MTX Audio Thunder 7500 sub woofer

The speaker sounds phenomenal, in perfect working condition. Can easily test with my amp I have installed. I'll consider trades. ****About the MTX T7510-44**** 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 T7510-44 10" 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.
