Power and Performance
The REL S/3 subwoofer derives from the flagship S/5 and offers a more compact footprint and much of S/5 performance for use with either slightly more modest systems or rooms that cannot handle the power and output of S/5. Qualitatively, it is the equal of S/5, sans the grand scale, power and majesty of its larger sibling. Beautifully balanced, S/3 offers powerful, incisive and beautifully balanced performance.
"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!" – Nicholas Ripley, HiFi Plus
Smooth Speed & Slam: Continuous Cast Alloy Bass Engine S/3's driver features an all-new alloy cone structure that takes a mid-level product to a performance that exceeds reference products of only a few years ago. By reducing moving mass, with a balanced approach to design, REL's engineering team was able to produce 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. Improvements in these designs translate into enhancement in your entire system.
Sound Beyond its Size: Carbon Passive Radiator S/3 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/3, think of it as a sliding ratio design wherein the S/3 begins as an ultra-fast 10" sealed box design and, as more power and deeper bass is demanded S/3 gradually morphs into the power and output of a 15" design.
Fast, Extended Lows: NextGen2 550W Digital Amplifier Beyond proprietary drivers, the performance of a REL is determined by unique input filters and amplifiers. REL S/3 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/3'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 the new driver.
Freedom: LongBow Wireless 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.
