REL Acoustics LTD



A REL is a SYSTEM, hence the term Sub-Bass System. RELs are built like no others because it is quite difficult and costly to execute to our standard. As a pure high-end company, we believe in first doing no harm with our subs. So, we offer no high pass crossovers that interfere with the bass from the main speakers. This means we sell fewer subs, but the ones we do sell make their owners quite happy.

The REL Series S ~ 212/SE Sub-Base System

Introducing 212/SE, REL's most powerful and agile subwoofer, designed exclusively for larger system and rooms to allow superior state of the art speakers to spring to full voice. We believe in quality first, not simply power and boom.

QUALITY MEETS QUANTITY

REL believe 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.

 

The REL G-1 MkIISub-Base System

Gibraltar G-1 transforms the definition of deep bass for the home. We know of no finer ambient space and deep bass reproducer. G-1 combines shocking speed and clarity with formidable power handling and depth. G-1 combines a cabinet of remarkable complexity, with a power amplifier capable of sufficient current production to develop even the lowest, sustained passages–whether in ultra high-end home theater or the finest audiophile music system.

The massively beautiful, finned, alloy heatsink is necessary when dissipating the sorts of power necessary for prodigious deep bass for hours on end. Capable of outputting a conservative 600W (120V) on occasion, the dedicated REL Class A/B amplifier used in G-1 is a true dreadnaught. Powerful, fast and capable of tremendous current delivery, it is the finest amplifier ever designed by our engineers.

The 12" bass engine fitted to every G-1 features ultra light, stiff carbon fibre - the same stuff used to craft race car chassis - as weight goes down, speed goes up.

 

 

The REL Series S ~ S5/SHO Sub-Base System

S/5 SHO exceeds the mandate for mid-level models and crosses this model into true reference quality. S/5 SHO produces exceptionally low bass with tremendous impact and speed. Even difficult-to-render instruments such as pipe organs are dealt with effortlessly. Large scale, high end 2-channel systems make a perfect pairing for S/5 SHO and grand theaters are ideal. Medium to grand rooms are appropriate. Scale is Very Large, Speed is Exceptional, Attack and Slam is Visceral.

Beyond our proprietary drivers, the performance of a REL is determined by our unique input filters and amplifiers. REL 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. REL 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.
