Deaf Bonce Apocalypse DB-3015R D1/D2

The Deaf Bonce Apocalypse DB-3015R D1 / DB-3015 D2 is a 15-inch dual-voice-coil subwoofer built for high-power car-audio systems, delivering substantial bass with flexible impedance options.

• Model: DB-3015R D1 / DB-3015 D2 — dual-variant 15" subwoofer designed for different wiring configurations.
• Type: Subwoofer — engineered for deep bass reproduction in automotive enclosures.
• Size: 15" — large-diameter driver suited for low-frequency extension and high excursion.
• Voice coil size: 3.00" — larger coil supports higher power handling and heat dissipation for sustained output.
• Cone: Paper — rigid enough for accurate transient response while remaining cost-effective.
• Magnet: Ferrite — provides a sturdy magnetic structure to support strong motor force at high power.
• Surround: Foam — accommodates substantial cone travel with controlled damping.
• RMS Power: 2800 W — continuous power handling for demanding installations.
• MAX Power: 5600 W — peak capability for transient bursts in high-output systems.
• Frame: Alu — lightweight, rigid structure aiding mounting reliability in tight spaces.
• Impedance: 1+1 / 2+2 Ohm — supports flexible dual-voice-coil wiring for different amplifier pairings.
• SPL: 88.00 / 88.30 dB — sensitivity indicating acoustic output per watt across variants.
• Fs: 32.00 / 32.50 Hz — low-frequency onset, enabling strong bass extension in appropriate enclosures.
• Qts: 0.45 / 0.47 — system tuning parameter influencing enclosure alignment and bass response.
• BL: 23.00 / 26.10 — motor strength contributing to linearity and control at high excursion.
• Vas: 68.00 / 69.70 L — recommended enclosure volume range for proper loading and bass sensitivity.
• Xmeh: 1.50" (38.00 mm) — mechanical travel limit before physical stopper contact.
• Xmax: 0.75" (19.00 mm) — maximum linear excursion before distortion or mechanical impact occurs.
• Mounting depth: 10.18" (258.5 mm) — depth required in the vehicle cavity for proper installation.
• Cut-out dimension: 13.98" (355.0 mm) — hole diameter needed for mounting the subwoofer.
• Gross weight: 68.34 lb (31.00 kg) — overall weight affecting enclosure support and mounting considerations.

The DB-3015R D1 / DB-3015 D2 excels in high-power, SPL-focused builds where dual-voice-coil flexibility and substantial enclosure loading are key. Its dual impedance options enable versatile amp matching, while the large 15" cone, ferrite magnet, and foam surround support strong bass with controlled excursion. With mounting depth and cut-out dimensions clearly defined, it suits sizeable enclosures and installations requiring robust, repeatable low-frequency performance.
