AP-M81SE 4x8 LOUD AS HELL SPL-board Slope V3 – Sylvester punch with sport-tuned top-end control

The AP-M81SE 4x8 LOUD AS HELL SPL-board Slope V3 is built for those who want strong and reliable midrange delivery from the Sylvester series, paired with fast, clear, and efficient treble from the Deaf Bonce AT-32 Sport. A well-balanced setup for playing both clean and loud – for extended sessions.

The midbass drivers, AP-M81SE, are 8" units from Deaf Bonce’s Sylvester series, known for their high performance at a reasonable price. With 170W RMS handling and a working range from 150–8000 Hz, they deliver punchy dynamics and clear midrange reproduction – even in demanding environments.

The top end is handled by two Deaf Bonce AT-32 Sport horn tweeters, featuring neodymium magnets, polycarbonate diaphragms, 37W RMS power handling, and 108.3 dB sensitivity. The result is quick and precise treble, without excessive sharpness – just the right match for the Sylvester mids’ punch, without overpowering them.

The system is wired through DB 2-way filters v2, with a 4000 Hz crossover point (12 dB/oct) and three-stage attenuation (0, -3, -6 dB), allowing you to fine-tune the treble output based on your setup and preferences.

Everything is mounted in a LOUD AS HELL 4x8" SPL-board Slope – MDF construction, angled baffle, side-mounted terminal, and embroidered LOUD AS HELL logo for a clean and pro look.

AP-M81SE 4x8 LOUD AS HELL SPL-board Slope V3 is the choice for those who want the dependable strength of the Sylvester series in the low end, with a snappy and efficient treble that lifts the entire system.

NOTE! This package is sold as a DIY kit.
The tweeter holes in the enclosure may be smaller than the tweeters provided. This is to accommodate most tweeters in the included universal enclosure. You may need to use a file or similar tool to widen the holes for a perfect fit.
