The Audiopipe TXX-BDC-III-12 is a 12-inch car subwoofer built for high output on modest power. It uses a dual 4-ohm voice coil, a triple-magnet motor rated at 900W RMS and 1800W peak, and a Kevlar fiber composite cone on a cast aluminum basket. Sensitivity is a high 93 dB, so it gets loud from smaller amplifiers. It suits bass-heavy builds in sealed or ported boxes where output matters more than subtlety; rivals in its class often offer similar power handling but fewer motor and cooling features at this level.

Owners treat it as a loud, affordable sub that takes abuse, but note it wants a big box and clean power. Few describe it as accurate.
The Audiopipe TXX-BDC-III-12 is a 12-inch car subwoofer with a dual 4-ohm voice coil. It is rated at 1800 watts peak and 900 watts RMS. It uses three magnets for power handling, and its voice coil has increased ventilation.
The cone is a Kevlar fiber composite non-press paper cone with a textured finish, designed for improved rigidity. The basket is aluminum with a black powder paint finish and a dust-proof heat sink. The dust cap is composite glass fiber. Woven tinsel leads run on each side of the subwoofer.
Patent pipe multi-connect terminals let you wire the subwoofer in either parallel or series.
