THE NEWLY REENGINEERED SHO SUPER HIGH OUTPUT
“Although it can happily shake the walls every bit as much as its R328 predecessor, this is also a subtle and deft device. It just adds more depth to the bass and control to the upper registers. I’ve become something of a convert!”
S/3 SHO derives from the flagship S/5 SHO and offers a more compact footprint and much of S/5 SHO performance for use with either slightly more modest systems or rooms that cannot handle the power and output of S/5 SHo. Qualitatively, it is the equal of S/5 SHO, sans the grand scale, power and majesty of its larger sibling.
Beautifully balanced, S/3 SHO offers powerful, incisive and beautifully balanced performance.
S/3 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 yourentire system.
S/3 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/3 SHO, think of it as a sliding ratio design wherein the S/3 SHO begins as an ultra-fast 10” sealed box design and, as more power and deeper bass is demanded S/3 SHO gradually morphs into the power and output of a 15” design.
Beyond our proprietary drivers, the performance of a REL is determined by our unique input filters and amplifiers. REL S/3 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. 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/3 SHO’s power amplifier is a powerful NextGen2 400W 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.
LongBow permits very fast, uncompressed bass to be sent wirelessly within the same room approximately 45 feet (somewhat dependent upon room clutter). We have selected an un compressed format as it results in natural, quick delivery compared with conventional wi-fi or Bluetooth systems. Because it is a REL, we 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 our wireless delivery system.
