AirShip Wireless Connectivity – THE PURPOSE TO OUR PASSION

We have prided ourselves on our ability to deliver extremely high levels of sound quality and rock solid wireless connection protocols since our first wireless design over a decade ago. Airship surpasses any earlier design using a 5.8 gigahertz signal , a frequency previously reserved for military use by the US military and NATO. It results in the fastest, most transparent wireless the design team has ever experienced and verges on hardwired transparency level.

Ultra-high quality wireless confers a number of benefits to the REL owner, notably, freedom of placement. This permits extreme performance without the cumbersome tether of a cable, for ideal placement without being limited by the length of a wire, which can lead to a better sounding, less cluttered experience. So now you can place subs in distant corners, along glass walls, or on hardwood floors to ensure a superior experience, sonically and aesthetically.


REL Airship permits simultaneous use of our new 5.8 gig connection for both HIGH-LEVEL connection AND the .1/LFE needed for high quality theater. In this way, both 2-channel music and multi-channel theater are supported simultaneously, meaning you can use your REL for any form of music or theater without adjusting anything further .

Our High-Level input is designed to accept the stereo (two-channel) signals from the speaker terminals of your receiver, integrated amplifier or power amplifier(s). This has the advantage of ensuring that your subwoofer receives exactly the same signal as the main speakers, which means that the character of the bass from the main system is carried forward into our Sub-Bass System. Along with our extremely fast, natural sounding Filter Circuits, Airship ensures you receive the benefits of REL’s superior system integration since RELs are known the world over for their perfect, rich integration without the ability to sonically locate the subwoofer’s origin.

For top theatre performance, the .1/LFE circuit is granted its own dedicated wireless channel which allows for the largest, most dynamic special effects in theatre to be properly replicated in all their glory. Airship delivers 2 channels in parallel, one for music and theatre in High Level (or Low Level, increasingly needed for active wireless speakers for example) and a second channel for .1/LFE in theatre use.

When both are used correctly, normal theatre transforms because the cold, edgy sound most theatres deliver becomes rich and full-bodied. Dialogue and atmospheric effects take on new drama and realism because the full range of sounds are provided every moment of the movie by our High Level, whilst the .1 channel delivers extra emphasis during the 15-20 minutes of a movie that this channel is active. Truly the best of both worlds.


We designed and engineered Airship to deliver a simple, elegant pairing that operates as smoothly as it looks. Just plug both in within a few seconds of each other, push a button and the Airship seeks out its mating receiver and pairs with it. Standard time to pair is less than 5 seconds.


For many, the ability to listen to the highest quality of audio in glorious full range sound while placing their RELs perfectly for sound quality and best appearance has been a dream beyond their reach. Airship finally allows the final barriers between performance, placement and attractive room design to be replaced by a newfound freedom. Once experienced, you will never return to yesterday’s compromises.
