Thunderous Bass Impact

The chill finally crawls from off of your spine. For a moment there are no words that can describe the gut-wrenching bass tones you just heard. The next moment, you can’t stop thinking of new ways to let the world know of your experience. You’ve just been exposed to an MTX Audio T9500 superwoofer, and you won’t soon forget the experience. These subwoofers are an industry standard for those looking to make bass tones once thought unheard stand out right in your face and make their presence known.

Boasting a rating of 1000 watts of true RMS power handling, these subwoofers can really handle some power! A 260oz. magnet allows the T9500 subwoofers for a full 4” of peak-to-peak excursion! This means with the Thunder 9500 you get a full 1” of Xmax. A 4” voice coil allows for some mean bass reproduction and can really help reproduce the gut-wrenching deep low bass that a lot of SPL competitors are after.

For the price of this single subwoofer, you can get two of the orion HCCA subs, which have a higher rms, more excursion and an overall louder sound.

I bought two of these and a thunder elite 4001d from a buddy of mine. I had to put them in my girlfriends Hyundai tiburon because my car was in the shop. They literally shook the hatch glass out. Great subs. Now have them in my civic hatch and the amp turned all the way up and its a massage every time I drive. :)

I didn't buy this woofer from Sonic, I got it as a gift after my friend dropped it and ripped the cone wich took me 5 minutes to repair anyways. This woofer is awesome my friend has a solo x 12" with a 2000w brutus amp and my truck sounds about the same with a 1000watt hifonics HFI. Ohhh and the difference from my built to specs box compared to his built to spec box its amazing how small the box the mtx requires and his takes up his whole trunk of his suv. I LOVE this woofer. I'm guessing it would take about 1400 rms with no problem.
