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 seeking strong and reliable midrange performance from the Sylvester series, paired with fast, clear, and efficient treble from the Deaf Bonce AT-32 Sport. A well-balanced package for those who want to play both clean and loud – for the long haul.

The AP-M81SE midbass drivers are 8-inch speakers from Deaf Bonce’s Sylvester series, known for their combination of high performance and reasonable pricing. With 170W RMS power handling and an operating range of 150–8000 Hz, they deliver punchy dynamics and clear reproduction in the midrange – even in demanding environments.

The treble is handled by two Deaf Bonce AT-32 Sport horn tweeters, featuring neodymium magnets, polycarbonate diaphragms, 37W RMS power, and a sensitivity of 108.3 dB. The result is fast and precise top-end response, without excessive harshness – just right to complement the power of the Sylvester midbass without overpowering it.

The system is wired using DB 2-way filters v2, with a 4000 Hz crossover (12 dB/oct) and three-stage attenuation (0, -3, -6 dB), allowing you to fine-tune the treble level according to your build and taste.

Designed for installation in a LOUD AS HELL 4x8" SPL-board Slope – constructed from durable MDF with an angled front, side-mounted terminal, and embroidered LOUD AS HELL logo.

The AP-M81SE 4x8 LOUD AS HELL SPL-board Slope V3 is the choice for those who want Sylvester’s dependable midrange strength paired with a snappy and efficient treble to lift the entire system.

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