AP-M61SE PRO 4x6.5 LOUD AS HELL Plank Slope V1 – Sylvester PRO-Class Meets Sporty Treble Control

The AP-M61SE PRO 4x6.5 LOUD AS HELL Plank Slope V1 is built for those who demand powerful midrange performance and precise treble control, without compromising on reliability or sound quality. Featuring the Sylvester Series PRO midbass and the sport-class AT-32 Sport horn tweeters, this package delivers pure, uncompromising performance – ready to hit hard out of the box.

At the heart of the system are four Apocalypse AP-M61SE PRO 6.5" midrange drivers. With 150W RMS, 300W max power, 1.3" CCAW voice coil, paper cone, and a rugged steel basket, these midbass drivers are built to withstand pressure – and deliver. The wide frequency range of 100–15,000 Hz provides rich reproduction, and the 102.8 dB sensitivity ensures maximum output per watt.

High frequencies are handled by two AT-32 Sport horn tweeters – compact but powerful, with 60W RMS, 120W max, polycarbonate diaphragms, neodymium magnets, and 108.3 dB sensitivity. They are designed to deliver crisp and clear highs even at high volumes, perfectly balanced with the midbass punch.

The system is wired via two DB 2-way filters v2, designed for 2-ohm operation with dual 4-ohm midbass drivers and tweeters. With a crossover point at 4000 Hz (12 dB/oct) and a three-step attenuation (-0, -3, -6 dB) on the tweeters, you can fine-tune the treble level to match your desired sound profile.

Everything to be installed in a dBVox Raggarplanka Slope Style – solid MDF build, covered in black carpet, and finished with an embroidered LOUD AS HELL logo. Four 6.5" cutouts, two tweeter mounts, and a side-mounted terminal ensure quick and stable installation.

The AP-M61SE PRO 4x6.5 LOUD AS HELL Plank Slope V1 is the package for you if you want PRO-level midrange performance and tweeters that can keep up – whether you're prepping for competition or powering through heavy daily sessions.

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