Enormous woofer equals mammoth bass. That's the equation behind the MTX Thunder7500 12" subwoofer, and boy, does it ever add up! Checking in at more than 20 pounds of of bass-pumping fury, this "superwoofer" sports a mica-filled polypropylene cone, a diecast aluminum frame, a solid steel pole piece, and a large poly cone dustcap for high performance.

The oversized 2" aluminum voice coil handles lots of power. Spider Plateau Venting dissipates heat quickly to minimize distortion. The post terminals accept up to 8-gauge speaker wire. Choose a sealed box for accuracy or a ported box for "boom" — either way, this sub will pound hard.
