AP-M81SE 4x8 LOUD AS HELL SPL-board Slope V1 – Sylvester power meets raw SPL from AT-32

The AP-M81SE 4x8 LOUD AS HELL SPL-board Slope V1 is the go-to package for those who want the affordable yet powerful midrange performance of the Sylvester series, paired with a sharp SPL tweeter from Deaf Bonce AT-32. The result is a system that plays loud, clear, and with punch – without pushing the limits of your budget.

The midbass drivers, Apocalypse AP-M81SE, are 8" midrange speakers from Deaf Bonce’s Sylvester series – built to handle 170W RMS, play from 150 Hz to 8000 Hz, and deliver a clear, punchy, and reliable sound in the midrange. Perfect for those who value performance over price tags.

The highs are handled by two Deaf Bonce AT-32 horn tweeters – SPL-optimized with 108 dB sensitivity, 35W RMS power handling, and the ability to deliver clear and piercing highs even at elevated volumes. An ideal match to balance the Sylvester midbass with clean and powerful top-end presence.

The crossover is handled by DB 2-way filters v2, with a 4000 Hz split (12 dB/oct) and three-stage attenuation (0, -3, -6 dB) for precise balance between mids and highs.

The system is designed for installation in a LOUD AS HELL 4x8" SPL-board Slope – built from sturdy MDF with an angled front, embroidered LOUD AS HELL logo, and side-mounted terminal.

AP-M81SE 4x8 LOUD AS HELL SPL-board Slope V1 is the choice for those who want budget-friendly midrange power and raw SPL highs with distinct character – ready to impress both in sound and in show.

NOTE! This package is sold as a DIY kit.
The tweeter holes 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 file or similar tool to widen the hole for a perfect fit.
