AP-M67AC 4x6.5 LOUD AS HELL Plank Slope V3 – Brutal Ferrite Power Meets Sporty Treble Precision

The AP-M67AC 4x6.5 LOUD AS HELL Plank Slope V3 is an uncompromising sound solution for those who want to squeeze every last decibel from their system. With Deaf Bonce’s most powerful 6.5" ferrite midrange drivers and the high-performance AT-32 Sport horn tweeters, you get a system that delivers brutal midrange pressure and razor-sharp highs – without sacrificing control or clarity.

At the core are four Apocalypse AP-M67AC 6.5" midrange drivers – Deaf Bonce’s most power-tolerant ferrite-based mids. Featuring a huge 1.75" voice coil, 300W RMS, and up to 600W music handling, the AP-M67AC is built to withstand long, extreme sessions. Their high efficiency and massive magnet assembly mean these drivers play louder, cleaner, and harder than most in the 6.5" class.

The treble is handled by two DeafBonce AT-32 Sport horn tweeters – optimized for high-frequency efficiency and precision. With 37W RMS, 108.3 dB sensitivity, and polycarbonate diaphragms, these tweeters deliver crisp, distinct highs that cut through even the most intense midrange pressure. Their compact and clever design also makes them easy to install.

Two DB 2-way filters v2 handle the crossover between mids and tweeters with a 4000 Hz crossover point (12 dB/oct) and three-step attenuation (0, -3, -6 dB) to give you control over the system’s balance and tonal character.

All of this is mounted in a dBVox Raggarplanka Slope Style – made from thick MDF, wrapped in black carpet, and finished with an embroidered LOUD AS HELL logo. Four 6.5" slots, two tweeter mounts, and a side-mounted terminal make the installation both simple and rock-solid.

The AP-M67AC 4x6.5 LOUD AS HELL Plank Slope V3 is the choice for those demanding the fiercest Deaf Bonce can offer in ferrite format – with a tweeter that keeps up, and a system that delivers full-blown pressure from the first volume twist.

NOTE! Sold as a DIY kit.
The tweeter cutouts in the enclosure may be smaller than the tweeters included. This ensures compatibility with most tweeters in the supplied universal box. You may need to use a rasp or similar tool to widen the hole for a perfect fit.
