5512-44

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.

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

pounding!!!!!

The following review is for a previous version (T5512-44).

i recently orderd these about 2 weeks ago now. all ican say is WOW. i have a 1990 chevy beretta z-26 so the seats fold down. And these subwoofers are a perfect match. they are hooked up to a audiobahn a8002t. so the amp is actually too big but just turn the gain down. these things pound. my buddy thought i had like 2 15'S but i only got MTX THUNDER 5500. GREAT BUY . if u want darn good subs for little cash get these u will not be dissapointed.

wow

The following review is for a previous version (T5512-44).

I heard one of these in a ported MTX box..and wow i was impressed. I'd highly recommend these. Spend the extra money over the 4500s. This one sub shook the car a great amount. I was impressed by the bass it put out. It was very smooth.

Great Subs!

The following review is for a previous version (T5512-44).

I have these in my 00' civic. They are extremely loud. They are hooked up to the MTX TA5601 amp and they are clear and very loud. These are amazing subs made by the best manufacturer in the business. I highly recommend these subs anyday.

AMAZING SUBS !!!!!!

The following review is for a previous version (T5512-44).

MTX is one of the best manufacturers for subs !! I got 2 of these 12" subs in a 1999 Jeep Grand Cherokee in a thunder box ported box running off only a 1000 Watt GPV Crunch Amp that puts out only 250 watts RMS and this is too loud! i had it for not even a full week and i got cussed at and yelled at 6 times for having it up to loud and shaking peoples houses going down residential streets!! if they are complaining now wait until i get a stronger AMP !!!! Product is unbelievable these subs hit harder then my brothers JL Audio subs!

AWESOME SUB!!!

The following review is for a previous version (T5512-44).

First off this sub is amazing. I bought it to put in my 94 regular cab Silverado. The ONLY bad thing is that its a bit bulky. Im right at 6' tall and i had to move my seat up a few notches, but im still comfortable. Anyways the power is pretty amazing. At my school we had a car and sound competition and most of the people had multiple subs. I only have this one and scored 4th place with 135 decibles. When i have it loud people look around like what is that? Great sub all around!

amazing

The following review is for a previous version (T5512-44).

these subs are incredible. i put them into my '97 ford escort running off an amp that only puts out 75w to each sub and they still push harder than a lot of higher RMS subs I've seen. if you run them to capacity (300w RMS) on a 600w amp they'll blow your eardrums. probably the most gratifying purchase you'll ever make

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.
