Deaf Bonce Apocalypse DB-SA275 D1/D2 15" Subwoofer

The Deaf Bonce Apocalypse DB-SA275D1 / DB-SA275D 15" Subwoofer is a dual-voice-coil, high-power 15-inch driver built for extreme bass in premium car audio systems. It combines a 2.75" voice coil, ferrite magnet, and aluminum frame to deliver serious output with solid thermal and mechanical stability.

• Size: 15 inch — provides a large radiating area for substantial displacement and deep bass potential.
• Voice coil size: 2.75 inch — a larger coil aids heat dissipation and power handling during demanding tracks.
• Cone: Paper — keeps cone weight low for quick transient response while maintaining stiffness.
• Magnet: Ferrite — ferrite magnet supports a strong magnetic field within a compact package.
• Voice coil wire: CCAW — copper-clad aluminum wire reduces weight while carrying current efficiently.
• Surround: Foam — foam surround accommodates long excursion with controlled cone motion.
• RMS Power: 1500 W — continuous power handling for sustained, high-output playback.
• MAX Power: 3000 W — peak power capability to manage transient spikes in music.
• Frame: Alu — aluminum frame provides rigidity while aiding heat dissipation.
• Impedance: 1+1 / 2+2 Ohm — dual-voice-coil wiring options for flexible amplifier matching.
• SPL: 88.00 / 88.20 dB — sensitivity values for the two coil configurations, indicating on-axis output potential.
• Fs: 29.70 / 31.30 Hz — low-frequency resonance range, signaling strong sub-bass capability.
• Qts: 0.42 / 0.46 — electrical damping factor, relevant to enclosure tuning and transient behavior.
• BL: 18.60 / 19.10 — motor strength metric, relating to force on the voice coil.
• Vas: 62.00 / 64.00 L — recommended enclosure volume range for proper system alignment.
• Xmax: 18.00 / 18.00 mm — maximum linear excursion to achieve deep bass before distortion.
• Mounting depth: 7.85 inch — installation depth required behind the mounting surface.
• Cut-out dimension: 14.09 inch — hole size needed for proper mounting in an enclosure or vehicle.
• Gross weight: 33.51 lb (15.20 kg) — substantial, sturdy driver suitable for secure mounting in rugged installations.

The DB-SA275D1 / DB-SA275D 15" Subwoofer is built for serious bass in high-output installations. Its dual-voice-coil design and flexible impedance pairing let you tailor amplifier loading, while the 2.75" voice coil, ferrite magnet, and aluminum frame balance power handling with structural rigidity. With 1500 W RMS and 3000 W peak, it handles demanding tracks and transients, and its notable Xmax and Vas values guide enclosure design for meaningful low-end extension. Plan for a 7.85" mounting depth and a 14.09" cut-out to ensure a proper fit in your build.
