S/510
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.

“Between having the RELs on and off, the difference was huge. There was much more body and soul to the singers voice with the RELs, much more overall presence to the music, more grandiose in scale, and overall more fullness, warmth and richness to everything.” Read More +

Editor’s Choice Award
“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.” Read More +
Home Cinema Choice Best Buy Award
“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.” Read More +
Outstanding Product
“Whether you opt for a single S/510 or a pair in stereo, for the money, and in my opinion and experience, there isn’t anything else out there that will perform as admirably and REL’s reputation precedes them” Read More +
HiFi Pig Outstanding Product Award
“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 +
