“In both subtle and not so subtle ways the REL S/5 completed every speaker system it partnered with. Ultimately, it’s up to every audiophile to ask himself whether he wants the whole musical picture—the entirety of the soundscape. If your answer to that question is an unqualified yes, then consider yourself warned: Don’t even think of plugging in the S/5 if you ever expect to use that outlet again. An exceptional performer in any class.”
    — Neil Gader,The Absolute Sound
The REL S/5 subwoofer exceeds the mandate for mid-level models and crosses 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 are perfect for S/5, as are grand home theaters in medium to large rooms are appropriate.

Smooth speed and slam from the Continuous Cast™ Cone Bass Engine
S/5’s driver features an all-new alloy cone structure that takes REL’s 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, they were able to increase the self-quieting key to a high end component’s ability to resolve space and inner detail. Improvements in subwoofer design translate into enhancement in your entire system.

Carbon passive radiator helps create sound beyond its size
S/5 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, think of it as a sliding ratio design wherein the S/5 begins as an ultra-fast 12-inch 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-inch design.

NextGen2 550W Digital Amplifier
Beyond the proprietary drivers, the performance of a REL is determined by 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 the 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). REL’s engineers selected an uncompressed format as it results in natural, quick delivery compared with conventional wi-fi or Bluetooth systems. Because it is a REL, LongBow has 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 this wireless delivery system.
