AP-M81SE 4x8 LOUD AS HELL SPL-board Slope V2 – Sylvester low-end with razor-sharp neodymium top end

The AP-M81SE 4x8 LOUD AS HELL SPL-board Slope V2 is a powerful and balanced system for those who want the raw midrange performance of the Sylvester series combined with a high-performance neodymium tweeter from Deaf Bonce. This setup delivers clarity and aggressive output – without sacrificing resolution or control.

The AP-M81SE midbass drivers offer 170W RMS and are known for their excellent mix of affordability, strength, and dependable sound character. With a frequency response of 150 Hz to 8000 Hz, they provide a punchy yet controlled reproduction in the midrange – ideal for those building systems that balance power with musicality.

The highs are handled by two Deaf Bonce AP-T25 NEO V2 horn tweeters – with neodymium magnets, 100W RMS power handling, and 108 dB sensitivity, they deliver detailed and powerful top-end performance, even when pushed hard. A perfect match to keep pace with the intensity of the midrange.

The system is connected via DB 2-way filters v2, crossing at 4000 Hz (12 dB/oct) and offering three-stage attenuation (0, -3, -6 dB) for easy fine-tuning between the top end and the mids.

The entire setup is designed for installation in a LOUD AS HELL 4x8" SPL-board Slope – built from heavy-duty MDF, featuring an angled front, side-mounted terminal, and embroidered LOUD AS HELL logo.

AP-M81SE 4x8 LOUD AS HELL SPL-board Slope V2 is a reliable and well-balanced choice for anyone seeking Sylvester midrange performance paired with clear, enduring treble at the top.

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 enclosure. You may need to use a file or similar tool to widen the hole for a perfect fit.
