Soundmax SX-MX62BN LOUD AS HELL 4x6.5" SPL-Board Slope – Complete system with extra power and clarity
LOUD AS HELL SPL-Board Slope combines four Soundmax SX-MX62BN midrange speakers with two Soundmax SX-TA23 bullet tweeters in a robust and sealed angled board. The result is a complete system that delivers powerful midrange and crystal-clear highs with high efficiency and precision.

Four 6.5" Soundmax SX-MX62BN midrange speakers
With a power handling of 140W RMS (280W max) and a sensitivity of 93 dB, the SX-MX62BN are built to deliver clean and dynamic sound. They cover a wide frequency range from 100 Hz to 15 kHz, providing both punch in the upper bass and detail in the midrange. The robust 4.33" magnet provides control even at high sound levels, while the compact mounting depth of 65 mm makes installation easy.
Two Soundmax SX-TA37 bullet tweeters
The included tweeters enhance the overall sound with a frequency range of 3,000–20,000 Hz and a sensitivity of 105 dB. With a power handling of 140W RMS (280W max) and a compact design, they are perfect for systems that need to deliver clarity in the upper frequencies even at high sound levels.
LOUD AS HELL SPL-Board Slope
The board itself is built from heavy-duty MDF with a sealed angled design for optimal sound dispersion. The terminal is located on the side for easy connection, and a dividing wall in the center provides stability and controlled acoustics. The black carpet features an embroidered LOUD AS HELL logo on the back, giving it an exclusive and powerful appearance.
A complete package for high volume and precision
With four powerful SX-MX62BN midrange speakers, two crisp SX-TA23 tweeters and a robust LOUD AS HELL SPL-Board, you get a complete system that delivers punch, clarity and a massive soundstage. Perfect for car audio builds, A-tractors or any project where high sound levels are a must.
NOTE! The package is sold as a DIY kit
The enclosure's tweeter holes may be smaller than the supplied tweeters. This is to allow most tweeters to be used with the included universal enclosure. Therefore, a rasp or similar tool may be required to enlarge the holes for a perfect fit.
