Up for sale is my MTX 7500 ( T7515-44 )
I ran this sub for about a year before purchasing new equipment
I used to install for a car audio shop so I can assure you this subwoofer was never abused or misused
This subwoofer is loud and should only be installed by a professional

Please email me if interested

MTX makes Thunder7500 subwoofers for the bass enthusiast who's looking for competition-level bass that won't cost a fortune. These serious subs sport durable mica-filled, polypropylene cones with stitched rubber surrounds for bass that's responsive and accurate.

The T7515-44 15" subwoofer rocks hard in both sealed and vented enclosures, and you can feed it up to 400 watts RMS for pulse-quickening low end. Its dual 4-ohm voice coils let you draw maximum power from a compatible low-impedance amplifier, and heavy-duty chrome push terminals allow for easy system connection.

MTX's unique linear drive system keeps the cone centered during extended travel for smooth bass with low distortion. The non-resonant aluminum frame provides ample venting to keep harmful heat away from the sub's inner workings.
