S/5 exceeds the mandate for mid-level models and crosses this model into true reference quality. S/5 SHO produces exceptionally low bass with tremendous impact and speed. Even difficult-to-render instruments such as pipe organs are dealt with effortlessly.Large scale, high end 2-channel systems make a perfect pairing for S/5 SHO and grand theaters are ideal. Medium to grand rooms are appropriate. Scale is Very Large, Speed is Exceptional, Attack and Slam is Visceral.
S/5 SHO’s driver features an all-new alloy cone structure that takes Rel’s mid-level product to a performance that exceeds Rel’s reference products of only a few years ago. By reducing moving mass, with a balanced approach to design, our engineering team was able to produce far more speed than prior designs. By carefully adjusting key parameters, Rel were able to increase the self-quieting key to a high end component’s ability to resolve space and inner detail. Improvements in their designs translate into enhancement in your entire system.
S/5 SHO uses a special carbon/carbon passive that is stiff, lightweight and incredibly well-behaved. Rel’s approach to passive design results in performance more akin to a variable ratio driver size. On an S/5 SHO, think of it as a sliding ratio design wherein the S/5 SHO begins as an ultra-fast 12” sealed box design and, as more power and deeper bass is demanded, the S/5 SHO gradually morphs into the power and output of a 15” design.
Beyond Rel’s proprietary drivers, the performance of a REL is determined by its unique input filters and amplifiers. REL S/5 SHO uses a simple filter-type that is very fast—about 8 milliseconds in group delay– to cross out unwanted higher frequencies to the+ driver. This speed and our carefully sorted filters allow for seamless blending of RELs with the main speakers. REL do not include a high pass filter to cross out bass from the main speaker because to do so would generally produce more unwanted effects than the minor benefits such a design confers.
S/5 SHO’s power amplifier is a powerful NextGen2 550W digital amplifier. This design has powered thousands of RELs and has proven exceptionally reliable and very fast with deep, extended lows—it provides a perfect mate to our new driver.
