AP-M67AC 4x6.5 LOUD AS HELL Plank Slope V4 – Ferrite Brutality with High-End Top-End Control

The AP-M67AC 4x6.5 LOUD AS HELL Plank Slope V4 is an SPL monster for those who want to push every component – and every decibel – to the limit. With Deaf Bonce’s most powerful 6.5" ferrite midrange drivers and the advanced AT-37 Sport horn tweeters, this system delivers punch, clarity, and durability without compromise.

At the system’s core are four Apocalypse AP-M67AC 6.5" midrange drivers – Deaf Bonce’s flagship ferrite models. With 300W RMS, 600W musical power, a massive 1.75" voice coil, and a powerful magnet structure, these midbass speakers are built to perform under extreme pressure. They play loud, hard, and long – with sound pressure you can feel in your chest.

The high frequencies are handled by two AT-37 Sport horn tweeters – a high-end solution for those who demand uncompromising treble performance. With 60W RMS, 120W max, polycarbonate diaphragms, 1.5" voice coils, and an SPL of 108.8 dB, the AT-37 Sport delivers sharp and detailed highs that carry all the way through. The neodymium magnet ensures high efficiency and rapid response – even in the most demanding setups.

The system is wired through two DB 2-way filters v2, specially tuned for 2-ohm operation. With a crossover point at 4000 Hz (12 dB/oct) and three-step attenuation (0, -3, -6 dB) on the tweeters, you have full control over the tonal balance.

Everything is mounted in a dBVox Raggarplanka Slope Style – built from heavy MDF, covered in black carpet, and embroidered with the LOUD AS HELL logo. Four 6.5" slots, two tweeter mounts, and a side-mounted terminal make the system ready for immediate installation.

The AP-M67AC 4x6.5 LOUD AS HELL Plank Slope V4 is the plank for those who want ferrite weight, elite-level SPL, and tweeters that match in every detail – built to be heard and felt.

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