Deaf Bonce Apocalypse D-3515R D1/D2 | 15" Subwoofer

The Deaf Bonce Apocalypse D-3515R D1/D2 is a 15 inch Subwoofer built for extreme power handling and deep bass in demanding car audio installs, delivering 3500 W RMS (7000 W max) with flexible dual-impedance options for a wide range of amplifiers.

• Size: 15 inch — large diameter provides greater displacement for louder output and deeper bass in challenging enclosures.
• Voice coil size: 3.50 inch — bigger coil improves heat dissipation, supporting sustained high-power performance.
• Cone material: Carbon — high stiffness-to-weight ratio helps reduce distortion during heavy excursion.
• Magnet: Ferrite — robust magnetic structure that supports high power in a compact frame.
• Surround: Foam — preserves linear cone movement and helps regulate excursion under demanding bass signals.
• RMS Power handling: 3500 W — continuous power capability for steady, loud bass when paired with a capable amp.
• Max Power: 7000 W — peak handling for transient bass peaks without clipping to the driver within its limits.
• Impedance: 2+2 / 1+1 Ohm — dual-voice-coil configuration offers wiring options to optimize load and amplifier damping.
• SPL: 87.30 dB — sensitivity indicating how efficiently the driver converts power into audible output at a standard distance.
• Fs: 32 Hz — low-frequency resonance contributing to strong bass extension in appropriate enclosures.
• Qts: 0.38 — driver alignment parameter affecting enclosure compatibility and bass shaping.
• BL: 23.90 — motor strength that enhances control of cone motion under heavy drive.
• Vas: 68.30 L — recommended enclosure volume for optimal bass performance.
• Xmech / Xmeh: 45.00 mm — mechanical travel limit indicating how far the cone can move safely.
• Xmax: 22.50 mm — specified linear excursion for distortion-free output.
• Mounting depth: 10.96 inch (278.5 mm) — space required behind the mounting surface for proper installation.
• Cut-out: 13.97 inch (355.0 mm) — hole diameter needed to install the subwoofer.

The D-3515R/D1-D2 is suited for high-performance builds where substantial continuous power, deep bass extension, and flexible amplifier pairing are priorities. Its carbon cone, ferrite magnet, and robust frame work together to maintain control and minimize distortion across demanding listening material and large enclosures.
