Smooth Speed & Slam
Continuous Cast™ Cone Bass Engine
S/5 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 entire system.
Sound Beyond Its Size
Carbon Passive Radiator
S/5 SHO uses a special carbon/carbon passive that is stiff, lightweight and incredibly well-behaved. Our approach to passive design results in performance more akin to a variable ratio driver size. On an S/5 SHO, think of it as a sliding ratio design wherein the S/5 SHO begins as an ultra-fast 12” sealed box design and, as more power and deeper bass is demanded, the S/5 SHO gradually morphs into the power and output of a 15” design.
Fast, Extended Lows
NextGen2 550W Digital Amplifier
Beyond our proprietary drivers, the performance of a REL is determined by our unique input filters and amplifiers. S/5 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. 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.
S/5 SHO’s power amplifier is a powerful NextGen2 550W 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.
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.
As a long-time audiophile, I had been of the opinion that subs were not meant for, nor were they capable of improving in any way, a high quality 2 channel audio set up. I was wrong, and had no idea how much I was missing out on. I've purchased a pair of S/5 SHO last year and have integrated them into my 2 channel set up that's being powered by Parasound JC1 mono-blocks and I could not be happier. Not to sound cliche, but the improvement is dramatic in not just the lower bass frequency, but the mids and highs as well. In fact, when tuned correctly, you don't know that a subwoofer (or a pair of them in this case) is in place. It's seamless. The resulting improved soundstage is the first difference I noticed, as well as the more articulated mid and highs. Who knew? Now I do, and I can't convey enough how impressed I am and how much they added to my system and my enjoyment of music from it.
I purchased a pair of these to go with a pair of monitor Audio gold 300 series 5 speakers.
I thought I had a good system before with old Velodyne Optimus 12 sub’s. Not even close. You hear the whole base line with a lot of subtle bass runs you can’t hear without this sort of equipment.
I think this is very good value.
I have a pair of S/5 SHO. I purchased them about 3 months ago so plenty of time to form an opinion. I have owned other subs from some well know speaker suppliers and never thought they were as well suited for music as they were for home theater. The need to blend in seamlessly with home theater is not that critical but for music it is. These subs have brought my system to a whole new level and are easy to adjust to get them to disappear and seem to be part of the main speakers. If you are a person seeking to get the most out of 2 channel music and these fit your budget you cannot go wrong. You do need a good size room. Mine is 14 x 21 and they are great. I run a pair of Primaluna EVO 400 amps, EVO 400 preamp with an EAT C Sharpe turntable, + EGlos Preamp from EAT plus a pair of Klipsch RF-7III speakers. It sounds pretty good. To go to the next level will require about 15K in speakers. That's down the road.
Outstanding addition to a full range speaker. Super quick, powerful bass. This sub will just disappear. Suggest using the high output connection. Easy installation and set up. Highly recommended!
This is a wonderfully musical sub. I've owned many subs (including my last one-a REL B-2), and this one is a wonderful value. I've been a fan of the Neutrik connector since the B-2, but the S-5 adds separate volume controls for x.1 input as well as the Neutrik connection. Spend the time to set up your system for music and surround sound-you'll be richly rewarded.

"linearity and bass extension mean nothing if there are no dynamics, and here the REL S5 completes the hat trick of sub-bass virtues, because its dynamism is infectious in the same way a great rhythm simply forces you to move your feet. With the S5, the dynamics likewise force you to become totally involved with the music… there’s not a single one of your senses that is not totally engaged with whatever is playing" Read More +
Greg Borrowman, Audio Esoterica
"The S/5 SHO is a bigger sub than the S/3 in every respect, sounding heftier, bolder and more fulsome. I’m not sure I could detect any real difference in its lowest frequency response, but the S/5 certainly made its LF presence felt more in your chest. Gary Oldman’s opening scene in the Leon SE Blu-ray (part of the revamped Luc Besson collection) is a dynamic tapestry of silences and spectacular impacts that demands the very best sub performance. From Oldman’s 'I like these calm little moments before the storm' line to the opening shotgun blasts, the S/5 delivers plenty of its SHO promise." Read More +
Richard Stevenson, Home Cinema Choice
"Thankfully for bass fans everywhere, nothing has changed in its latest venture, the S/5, which may be the best-performing midpriced sub REL has offered in its vaunted history. The S/5 goes about its tasks so matter-of-factly, effortlessly, and invisibly that it seems to become another attractive fixture in the room—until you pull it from the system. Then you understand what authentic low bass brings to the party. You also begin to understand the meaning of…addiction." Read More +
