Deaf Bonce Apocalypse AP M81SE 8" Mid-Range Speakers (Pair)

Deaf Bonce Apocalypse AP M81SE 8" Midrange Speakers (Pair) deliver authoritative vocal clarity from an 8-inch midrange chassis, built for car audio enthusiasts who demand detailed midband performance and solid power handling. With 170 W RMS (340 W max) and a 110–10000 Hz response, this pair is tuned for clear, articulate midrange output in a variety of installations.

• Type: Midrange — tailored for midband reproduction to deliver crisp vocals and defined upper harmonics within the audible range.
• Size: 8" — fits standard 8" openings, suitable for doors or kick-panel deployments where midrange clarity is required.
• Frequency response: 110-10000 Hz — spans from the lower midrange through the high end, enabling detailed speech and musical detail across a broad band.
• Package quantity: Pair — two drivers supplied for a balanced stereo/bi-amp or multi-speaker setup.
• Voice coil size: 1.50" — larger coil aids heat dissipation and power handling for sustained midrange performance.
• Cone: Paper — provides rigid, damped midrange movement for accurate transient response.
• Magnet: Ferrite — compact yet effective motor structure to support consistent excursion and control.
• Voice coil wire: CCAW — lightweight, durable winding that supports efficient current transfer and heat management.
• Surround: Cloth — durable edge that supports linear excursion and longevity in harsh automotive environments.
• RMS Power: 170 W — continuous power handling to sustain clean midrange output under musical dynamics.
• MAX Power: 340 W — peak capability to accommodate transient peaks without clipping.
• Frame: Steel — rigid mounting structure that resists deformation and aids in heat management.
• Impedance: 4 Ohm — compatible with a wide range of car amplifiers and typical system loads for efficient power delivery.
• SPL: 95.10 dB — sensitivity indicating workable output levels with standard automotive amplification.
• Fs: 110 Hz — resonant frequency guiding enclosure alignment and low-end extension planning.
• Qts: 0.66 — parameter describing damping and enclosure behavior for system design.
• BL: 8.15 — motor strength factor influencing control and efficiency of the voice coil.
• Vas: 15.21 L — enclosure volume reference used to predict bass alignment and overall midrange performance.
• Mounting depth: 3.44" (87.5 mm) — depth requirement to fit behind panels or in shallow mounting locations.
• Cut-out dimension: 7.32" (186.0 mm) — hole size needed for proper installation.
• Gross weight: 13.82 lb (6.27 kg) — shipping/handling mass for a pair, indicating a sturdy build.

The AP M81SE pair is well-suited for midrange duties in a two- or multi-driver setup where vocal clarity and consistent midband output are priorities. Its combination of a 4-ohm load, robust power handling, and a broad 110 Hz–10 kHz range supports reliable performance in typical automotive environments while offering predictable enclosure and system integration characteristics.
