AP-M81AC NEO 4x8 LOUD AS HELL SPL-board Slope V1 – Arnold NEO-efficiency meets SPL peaks with AT-32

The AP-M81AC NEO 4x8 LOUD AS HELL SPL-board Slope V1 is designed for those who demand endurance, extreme sensitivity, and pure SPL performance in every tone. With four powerful Apocalypse AP-M81AC NEO 8" midrange drivers and two Deaf Bonce AT-32 horn tweeters, this system delivers brutal strength and clarity from midbass to treble.

The AP-M81AC NEO midbass drivers represent one of the most advanced constructions in the Arnold series – with 300W RMS, a neodymium magnet, and 2.3T gap induction. They offer an exceptionally wide working range from 150 Hz to 8000 Hz, built to withstand extreme stress without sacrificing sound quality. The result is hard punch, clear mids, and fantastic dynamics across the spectrum.

The highs are taken to the next level with two Deaf Bonce AT-32 horn tweeters – optimized for SPL systems, with 108 dB sensitivity, 35W RMS, and 200W music handling capacity when filtered. The AT-32 delivers exceptionally high SPL levels with retained clarity and endurance, making them ideal for systems that need to perform under competition or heavy play.

The system uses DB 2-way filters v2, with a crossover point at 4000 Hz (12 dB/oct) and three-stage attenuation (0, -3, -6 dB) for optimal balance between midbass and tweeter.

The system is designed for installation in a LOUD AS HELL 4x8" SPL-board Slope – made of heavy-duty MDF, with side-mounted terminals and an embroidered LOUD AS HELL logo on the rear.

AP-M81AC NEO 4x8 LOUD AS HELL SPL-board Slope V1 is the package for those who want the best of Arnold-series precision and endurance, combined with pure SPL attack from the Deaf Bonce AT-32. A system that doesn’t just get heard – it dominates.

NOTE! This package is sold as a DIY kit.
The tweeter hole in the enclosure may be smaller than the supplied tweeters. This is to ensure compatibility with most tweeter models in the included universal enclosure. A rasp or similar tool may be needed to adjust the hole for a perfect fit.
