Reproduce Difficult-to-Render Instruments and Passages With the REL S/5 SHO Subwoofer: Super High Output Flagship Boasts 15-Inch Cast-Alloy Driver, 550W Digital Amplifier
The S/5 SHO subwoofer, the recently re-engineered Super High Output flagship of REL's Serie S specializes in reference-grade reproduction of the most difficult-to-render musical instruments and low-end passages. At home even in large two-channel and palatial home-theater setups, S/5 SHO possesses cheetah-like speed, visceral attack, tremendous slam, massive scale, and pinpoint refinement. REL's 15-inch Continuous Cast Cone bass engine, special carbon/carbon passive radiator, and super-powerful 550W digital amplifier round out this landmark design. If you think you've heard all your music has to offer, S/5 SHO will come as a pleasant revelation.
"In the Serie S, driver and amplifier engineering have created a new benchmark."

Double the Output and Performance of Its Predecessor
S/5 SHO's 15-inch Continuous Cast 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 two-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 three-stage limiter REL 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.
New Alloy Cone Structure Exceeds Reference Standards Set Just a Few Years Ago
S/5 SHO's driver features an all-new alloy cone structure that generates performance that exceeds reference products of only a few years ago. By reducing moving mass and adhering to a balanced approach to design, REL's engineering team produced far more speed than prior designs. By carefully adjusting key parameters, REL increased the self-quieting key to a high-end component's ability to resolve space and inner detail.
Carbon Passive Radiator Allows for Sliding-Scale Behavior
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-inch sealed box design and, as more power and deeper bass is demanded, S/5 SHO gradually morphs into the power and output of a 15-inchdesign.
NextGen2 550W Digital Amplifier Yields Fast, Extended Lows
Beyond proprietary drivers, the performance of a REL is determined by 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 carefully sorted filters allow for seamless blending of RELs with the main speakers. REL does 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 500W 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 the new driver.
Wireless Freedom: LongBow Connectivity
LongBow permits very fast, uncompressed bass to be sent wirelessly within the same room approximately 45 feet (somewhat dependent upon room clutter). REL selected an uncompressed format as it results in natural, quick delivery compared with conventional wi-fi or Bluetooth systems. REL developed LongBow with both high level (or low level with crossover intact) AND .1 channel delivery so that REL Theatre Reference performance can be maintained even when using the wireless delivery system.
