Audiopipe TXX-BDD4-12 12" Quad-Stack Subwoofer — 2400 Watts Peak / 1200 Watts RMS, Paper+Fiberglass Cone, Air Cushion Foam, Multi-Connect, 2 × 4 Ohms

Built for deep, high-output bass, the Audiopipe TXX-BDD4-12 is a 12" quad-stack subwoofer centered on four 220 oz magnets to deliver massive handling and punch. Peak power is 2400 Watts with a continuous RMS rating of 1200 Watts, covering a frequency range of 28–1,200Hz with 86dB sensitivity. The cone is a paper + fiberglass composite designed to produce precise low end while improving durability under heavy loads. An air cushion foam surround increases excursion capability and enhances bass clarity for cleaner, louder output. Reinforcement comes from a quad-stitched surround finished with blue stitching to extend longevity. Power handling and thermal stability are improved by a 3" 4-layer black aluminum (BASV) dual voice coil. The driver rides in a black powder-coated die cast aluminum basket that protects against heat, minimizes resonance, and preserves structural integrity. Flexible wiring is supported via multi-connect terminals, allowing parallel or series subwoofer configurations. Mounting depth is 7-7/8" (200mm). Impedance is specified as 2 × 4 Ohms.
