AP-M81AC NEO 4x8 LOUD AS HELL SPL-board Slope V4 – Arnold precision meets high-end sport tweeter

The AP-M81AC NEO 4x8 LOUD AS HELL SPL-board Slope V4 is built for those who want to combine high endurance, explosive midrange attack, and even more refined top-end detail. Featuring four Apocalypse AP-M81AC NEO 8" midrange drivers and two Deaf Bonce AT-37 Sport horn tweeters, this system delivers pure Arnold performance with high-end treble control.

The AP-M81AC NEO midbass drivers are made to withstand extreme loads, rated at 300W RMS, with a neodymium magnet system and operating range from 150 to 8000 Hz. Their high sensitivity and durability ensure powerful punch, clear mids, and dynamic response even during prolonged high-SPL playback.

High frequencies are handled by two Deaf Bonce AT-37 Sport horn tweeters – an even sharper SPL-focused solution with 60W RMS, 120W max, 1.5" voice coil, polycarbonate diaphragm, neodymium magnet, and a sensitivity of 108.8 dB. They offer a wider, smoother, yet still extremely powerful top-end, ideal for those seeking maximum clarity without harshness.

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

It’s all housed in a robust LOUD AS HELL 4x8" SPL-board Slope – a solid MDF construction with angled design for optimal dispersion, side-mounted terminal, and an embroidered LOUD AS HELL logo.

The AP-M81AC NEO 4x8 LOUD AS HELL SPL-board Slope V4 is the ideal choice if you're looking for Arnold-grade endurance and midrange precision paired with top-end reproduction that defines every detail – both SPL-strong and musically accurate.

NOTE! This package is sold as a DIY kit.
The tweeter hole in the enclosure may be smaller than the delivered tweeters. This is to allow compatibility with most tweeters in the included universal enclosure. Some light filing or adjustment may be needed for a perfect fit.
