REL S/3 SUBWOOFER

 

It may seem like a paradox, but the way to get good sound out of a subwoofer (for music use, at least) is to try to get almost no sound out of the subwoofer at all. Most stereo systems do not have an LFE/subwoofer line level output, but even if the system does include a line-level out for a subwoofer, REL recommends that for musical use, one is best served by connecting the subwoofer to the loudspeaker terminals (the REL takes a wired or wireless feed from the left and right positive and one negative speaker terminals at the amplifier). Then, reduce the output of the subwoofer until it becomes all but inaudible, and merely provides additional bass reinforcement below the limits of the loudspeakers. The process is more complex in the real world, but the important factor is the subwoofer should be ‘sub’; that is, it should play at a level and a frequency below the main loudspeakers, and subservient to their output.

The effect is that it does not necessarily enhance deep bass, but better control room interaction, thereby making the loudspeakers appear more free and open in the midrange. This is somewhat counter-intuitive, and you might expect a good subwoofer to provide extra authority and depth to deep bass notes and not much more. While the S/3 does help considerably here, its James Blunt rather than James Blake that gets the true benefit. While the original Back to Bedlam album is victim of intense overplaying by the mass media, Blunt’s live Chasing Time: The Bedlam Sessions [WEA] is a very well produced live album. While a singer-songwriter might seem far removed from subwoofer-land, the REL’s underpinning creates better stereo separation, more of a sense of a live performance, and instruments precisely located within that stage.

So far, this could apply equally to almost any correctly set-up REL subwoofer produced in the last 25 years. What the S/3 additionally provides is an even faster transient response, which frees up those middle and upper registers still further. While not a substitute for room acoustic treatment, the S/3 works like an active bass trap, but can also provide that bass depth needed when playing something like the ‘operatic’ version of West Side Story [DG], to best render all those foot stomps and stage directions. This is a tough test for a subwoofer, because it requires great depth and great speed, and the S/3 does both well.

Although it can happily shake the walls every bit as much as its R328 predecessor, this is also a subtle and deft device. The curious thing about the REL S/3 is its lack of impressiveness is what will impress you most. This subwoofer has little or no character to speak of and will interact with the fastest of loudspeakers with ease. You’ll hardly notice it is there, until you turn it off. Then, it’s like someone deflated your loudspeakers. Outstanding.

 

Power and Performance

The Beautifully Balanced S/3

S/3 SHO derives from the flagship S/5 SHO and offers a more compact footprint and much of S/5 SHO performance for use with either slightly more modest systems or rooms that cannot handle the power and output of S/5 SHo. Qualitatively, it is the equal of S/5 SHO, sans the grand scale, power and majesty of its larger sibling.

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

 

Smooth Speed & Slam

Continuous Cast Alloy Bass Engine

S/3 SHO’s driver features an all-new alloy cone structure that takes our mid-level product to a performance that exceeds our reference products of only a few years ago. By reducing moving mass, with a balanced approach to design, our engineering team was able to produce far more speed than prior designs. By carefully adjusting key parameters, we were able to increase the self-quieting key to a high-end component’s ability to resolve space and inner detail. Improvements in our designs translate into enhancement in your

 

Fast, Extended Lows

NextGen2 400W Digital Amplifier

Beyond our proprietary drivers, the performance of a REL is determined by our unique input filters and amplifiers. REL S/3 SHO 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 SHO’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.

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 un compressed 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.
