The Compact S/2 is Fast, Fun & Powerful
REL's S/2 subwoofer may be the least expensive, most
compact chassis in the S range, but it would be a mistake to think of it
as anything but a true thoroughbred. Fast, tuneful, fun and
exceptionally dynamic, S/2 permits those with limited space or compact speakers to enjoy the benefits of Serie S performance. S/2 offers a powerful 250W NextGen Class D amplifier
with a fast, lightweight driver and matching passive in a carefully
damped cabinet to produce bass that is quite extraordinary for such a
"The REL S/2 merges beautifully into my system, adding a
greater sense of scale and depth to tracks I thought I already knew. It

Snap & Attack: Anodized Aluminum Dustcap
S/2's driver receives a new purpose-designed anodized aluminum dustcap.
This both stiffens the cone structure, resulting in improved transient
response (snap and attack) while lowering the moving mass some 15%.
Careful tuning of this unit to cabinet volume and the new matching
downfiring passive driver results in outstanding performance for a model
of this size and price. Powerful, fast and tuneful is the S/2.
Clean Bass: Matching Passive Driver
REL's passive drivers are carefully matched to the active. In the case
of S/2, REL used the same driver as S/2 for a precise match, then tune
the resonant frequency a little lower to extend the bass performance
downward for a cleaner overall effect.
Seamless Sound: NextGen2 250W Digital Amplifier
Beyond the drivers, the performance of a REL is determined by the input
filters and amplifiers. REL S/2 uses a simple filter-type that is very
fast--about 8 milliseconds in group delay to get through to the driver.
This speed and carefully sorted filters allows for seamless blending of
RELs with the main speakers. S/2's power amplifier is a powerful
NextGen2 250W digital amplifier. This design has proven exceptionally
reliable and very fast with deep, extended lows--it provides a perfect
mate to its driver.
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). REL selected an uncompressed format as it results in natural,
quick delivery compared with conventional wi-fi or Bluetooth systems.
REL 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 the wireless delivery
