Deaf Bonce Apocalypse DB-SA255 D1/D2 15" Subwoofer

The Deaf Bonce Apocalypse DB-SA255D1 / DB-SA255D2 is a 15-inch subwoofer built for high‑output bass in demanding car audio systems, pairing a ferrite magnet with a 2.50-inch voice coil to handle serious power while maintaining control.

• Type: Subwoofer — a dedicated driver for low-frequency output in an audio system.
• Size: 15 inch — a large cone diameter that moves more air for impactful bass response.
• Voice coil size: 2.50 inch — a larger coil supports higher power handling and heat dissipation.
• Cone: Paper — lightweight, compliant material that aims for efficient motion and detailed low end.
• Magnet: Ferrite — common for high‑power woofers, providing sturdy magnetic bias at a favorable price-to-performance ratio.
• Voice coil wire: Copper — conducts current with good conductivity and reliability under load.
• Surround: Foam — helps control excursion and durability through repeated cone movement.
• RMS Power: 1000 W — continuous power handling, guiding amplifier matching for sustained bass performance.
• MAX Power: 2000 W — peak power capability for transient bass demands when driven conservatively by a capable amp.
• Frame: Alu — lightweight, rigid construction that supports aggressive excursion while aiding heat management.
• Impedance: 1+1 / 2+2 Ohm — dual‑coil configuration offering flexible wiring options to suit different amplifiers.
• SPL: 87.10 / 87.50 dB — sensitivity figures indicating how efficiently the driver converts power to sound in the given coil configurations.
• Fs: 32.20 / 32.86 Hz — resonant frequency range; contributes to low‑end extension when paired with a proper enclosure.
• Qts: 0.51 / 0.55 — system tuning parameter reflecting how the driver behaves in a box and across frequency bands.
• BL: 20.12 / 20.83 — motor strength indicator, impacting how tightly the cone follows the input signal under excursion.
• Vas: 61.30 / 62.10 L — equivalent enclosure volume guidance for designing appropriate sealed or ported boxes.
• Xmax: 15.00 / 15.00 mm — maximum linear excursion, shaping how far the cone can move before non‑linear distortion sets in.
• Mounting depth: 7.40 inch — depth to clearance in the vehicle; informs compatibility with installation spaces.
• Cut-out dimension: 14.09 inch — diameter of the mounting hole required for installation.
• Gross weight: 29.98 lb (13.60 kg) — packaged weight for shipping considerations and overall heft in vehicle installs.

In a properly designed enclosure, the DB-SA255D1 / DB-SA255D2 provides high‑power bass with flexible impedance options, robust mechanical build, and practical mounting dimensions that fit a wide range of vehicle installations while maintaining controlled, low‑end extension. The dual coil and ferrite magnet configuration supports versatility in amplifier pairing and installation layouts for enthusiasts chasing loud, accurate bass without compromising system stability.
