The NEW S/5 SHO - THE SERIES FLAGSHIP

S/5 SHO represents the pinnacle of mid-level sub bass systems, combining our most innovative engineering to produce reference-quality sound in a stunningly sophisticated package.

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 12” 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.

Smooth Speed & Slam
CONTINUOUS CAST™ CONE BASS ENGINE

S/5 SHO’s driver features an all-new alloy cone structure that takes our mid-level product to a performance that exceeds our 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, we were able to increase the self-quieting key to a high end component’s ability to resolve space and inner detail. Improvements in our designs translate into enhancement in your entire system.

Sound Beyond Its Size
CARBON PASSIVE RADIATOR

S/5 SHO uses a special carbon/carbon passive that is stiff, lightweight and incredibly well-behaved. Our 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.

Fast, Extended Lows
NEXTGEN2 550W DIGITAL AMPLIFIER

Beyond our proprietary drivers, the performance of a REL is determined by our unique input filters and amplifiers. 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 our driver. This speed and our carefully sorted filters allow for seamless blending of RELs with the main speakers. RELs 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.
