Deaf Bonce Apocalypse DB-SA305 D1/D2 15" Subwoofer

The Deaf Bonce Apocalypse DB-SA305D1 / DB-SA305D2 is a 15 inch Subwoofer built for high‑power bass applications, offering dual impedance options and a ferrite magnet for rugged, low‑end authority.

• Size: 15 inch cone with a 3.00 inch voice coil — supports high excursion and strong power handling to move more air at demanding volumes.
• Cone: Paper — lightweight, responsive piston action that helps with transient bass and overall clarity.
• Magnet: Ferrite — robust motor structure designed for high‑power operation and durability in car environments.
• Voice coil wire: CCAW — copper clad aluminum windings balance strength and thermal performance under heavy use.
• Surround: Foam — durable, compliant edge to sustain excursion while maintaining alignment through bass range.
• RMS Power: 2000 W — means capable of continuous high‑level bass without sustained distortion when driven by a suitable amplifier.
• MAX Power: 4000 W — indicates high transient capability for brief peak demands in music with dynamic dynamics.
• Frame: Alu — aluminum chassis provides rigidity and lighter weight with effective heat dissipation.
• Impedance: 1+1 / 2+2 Ohm — dual‑impedance design lets you match the woofer to a range of amplifiers for optimal load and damping.
• SPL: 88.30 / 88.60 dB — sensitivity figures to gauge output potential relative to input power in typical testing conditions.
• Fs: 31.70 / 32.00 Hz — low resonant frequency indicating strong bass extension into the subbass region.
• Qts: 0.40 / 0.43 — electrical alignment parameter that influences how the woofer behaves in different enclosure types.
• BL: 18.50 / 18.70 — motor strength indicator correlating to control and stiffness of bass response.
• Vas: 61.00 / 63.00 L — suggested enclosure volume range for achieving balanced low‑end performance.
• Xmax: 18.00 / 18.00 mm — maximum linear excursion, contributing to deep, defined bass under heavy program material.
• Mounting depth: 7.85 inch — installation clearance needed in vehicle enclosures.
• Cut‑out dimension: 14.09 inch — hole size required for mounting this subwoofer in a panel or enclosure.

In real-world builds, this subwoofer suits high‑power systems that demand substantial continuous output, flexible wiring options, and a robust motor for controlled bass. Its dual impedance and sizable excursion translate to strong performance across a range of enclosure designs, with enclosure volume guidance reflected by Vas and SPL values that help estimate system efficiency and required amplification.
