Serie S

S/510 takes REL’s compact-medium chassis concept to reference-like levels of performance and does so with style, power and incredible speed. It delivers incredible levels of all ‘round performance. S/510 allows those with less space, or when pairing with high end speakers that are slightly less robust to have a perfect dance partner when the S/812 is simply too much of a great thing.

Extreme Performance

Compact Package

For S/510, 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 20-35 Hz, vastly improved theatre dynamics, and an even more open and spacious soundfield which benefits both music and film. We turned to our NextGen3 amplifier, tuned to 500 watts with substantial reserves of power, 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 S/510 with the ability to be stacked in 4- or 6-unit line arrays, just like our reference models.

Invisibly Upgraded

S/510’s Bass Engine

S/510 required upgrades to its ContinuousCast™ Alloy Cone to allow it to survive its massive power upgrades. To permit its thin, aluminum cone to survive 500 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.

Nothing Passive About This

SuperProgressive™ passive radiator

Our uniquely tuned passive radiators use special suspensions, now with an additional 8mm of linear travel, to produce performance unlike 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 volumes and a high output 14” design at its limit.

500 Watt Monoblock Within

NextGen3 Amplifier

At 500 watts the NextGen3 amplifier is borrowed from our former flagship model and produces huge reservoirs of power and current. The 20%+ increase in power (previous version was 400 watts) is needed to deliver the high output levels needed for modern theatre, as well as to produce the extremely deep 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/510 to keep up with modern theatre effects without breaking a sweat.

Stacked for Ultimate Performance

Serie S Line Arrays

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

“What makes the sound so well-focussed and precise with voice and bass, extends to a complete band or a whole orchestra .controlling the sound of the rest of the system with a benign, yet, iron authority.” Read More +


"With the S/510 I found a few more quieter spaces in the music as if it was truer to the acoustic space and more refined in how it allowed the synergy of itself and the main speakers to behave in a more three-dimensional manner, dealing with layers more intelligently."


HiFi Pig

“The S/510 digs deep and has the power and speed to delight with up tempo tracks and a subtlety that heightens engagement when the music demands. It’s inclusion adds scale and makes listening fun, which is really what it’s all about after all” Read More +

Hi-Fi Choice

"REL's 10in Serie S model doesn't have the spec-sheet power or depth of the larger and more expensive S/812, and this is apparent during single-model playback, but it comes very close and if anything it’s faster and more responsive. If you’ve got the budget, a pair of these smaller units will deliver a balanced and composed low-frequency foundation that can give your favourite movie moments some serious slam and an epic amount of scale."

Home Cinema Choice

"The REL S/510 manages to achieve the seemingly impossible task of squeezing a quart into a pint pot, without either shattering the glass or making the outcome not worth the effort." Read More +

"The detail and texture in the lower frequencies, along with the sheer weight that the six pack of S/510 provide is always what keeps me coming back for more music, for a longer listening session." Read More +
