REL S/510 Subwoofer, Black

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. 
For S/510, every aspect of the previous generation’s inner workings were examined without regard to its critical and customer-driven success.

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.

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, 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. 
Uniquely tuned passive radiators use special suspensions, now with an additional 8mm of linear travel, to produce performance unlike conventional subwoofers. 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 inch design at low volumes and a high output 14 inch design at its limit.

At 500 watts the NextGen 3 amplifier is borrowed from 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 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. 

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.
