AP-M80SQL 4x8 LOUD AS HELL SPL-board Slope V1 – SQL smoothness with razor-sharp SPL treble from AT-32

The AP-M80SQL 4x8 LOUD AS HELL SPL-board Slope V1 is a system that blends the rich, smooth character of SQL-focused midbass drivers with the raw power of Deaf Bonce AT-32 horn tweeters. It’s a package built for those who want both emotion and impact – delivering clarity and definition across the full range.

The AP-M80SQL midbass drivers are designed to play deeper and softer than traditional SPL drivers, without losing control or presence. With rich, detailed reproduction, high build quality, and a frequency range from 150 to 8000 Hz, they provide a smooth yet powerful midrange – ideal for audio builds that prioritize balance and sonic quality.

The highs come from two Deaf Bonce AT-32 horn tweeters – rated at 35W RMS with 108 dB sensitivity and SPL performance that cuts through every mix. They bring an aggressive, sharp top end that perfectly complements the soft, detailed mids with vivid brilliance.

Crossover duties are handled by DB 2-way filters v2, splitting at 4000 Hz (12 dB/oct) and offering three selectable attenuation levels (0, -3, -6 dB) – making it easy to dial in the perfect match between highs and mids.

The entire system is mounted in a LOUD AS HELL 4x8" SPL-board Slope – constructed from heavy-duty MDF, with an angled front for optimized sound dispersion, side-mounted terminal, and embroidered logo on the rear.

AP-M80SQL 4x8 LOUD AS HELL SPL-board Slope V1 is the choice for those who want soft, high-quality midrange – with a treble that slices through with authority.

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.
