AP-M60SQL 4x6.5 LOUD AS HELL Plank Slope V3 – Sylvester Series HiFi Hybrid with SPL Potential and High-End Top End

The AP-M60SQL 4x6.5 LOUD AS HELL Plank Slope V3 is the perfect choice for those who want more than just brutal pressure – you want sound that truly *sounds* great. With Deaf Bonce’s AP-M60SQL from their popular Sylvester series and the advanced AT-37 Sport tweeter, this system blends HiFi character with SPL capability in a ready-to-install plank format.

At the core of the system are four Apocalypse AP-M60SQL 6.5" midrange drivers – a SQL/SPL hybrid that delivers musical precision with the ability to unleash aggressive output. With 150W RMS, an extra durable construction, and a frequency range of 110–8000 Hz, these speakers are built for detailed playback that doesn't back down when the volume goes up. As part of the Sylvester series, they deliver impressive performance in both sound quality and price – ideal if you want the best of both worlds.

The highs are handled by two AT-37 Sport horn tweeters, rated at 60W RMS, 120W max, with a 1.5" voice coil and 108.8 dB SPL. Thanks to polycarbonate diaphragms and neodymium magnets, you get crisp, distinct treble with fast response and power – a perfect match for the dynamic nature of the Sylvester series midrange drivers.

Two DB 2-way filters v2 connect the midbass and tweeters in 2-ohm operation, with a crossover frequency at 4000 Hz (12 dB/oct) and three-stage tweeter attenuation (0, -3, -6 dB) for fine-tuned balance and control.

Everything is mounted in a dBVox Raggarplanka Slope Style – made of solid MDF, covered in black carpet and embroidered with the LOUD AS HELL logo. Four 6.5" slots, two tweeter positions, and a side-mounted terminal make the installation simple and reliable.

AP-M60SQL 4x6.5 LOUD AS HELL Plank Slope V3 is the choice for those who want the musical soul of the Sylvester series combined with SPL strength, topped off with high-end tweeter precision – in a package built to dominate both the road and the show.

NOTE! Sold as a DIY kit.
The tweeter holes in the enclosure may be smaller than the delivered tweeters. This is to allow compatibility with most tweeters in the included universal enclosure. You may need to use a rasp or similar tool to widen the hole for a perfect fit.
