AP-M81AC 4x8 LOUD AS HELL SPL-board Slope V5 – Arnold muscle with crystal-clear precision from MLT-15

The AP-M81AC 4x8 LOUD AS HELL SPL-board Slope V5 is a system built for those who want to combine maximum midrange pressure from the Arnold series’ most powerful 8-inch drivers with crystal-clear, enveloping treble reproduction from the new Deaf Bonce MLT-15 tweeters.

The AP-M81AC midrange drivers are a true icon in the SPL world. With 300W RMS, high sensitivity, and a frequency range of 150–8000 Hz, these speakers deliver explosive dynamics, massive presence, and controlled midrange performance that few others can match.

The treble is elevated to a new level with two Deaf Bonce Machete MLT-15 1" Neodymium Tweeters. With 25W RMS, 50W peak, and a working range from 5000 Hz to 20000 Hz, these tweeters provide sharp, clear, and airy high frequencies. The neodymium magnet system ensures high efficiency and better sensitivity, allowing the tweeters to stay clear and present even at higher volumes.

The system uses DB 2-way filters 10k – with crossover at 10 000 Hz (12 dB/oct) and three-step adjustable tweeter attenuation (0, -3, -6 dB), offering flexible tuning for both midbass pressure and treble clarity.

Everything is installed in a LOUD AS HELL 4x8" SPL-board Slope – a robust MDF construction with angled design for optimal dispersion, side-mounted terminal, and embroidered LOUD AS HELL logo.

The AP-M81AC 4x8 LOUD AS HELL SPL-board Slope V5 is the choice for those who want raw Arnold midrange power, topped with crystal-clear and fast treble precision from one of the market’s most modern tweeters.

NOTE! This package is sold as a DIY kit.
The tweeter cutout 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.
