Description
The Deaf Bonce Apocalypse AP-M81AC is an 8" midrange driver pair designed for high-detail vocal and midband performance in serious car audio builds. With 300 W RMS and 600 W peak handling, it provides solid power headroom while maintaining clarity across its midrange range.
- Size: 8" diameter driver; built to fit standard 8" midrange installations and uses a 7.56" (192 mm) cut-out for mounting.
- Type: Midrange; optimized for clear vocal articulation and midband content within the 110–10000 Hz range.
- Frequency response: 110–10000 Hz; covers lower midrange up to higher treble, enabling solid vocal presence and instrument realism.
- RMS Power: 300 W; continuous power handling for steady performance without clipping under normal use.
- MAX Power: 600 W; peak capability for brief bursts, giving headroom during transient musical peaks.
- Impedance: 4 Ohm; compatible with a wide range of amplifiers and easy to impedance-match in multi-driver systems.
- SPL: 97.50 dB; higher sensitivity means more output from the same amplifier power, aiding loud, detailed midrange performance.
- Voice coil: 2.00" with CCAW wire; larger coil diameter supports power handling and thermal management for sustained output.
- Cone & surround: Paper cone with cloth surround; chosen combination balances midrange clarity with mechanical control.
- Magnet & frame: Ferrite magnet and cast aluminum frame; rigid construction aids linearity and durability in automotive environments.
- Mounting depth: 3.3" (84 mm); practical clearance requirement for installation in typical doors or kick-panel spaces.
- Cut-out: 7.56" (192 mm); defines the installation opening needed for proper fit.
- Packaging: Package quantity is Pair; ready for stereo installation in front or rear stage configurations.
In a multi-driver front stage, AP-M81AC provides focused midrange output with reliable power handling and a 4 Ohm load that pairs well with many amps. The combination of a solid 2.00" voice coil, ferrite magnet, and cast aluminum frame delivers stable, repeatable midrange performance across demanding listening sessions. The 88 Hz Fs and 0.39 Qts contribute to controlled low-frequency onset and tight midbass integration, helping your system achieve a cohesive vocal image without excessive cone excursion.
