REL S/3 Details

REL S/3 Subwoofer: Power and performance
  • 10-inch, Continuous Cast Alloy, long-throw, front-firing active woofer
  • 12-inch, Carbon, down-firing passive radiator
  • 400-watt (RMS) digital amplifier
“Although it can happily shake the walls every bit as much as its R328 predecessor, this is also a subtle and deft device. It just adds more depth to the bass and control to the upper registers. I’ve become something of a convert!”
    Hi-Fi Plus

The REL S/3 Powered Subwoofer is derived from the company’s flagship S/5 model. It offers much of the S/5’s performance but with a more compact footprint, for use with slightly more modest systems and/or rooms.

Powerful, incisive and beautifully balanced performance
The S/3’s driver features an all-new alloy cone structure that takes REL’s mid-level product to a performance that exceeds their 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, REL’s engineers were able to increase the self-quieting key to a high-end component’s ability to resolve space and inner detail.

Sound beyond its size with a carbon passive radiator
S/3 uses a special carbon/carbon passive radiator 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/3, think of it as a sliding ratio design wherein the S/3 begins as an ultra-fast 10-inch sealed box design and, as more power and deeper bass is demanded, gradually morphs into the power and output of a 15-inch design.

Fast, extended lows with NextGen2 400W digital amplifier
Beyond the proprietary drivers, the performance of a REL sub is determined by the company’s 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 our driver. This speed and our 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 our new driver.
