Product Overview:

  • The 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 S5 and grand theaters are ideal.
  • Scale is Very Large, Speed is Exceptional, Attack and Slam is Visceral.C

Continuous Cast™ Cone Bass Engine

  • S/5’s driver features an all-new alloy cone structure that takes RELs mid-level product to a performance that exceeds the 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, they were able to increase the self-quieting key to a high end component’s ability to resolve space and inner detail.
  • Improvements in their designs translate into enhancement in your entire system.

Carbon Passive Radiator

  • S/5 uses a special carbon/carbon passive that is stiff, lightweight and incredibly well-behaved.
  • Their 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.

NextGen2 550W Digital Amplifier

  • Beyond RELS proprietary drivers, the performance of a REL is determined by their 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 their new driver.

Freedom with LongBow™ Wireless Connectivity

  • LongBow permits very fast, uncompressed bass to be sent wirelessly within the same room approximately 45 feet.
  • We have selected an un compressed format as it results in natural, quick delivery compared with conventional wi-fi or Bluetooth systems.
  • REL has developed the 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 their wireless delivery system.
