The REL S/5 exceeds the mandate for mid-level models and crosses this model into true reference quality. S/5 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 and grand theaters are ideal. Medium to grand rooms are appropriate. Scale is Very Large, Speed is Exceptional, Attack and Slam is Visceral.

Smooth Speed & Slam

Continuous Cast? Cone Bass Engine

S/5'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 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, think of it as a sliding ratio design wherein the S/5 begins as an ultra-fast 12" sealed box design and, as more power and deeper bass is demanded, the S/5 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. REL S/5 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 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'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.

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). 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.
