The All New S/812

Shattering Performance Barriers

For S/812, every aspect of the previous generation’s inner workings were examined without regard to its critical and customer-driven success. We turned a fresh eye to power requirements, driver improvements, and specialty filters, upgrading each to extract all the extra performance possible. All this alongside the cabinet refinements necessary for those upgrades to emerge cleanly. This latest S range is a triumphant development that has exceeded every expectation of our design team.

Our requirements were for far stronger deep bass output between 19-35 Hz, vastly improved theatre dynamics, and an even more open and spacious soundfield which benefits both music and film. We turned to our NextGen5 amplifier, tuned to 800 watts, with huge reserves of power beyond this, added a light film of carbon fibre to the rear of the driver to handle the extra power, and developed two new sets of custom filters to extract the utmost in brute force and spaciousness. Finally, we imbued 812 with the ability to be stacked in 4- or 6-unit line arrays, just like our reference models.

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.

Passive Radiator

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 producesextremely long travel allowing for very loud outputwhile 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 NextGen5 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.

Unbelievable Sub

First I must say thanks to the entire Rel team who spent A LOT of time helping me understand their products and choose my new sub. I have Focal Sepora No.3 front speakers and needed a powerful sub to play with them. John helped my choose the S-812 and I could not be happier. The speed, accuracy, and definition make this an incredible find. I purchased 2 for a stereo sound, but had to return one secondary to damage and decided that I did not have the room for 2. John and Rachel were very helpful in first helping my decide if I should keep the 2nd sub and then the return process. I was going to place the 2nd across the room and use wireless technology, but Justin helped me understand the sound field would not be stereo and not what I was looking for. Please watch all the videos John put together and if you still have questions the support team, including John, will answer any and all your questions. Excellent company and excellent products.
