REL S/5 SHO Subwoofer

S/5 SHO (Super High Output) exceeds the mandate for mid-level models and crosses this model into near reference quality. S/5 SHO’s 15” Continuous CastTM Alloy Cone Driver and carbon passive radiator produces exceptionally low bass with tremendous impact and speed. Its NextGen2 550W digital amplifier makes large scale, high-end 2-channel systems and grand theaters a perfect pairing. Medium to grand rooms are more than appropriate as scale is very large, speed is exceptional, and attack and slam is visceral.

SHO refers to Super High Output, made possible by a new 3-stage limiter our engineers created after extensive testing revealed that much higher output, higher gain and higher performance could be unlocked. The result is a new design that is capable of more than doubling its predecessor’s output. Specify the S/5 SHO, singly or in pairs, when your system is of exceptionally high quality, and your speakers and room can support high levels of dynamics and bass extension.
