allow for more air movement, accurate bass reproduction and higher SPL. Traditional Half-Roll Surrounds have an inherent wrinkling when reproducing bass due to the physics of its motion, which causes distortion. The Inverted Apex Surround moves symmetrically through both positive and negative cycles which eliminates this type of distortion.
Progressive Suspension control the excursion of the subwoofer at high power levels which reduces distortion. Eliminating this 3rd order distortion means you can play your music loud and rely on your subwoofer to take of itself.
Two features really make sure the MTX subwoofers stay cool: the Spider Plateau Venting and the Radial Ribbed T-Yoke. The Spider Plateau Venting is a mechanical cooling process that targets cool air at the voice coil. This means the subwoofer cools itself as it is playing. The Radial Ribbed T-Yoke acts as a heat sink that dissipates heat and decreases distortion.

Excellent subwoofer.
I purchased this woofer about six months ago and installed in a sealed enclosure for use in the trunk of a 2014 Mustang. I am running it as the 5th channel off of an MB Quart 1100.5 amp. With this configuration, it provides more than adequate bass. You can "feel" the bass with this woofer; it has good punch and produces crisp, clean low frequency sound. Seems perfect for my application - probably the most bass my car could handle without needing Dynamat. Easy 5/5.

bring on the boom boom
I was very skeptical on a 15 because I listen to all types of music with a lot of rock thrown in. With this mtx in my ground shaker box it sounds fantastic with any type of music. Looks bad ass and with everyone in the area on a kicker/alpine kick it's fun to let them envy the odd one out. Bless everyone else's system out of the water

Wasn't expecting that.
I've always liked MTX but for some reason never liked the design of this one. I thought the surround was tiny and the cone just looked weak ????. Anyway customer brought his mini Cooper in for custom box. Long story short I built the box to 2.32 net tuned it @ 35 Hz with L port. I'm not Guna lie this thing sounded sooooo clean, crisp, and LOW!!! I literally could not believe it. (????or I'm just an amazing box builder haha). Anyway the sub handled the MTX thunder 500.1 power very well and is still bumping 8 months later w no problems. Recommend both sealed or ported to b on the big side of recommended air volume at at least 200-400 watts.
