Deaf Bonce Apocalypse D-4518R D1/D2 | 18" Subwoofer

The Deaf Bonce Apocalypse D-4518R D1 / DB-4518 D2 is an 18-inch subwoofer designed for high-power car audio builds, delivering 4500 W RMS with up to 9000 W peak and dual-impedance wiring for flexible amplifier compatibility.

• Size: 18 inch — Large-diameter drivers offer substantial excursion potential for deep, authoritative bass in demanding installations.
• Voice coil size: 4.50 inch — A larger voice coil increases heat handling and power delivery, helping maintain control under heavy bass passages.
• Cone: Carbon — Carbon cones provide rigidity with low mass, aiding fast, precise cone motion at high excursion.
• Magnet: Ferrite — Ferrite magnets support robust magnetic field strength in a compact frame, aiding high-power performance.
• RMS Power: 4500 W — Continuous power handling enables sustained bass output when paired with capable amplifiers.
• MAX Power: 9000 W — Peak power capacity allows brief, high-demand transients without clipping or strain.
• Frame: Alu — Aluminum frame maintains structural rigidity while keeping weight manageable for installation reliability.
• Impedance: 1+1 / 2+2 Ohm — Dual voice-coil configurations provide flexible wiring options to match different amplifiers and loads.
• SPL: 89.00 dB / 89.00 dB — Sensitivity around 89 dB indicates solid output efficiency for its size and power class.
• Fs: 29.40 Hz — Low resonance frequency supports deep bass extension when paired with an appropriate enclosure.
• Qts: 0.34 — A low Qts suggests suitability for vented or tuned enclosure designs to maximize bass impact.
• BL: 28.00 — Strong motor strength contributes precise control of cone motion under high power.
• Vas: 153 L — Indicates a sizeable enclosure is typically required to realize the driver’s full bass potential.
• Xmeh: 45.00 mm — Mechanical travel limit that defines how far the cone and suspension can move safely.
• Xmax: 22.50 mm — Large linear excursion supports deep bass when installed in suitably sized enclosures.
• Mounting depth: 12.87 inch (327.0 mm) — Requires substantial rear depth in the enclosure area or vehicle trunk space.
• Cut-out dimension: 18.2 inch (462.3 mm) — The hole size needed in the enclosure panel to install this 18-inch woofer.

The Apocalypse D-4518R/D-4518 D2 excels in high-power subwoofer builds where a large, rigid 18-inch driver must deliver deep, controlled bass. With dual-impedance wiring, substantial heat handling, and a robust ferrite-magnet architecture, it fits aggressive amplifiers and demanding tuning schemes while demanding a sizable enclosure and precise fitment planning.
