AP-W81AC 4x8 LOUD AS HELL SPL-board Slope V1 – Deep Arnold bass with SPL clarity from AT-32

The AP-W81AC 4x8 LOUD AS HELL SPL-board Slope V1 is built for those who want to squeeze out every decibel and every Hz from their midrange – and feel the sound as much as hear it. With four brutal Apocalypse AP-W81AC 8" midbass drivers and two SPL-optimized Deaf Bonce AT-32 tweeters, this board delivers deep, raw power with razor-sharp high-frequency control.

The midbass drivers, AP-W81AC, are the next evolution in the Arnold series. With 300W RMS, lowered resonance frequency (FS), and maintained extreme sensitivity, these drivers deliver deeper and more powerful bass response while keeping the raw midrange presence. Recommended frequency range: 150–8000 Hz.

The highs are handled by two Deaf Bonce AT-32 horn tweeters – optimized for SPL use, with 35W RMS, 108 dB sensitivity, and the ability to cut through even the loudest systems with crystal clarity. These ensure the details in the top end not only survive – they shine.

The system is connected via DB 2-way filters v2, with a crossover point at 4000 Hz (12 dB/oct) and three-level tweeter attenuation (0, -3, -6 dB), for perfect balance between midbass and highs.

Everything is mounted in a solid LOUD AS HELL 4x8" SPL-board Slope – MDF construction, angled design, side-mounted terminal, and embroidered LOUD AS HELL logo. Four 8" midbass slots and two tweeter cutouts make installation both simple and secure.

The AP-W81AC 4x8 LOUD AS HELL SPL-board Slope V1 is your go-to choice if you want deep bass, raw power, and extreme SPL performance – topped with a high-frequency section that keeps up when it really matters.

NOTE! This package is sold as a DIY kit.
The tweeter cutout in the enclosure may be smaller than the included tweeters. This is intentional to support compatibility with a wider range of tweeters. Minor adjustments (e.g., using a rasp) may be needed to achieve a perfect fit.
