AP-M67AC NEO 4x6.5 LOUD AS HELL Plank Slope V4 – Neodymium Dominance with High-End Precision on Top

The AP-M67AC NEO 4x6.5 LOUD AS HELL Plank Slope V4 is an uncompromising SPL package for those who demand maximum performance from every component. Featuring Deaf Bonce’s most aggressive 6.5" neodymium midbass drivers and the high-end AT-37 Sport horn tweeters, this system doesn’t just play loud – it redefines what loud means when done right.

Powering the mids are four Apocalypse AP-M67AC NEO 6.5" drivers – ultra-compact, insanely powerful neodymium midbass speakers with 300W RMS, fast attack, and a tone character that outperforms many larger drivers. Despite their sleek form factor, these drivers deliver brutal presence, razor-sharp clarity, and raw force that’s hard to beat in this class.

The top end is handled by two AT-37 Sport horn tweeters – high-end units from Deaf Bonce’s Sport series. With a 1.5" voice coil, 60W RMS, 120W max power handling, and 108.8 dB SPL, the AT-37 Sport pushes every detail with surgical precision. A polycarbonate diaphragm and neodymium magnet ensure crisp, strong highs that remain clean even when the system is pushed to its limits. This is the tweeter for those who won’t settle for “just clear enough.”

The system is powered by two DB 2-way filters v2, tuned for 2-ohm operation and optimized for seamless integration between midbass and tweeter. With a crossover point at 4000 Hz (12 dB/oct) and three-step tweeter attenuation (0, -3, -6 dB), you have full control over your sound balance.

Everything is mounted in a dBVox Raggarplanka Slope Style – a robust MDF structure wrapped in black carpet with an embroidered LOUD AS HELL logo. Four 6.5" midbass positions, two tweeter mounts, and a side-mounted terminal make for a simple and stable installation.

The AP-M67AC NEO 4x6.5 LOUD AS HELL Plank Slope V4 is the obvious choice for those who want lightweight punch, razor-sharp attack, and high-end treble control in an uncompromising SPL solution ready for both competition and daily dominance.

NOTE! Sold as a DIY kit.
The tweeter cutouts in the enclosure may be smaller than the included tweeters. 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.
