Invisible Upgrades to S/812’s Bass Engine
Pure Carbon Fiber Backing
S/812 required upgrades to its ContinuousCast™ Alloy Cone to allow it to survive the massive power upgrades. To permit its thin, aluminum cone to survive 800 watts and incredibly long stroke, we added an ultra-lightweight backing of pure carbon fibre, strategically placed over portions of the rear surface of the cone. This produces two benefits; it strengthens and stiffens the cone and also eliminates reversion, wherein the backwave inside the cabinet is now prevented from interfering with the main launch of bass into the room. The result is more accurate and far louder deep bass.
There is Nothing Passive About These
Carbon Passive Radiator
Our uniquely tuned passive radiators use special suspensions, now with an additional 30mm of linear travel, to produce performance far beyond conventional subwoofers. Our new SuperProgressive™ passive radiator produces extremely long travel allowing for very loud output while retaining the variable stiffness of its suspension. This allows it to act like a sealed box compact 12” design at low volume and a high output 14” design at its limit.
Warning: Power Amplifier on Steroids
800 watts and Counting
At 800 watts the NextGen 5 amplifier is borrowed from our reference models and rocks huge reservoirs of power and current. The 45% increase in power (previous version was 500 watts) is needed to deliver both the profound output levels needed for modern theatre, as well as to produce the deepest bass in a high end 2-channel system. This increase in power is necessitated by our development on the musical front of an all-new circuit termed PerfectFilter™ that balance both frequency extremes.
PerfectFilter performs two seemingly disparate qualities; extending the strong, even response of the extreme low end of bass frequencies while simultaneously opening up air and delicacy in the middle and high frequencies of one’s system. Additionally, we applied customized PureTheatre™ filters to allow S/812 to deliver the most awe-inspiring theatre effects ever offered in a classic REL.
Serie S Line Array
Stacked for Ultimate Performance
In the real world, bass occurs with width, depth and height. By stacking up to three units per side (stereo or theatre main L-R speakers) the proper perspective and height of sonic events are illuminated. This elevates reproduction from conventional stereo or theatre to a floor-to-ceiling panoramic, full scale perspective of each sonic event. Reviewers are lining up to marvel at the transformation of music and film into the full-scale representation that REL Line Arrays uniquely deliver.
Reviews + Awards
There are plenty of cheaper subs, and some can even go nearly as deep as the S/812, but they’re unable to mine such depths while remaining so composed. Good bass shouldn’t dominate, it should be an integral part ofyour cinema soundstage, adding low-frequency impact where needed. This is what the REL S/812 achieves so well – it goes deep with control, shows effortless speed and agility, and can seamlessly blend with your other speakers to enhancing whatever you’re watching.

Home Cinema Choice Best Buy Award
"This is an excellent subwoofer that's beautifully designed and fantastically well made. It's also an impressive performer, delivering exceptional bass in a tight and controlled fashion. The combination of the 12-inch driver and matching 12-inch passive radiator ensures some serious low-end extension, and the amplification has power to spare." Read More +
Best High End Subwoofer 2020
The REL S/812 is a genuinely impressive subwoofer that manages to combine low-end extension with powerful amplification to produce a performance that’s responsive, controlled and highly effective. This sub goes deep and, even on its own, had absolutely no trouble filling my home cinema with low frequency energy. However, this is no blunt instrument, and the S/812 is capable of astonishing deep bass that’s delivered with a surprising amount of subtlety and grace. Read More +
