Product Overview:

  • REL's most powerful and agile subwoofer, designed exclusively for larger systems and rooms to allow superior state of the art speakers to spring to full voice.

Quality Meets Quantity -The Powerful 212/SE

  • REL believes in quality first, not simply power and boom.
  • They believe that 1,000 watts is only desirable if it’s conveyed with speed and control.
  • Which is why the 212/SE was engineered to not only make your heart pound and walls shake, but restore midrange warmth and harmonic structure, while providing a powerful, rich low-end.
  • This combination of speed, power and grace driving multiple room modes (forward, down and rear) makes it ideally suited for high end 2-channel, grand rooms and dedicated theaters, allowing larger state of the art speakers to spring to full voice.

Double Down -Twin Continuous CastTM Alloy Bass Engines

  • To produce our highest output single-box solution, we doubled up on the Continuous CastTM Alloy Bass Engines that bring critical acclaim to Serie S, altering them slightly for this twin front-firing configuration.
  • These twin actives are responsible for 212/SE’s incredible speed and tactility.

Sound Beyond Its Size -Dual Continuous Cast Alloy Passive Radiator

  • The 212/SE uses two matching Continuous Cast Alloy passives that are stiff, lightweight and incredibly well behaved.
  • Our approach to passive design results in performance more akin to a variable ratio driver size – as more power and deeper bass is demanded, the passive comes to life, gradually expanding the capabilities of the active engines.

Command and Control - NextGen3 1,000w Digital Amplifier

  • Beyond our proprietary drivers, the performance of a REL is determined by our unique input filters and amplifiers.
  • 212/SE 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 gentle crossover slopes allow for seamless blending of RELs with the main speakers.
  • RELs 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.

Freedom - 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 uncompressed 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.
