Audiopipe 15in Quad Stack Subwoofer TXX-BDC-IV-15 - 2800W Peak, 1400W RMS, 2x4 ohms

Power and engineering

The Audiopipe 15 inch quad stack subwoofer TXX-BDC-IV-15 is built for serious bass with a four magnet design. Its ventilated 3.3 inch BASV voice coil helps manage heat during demanding passages, supporting clean, controlled response from 25 to 1000 Hz. This setup provides ample headroom under dynamic tracks without excessive distortion.

• Peak power 2800 watts with RMS 1400 watts
• Impedance 2 x 4 ohms for flexible amplifier wiring
• 250 oz magnet provides substantial cone movement for solid low end

The combination of a lightweight yet rigid cone and advanced cooling translates to sustained performance across a wide bass range, making it a strong candidate for high output car audio systems.

Build quality and durability

Durability and rigidity are central to its design. The aluminum basket, reinforced dust cap, and Kevlar fiber composite non-press cone work together to minimize flex and preserve sound accuracy under heavy load. Progressive engineering choices aim to maintain consistent performance over time.

• Kevlar fiber composite non-press cone enhances rigidity
• Powdered black aluminum basket supports heat dissipation
• Textured dust cap adds structural stability

With robust construction and reliable materials, this subwoofer is designed to withstand long listening sessions and varied driving conditions while preserving sonic integrity.

Connectivity and setup

Connectivity is designed for flexible installation. The patent pipe multi-connect terminals accept up to 8 gauge wire, enabling straightforward series or parallel wiring of the dual coils. A mounting depth of 225 mm accommodates a range of enclosure designs, from compact to more spacious builds.

• Patent pipe multi-connect terminals for easy wiring
• Supports up to 8 gauge speaker wire
• Mounting depth 225 mm for versatile installations

Practical use and expectations

In real world car audio applications, the TXX-BDC-IV-15 offers deep, controlled bass across a broad frequency span. Pair it with a capable amplifier and choose a sealed or tuned vented enclosure to achieve a well-balanced, dynamic low end without sacrificing clarity at higher volumes.
