Description

5512-22

The 55 Series, MTX's best selling subwoofer family, is a perfect mix of performance and value for enthusiasts that want to add extreme bass to their system without breaking the bank. MTX have squeezed an oversized cone into the standard 10", 12" and 15" frames, so the sub moves more air and gives you more bass. The woofer's movement cools the sub as it plays, so it doesn't overheat when you're rocking out. The special suspension exerts extra control when you're pushing the sub hard.

This subwoofer features the MTX Inverted Apex Surround. This is a departure from a traditional half roll surround. The Inverted Apex is narrower thereby increasing the surface diameter of the subwoofer cone enabling it to displace more air and generate higher SPL. The 55's are designed with a progressive suspension that lowers distortion resulting in improved sound quality even at high volume.

This subwoofer also incorporates Spider Plateau Venting which is a mechanical cooling process that targets cool air at the voice coil and a radial ribbed t-yoke that acts as a heat sink effectively managing the subwoofer temperature for long term rocking performance.

Great Sub

This is a great little subwoofer for the price. I say little, but it isn't. This 12, in a ground shaker box in my 2012 Kia Rio hits hard. Well worth it, and easy to set up. Would recommend.

Didn't work out

I bought this because I had mtx subs before that lasted a while. I really liked the look of these when they came out with the red stitching. I wired this to a 1 ohm load and ran it to a Fosgate 5001bd amp in a single ported box. This sub didn't last one day before it smelled like it was burning up. I sent it back and Sonicelectronix issued me a refund. I replaced it with a Massive Kilo. That thing rocks!
