Deaf Bonce Apocalypse D-4515R D1/D2 | 15" Subwoofer

The Deaf Bonce Apocalypse D-4515R / 15" subwoofer is built for extreme, power‑hungry car audio builds, delivering deep, controlled bass with flexible impedance options. It features a carbon cone and ferrite magnet to handle high wattage in demanding installations.

• Size: 15 inch – Large diaphragm area yields substantial displacement for deeper bass in properly sized enclosures.
• Voice coil size: 4.50 inch – A bigger coil improves heat dissipation and sustained power handling.
• Cone: Carbon – High stiffness-to-weight ratio supports precise control during aggressive excursions.
• Magnet: Ferrite – Provides a strong magnetic field in a compact, durable assembly.
• Frame: Alu – Aluminum frame adds rigidity while keeping weight manageable for high‑volume bass.
• RMS Power: 4500 W – Continuous power rating suitable for demanding amplifiers and sustained output.
• MAX Power: 9000 W – Peak capability for short, high‑power bursts without clipping.
• Impedance: 2+2 / 1+1 Ohm – Dual voice coils allow flexible wiring to match a variety of amplifiers and configurations.
• SPL: 87.70 dB – Sensitivity figure indicating how efficiently the driver converts power into sound at a reference distance.
• Fs: 32 Hz – Lower frequency limit indicating bass extension into the subwoofer’s operating range.
• Qts: 0.35 – Electrical Q value guiding enclosure alignment choices (sealed vs. vented).
• BL: 26.20 – Motor strength indicator contributing to the woofer’s control and linearity.
• Vas: 67 L – Recommended enclosure volume range for typical alignment and performance.
• Xmax: 22.50 mm – Maximum linear excursion before distortion, defining usable travel for deep bass.
• Mounting depth: 11.94 inch (303.5 mm) – Depth requirement that dictates installation space in dashboards, doors, or trunks.
• Cut-out dimension: 13.97 inch (355.0 mm) – Actual hole size needed for proper mounting in the enclosure opening.

In a high‑power system, this subwoofer thrives in large enclosures that respect its 67 L Vas, delivering deep, controlled bass with solid mechanicals and a robust aluminum frame. The dual impedance and substantial Xmax enable flexible amp matching and strong bass authority, making it well suited for trunk or SUV builds where precise control and peak output matter.
