REL S/510 Subwoofer

Extreme Performance...COMPACT PACKAGE

For the S/510, REL carefully considered every feature of the predecessor's inner mechanisms and modified power requirements, enhanced drivers, and installed unique filters to gain as much superior performance as 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.

REL's requirements were for far stronger deep bass output between 20-35 Hz, vastly improved theatre dynamics, and an even more open and spacious sound field which benefits both music and film.

So they turned to the 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.  They also developed two new sets of custom filters to extract the utmost in brute force and spaciousness.

Finally, the S/510 has been imbued the ability to be stacked in 4- or 6-unit line arrays, just like REL's reference models.

Invisibly Upgraded

REL's S/510 Subwoofer needed upgrades to its ContinuousCast™ Alloy Cone to support its 500-watt power upgrades. To strengthen and stiffen the thin, aluminium cone for sustained output, REL added a backing of pure carbon fibre to portions of the cone's rear surface.

This eliminates reversion, while ensuring the backwave doesn't interfere with bass projection. This leads to a higher fidelity, more pronounced deep bass.

Nothing Passive About This

REL's uniquely tuned passive radiators use special suspensions, now with an additional 8mm of linear travel, to produce performance unlike conventional subwoofers.

The 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

At 500 watts the NextGen3 amplifier is borrowed from REL's previous 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.

REL also applied customised PureTheatre™ filters to allow S/510 to keep up with modern theatre effects without breaking a sweat.

Stacked for Ultimate Performance

In music and movie playback, bass frequency should be experienced with width, depth, and height.

When stacking up to three subwoofers per channel, the perception of sonic events is improved; taking the listening experience from a mere stereo or theatre setting up to a room-encompassing, three-dimensional realisation of each individual sound.

Critics are noting the transformation of sound when hearing through a REL Line Array, with the full-scale results garnering great admiration.
