Product Overview:

Beautifully balanced, S/3 offers powerful, incisive and beautifully balanced performance.

Continuous Cast™ Cone Bass Engine

  • The S/3’s driver features an all-new alloy cone structure that takes REL’s mid-level product to an all new level of performance.
  • 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 has been 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.

Sound Beyond Its Size

  • It 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 S/3, think of it as a sliding ratio design wherein the S/3 begins as an ultra-fast 10” sealed box design
  • As more power and deeper bass is demanded S/3 gradually morphs into the power and output of a 15” design.

Fast, Extended Lows

  • Beyond REL’s proprietary drivers, the performance of a REL is determined by their 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 the 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 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 a 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.
