Product Description

The top of the range in the Series S family of advanced sub bass systems from REL, the S5 is powerful enough to complement large speakers and large rooms. If that's still not enough, try two. Your music will love you for it. 


REL Series S takes the concept of audiophile quality components as furniture-grade companion to the sophisticated home to a new level. Because not everyone lives in the same sized house with identical speakers, REL offer two different levels of accomplishment (S3 and S5) that increase in quality, scale and refinement. Series S combines a higher performance level than REL have ever set out to deliver within their mid-level range, with ease of use and freedom from conventional restraint.

The Serie S Flagship - The Majestic S5: The S5 exceeds the mandate for mid-level models and crosses this model into true reference quality. S5 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 theatres 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: S5’s driver features an all-new alloy cone structure that takes this mid-level product to a performance that exceeds REL's reference products of only a few years ago. By reducing moving mass, with a balanced approach to design, the engineering team was able to produce far more speed than prior designs. By carefully adjusting key parameters, REL were able to increase the self-quieting key to a high end component’s ability to resolve space and inner detail. Improvements in the designs translate into enhancement in your entire system.

Sound Beyond Its Size - Carbon Passive Radiator: S5 uses a special carbon/carbon passive that is stiff, lightweight and incredibly well-behaved. The approach to passive design results in performance more akin to a variable ratio driver size. On an S5, think of it as a sliding ratio design wherein the S5 begins as an ultra-fast 12” sealed box design and, as more power and deeper bass is demanded, the S5 gradually morphs into the power and output of a very high-quality 15” design.

Fast, Extended Lows - NextGen2 550 Watt Digital Amplifier: Beyond the proprietary drivers, the performance of a REL is determined by the unique input filters and amplifiers. REL S5 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 the 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. S5’s power amplifier is a powerful NextGen2 550 Watt 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 for the new driver.

Bassline Blue: Although all REL Subwoofers are supplied standard with a Hi-Level Cable, REL also offer an upgrade Hi-Level Cable called Bassline Blue. This REL designed cable is the perfect way to improve the sound quality of your REL Subwoofer and in fact your entire system. The Bassline Blue cable is an upgrade every REL owner should investigate.

LongBow Wireless Connectivity: Freed from the need to snake ungainly audio cables across one’s salon, use of the optional LongBow Zero Compression Wireless Delivery Method produces two responses: utter amazement at the quality of sound (most wireless delivery systems destroy music’s warmth by compressing and expanding the sound digitally) and visual relaxation because, for once, there are no visible cables to detract from this experience.
