• User Manual

Big bass. Small space. Zero excuses.

The Audiopipe TXX-FB1200-S4 is built for systems where depth is limited but expectations aren't. At just 3.9 inches of mounting depth, this 12" shallow sub drops serious low-end punch into trucks, sedans, under-seat enclosures, and custom slim builds without sacrificing output or control.

Powered by a 3-inch high-temperature 4-layer BASV voice coil and backed by a 65 oz magnet, this subwoofer handles real power confidently at 400 watts RMS. The non-pressed textured paper cone and foam surround keep bass tight, musical, and distortion-controlled, while the rigid powder-coated aluminum basket keeps everything stable under pressure.

This isn't a "budget shallow." It's a slim powerhouse built to hit clean and hit hard.
