REL Acoustics S/812 Subwoofer


A high-end sub that oozes style and charm. The S/812 delivers deep and controlled bass that’s handled with speed and agility, seamlessly blending with the other speakers in your system to create a fully integrated soundstage.


The most dramatic upgrade to any mid-line REL ever.

Upscale's best-selling subwoofer models, the beloved REL S/3 SHO and S/5 SHO have been given a complete transformation into the new Serie S. The beautiful new cabinetry is contrasted by subtle gunmetal grey badging, and the feet have been replaced by ultra-stable rails, reflecting proportions from REL's reference portfolio.

The S/812 uses the 212/SE's NextGen3 amp electronically limited to 800 W with peaks in excess of 1,000 W. The increased power is needed to handle the special filters first used in the HT/1508 that offer almost twice the output below 40 Hz for .1/LFE applications. 

The high- and low-inputs use a new design called PerfectFilter that offers a more musically natural performance with more air and openness. The already ultra-light driver cone from the original Serie S has been upgraded with a rear-mounted carbon fiber bracing that stiffens and deadens the cone almost 60% more than the original. Improved filtering results in greater speed, delicacy, and precision, offering a powerful and extremely flat response.

Finally, these are the first medium-chassis RELs designed to be stackable up to three units high on each side. This opens up the awe-inspiring scale of REL's Reference Line Arrays to a whole new audience.
