Deaf Bonce Apocalypse 4512R 4500 Watt RMS 12" D1/D2

The Deaf Bonce Apocalypse 4512R is a 12-inch, dual-impedance subwoofer built for high-power car audio systems, delivering stiff, controlled bass through a carbon cone and robust ferrite magnet system.

• Size: 12 inch — a large woofer footprint designed to move substantial air for deep bass extension and strong transient response.
• Voice coil size: 4.50 inch — a larger coil improves heat handling during sustained high-power playback and supports aggressive excursion demands.
• Cone: Carbon — high stiffness-to-weight ratio aids precise cone motion and reduces distortion at high output.
• Magnet: Ferrite — provides a sturdy motor structure suitable for demanding installations while keeping size practical.
• Surround: Foam — provides a compliant, durable suspension that supports long-throw bass without excessive distortion.
• RMS Power: 4500 W — continuous power rating for demanding, high-output listening scenarios with appropriate amplification.
• MAX Power: 9000 W — peak power handling for brief transients and bursts in dynamic musical passages.
• Frame: Alu — aluminum frame contributes to rigidity while remaining lightweight for installation fitment.
• Impedance: 2+2 / 1+1 Ohm — dual voice coil wiring options allow flexible matching to amplifiers and enclosure designs.
• SPL: 85.4 / 85.8 dB — sensitivity, indicating expected output level per watt for each configuration and setup.
• Fs: 39.00 / 40.00 Hz — resonant frequency affecting usable low-end extension and enclosure tuning considerations.
• Qts: 0.57 / 0.59 — thiele-small parameter guiding enclosure alignment and overall bass character.
• BL: 25.10 / 26.10 — motor strength metric influencing control at high excursion and low-distortion playback.
• Vas: 37.00 / 38.20 L — equivalent enclosure volume guidance for achieving target bass output.
• Xmeh: 45.00 / 45.00 mm — mechanical excursion limit, defining how far the cone can move before distortion or damage.
• Xmax: 22.50 / 22.50 mm — maximum linear excursion, indicating safe, usable travel for clean bass with power.

Benefits: Designed for high-demand builds, this sub handles 4500 W RMS and offers dual-impedance wiring to tailor load to your amp and enclosure. The carbon cone and aluminum frame deliver precise, low-distortion bass with strong control, while the foam surround supports long-throw operation. Its impedance options and Thiele–Small parameters provide flexibility for both sealed and ported setups, making it suitable for competition-grade installations or premium daily drivers seeking serious low-end impact.
