REL Acoustics S/510 Subwoofer

Only %1 left
The REL Acoustics S/510 Subwoofer provides your speaker system with powerful and controlled bass, with a 10 inch driver coupled with a 12 inch downfiring passive driver for extra bass extension. Containing 500W of power, the S/510 sub blends with your main speakers to bring all your music and movies to life.

The S/510 subwoofer contains improved and updated technology compared to the previous generation, to extract all the extra performance possible. The S/510 produces stronger deep bass output from 20-35Hz, with improved dynamics for home cinema and a more open, spacious sound field to benefit music and movies.

The S/510 uses an aluminium ContinousCast alloy cone, backed with carbon fibre for a strong and stiff driver, to cope with the pressure produced from the 500W amplifier. The long throw driver creates louder deep bass with far more accuracy, by preventing the backwave inside the cabinet from interfering.

The passive downfiring driver on the S/510 uses specially designed suspensions, with an additional 8mm of travel for a performance beyond standard subs. The SuperProgressive passive radiator produces a loud output while retaining speed and stiffness.

The NextGen3 Class D amplifier supplies the S/510 with 500 Watts of power, along with high current to make sure the subwoofer is ready for any media. Music and movies are more immersive and inspiring with powerful yet controlled bass. With a new PerfectFilter circuit to balance the frequency extremes, producing deeper bass and more air and delicacy in the top end, the S/510 seamlessly blends with your main stereo or AV system speakers.

The REL S/510 sub also benefits from REL’s Line array, by stacking up to three units high in a stereo pair, to produce a full scale performance in a previously unheard-of sonic arrangement. This unique configuration elevates reproduction of stereo or home cinema to a floor-to-ceiling panoramic. The S/510 can also be used wirelessly with the REL AirShip wireless transmitter for zero compression signal, allowing you to easily place the subwoofer anywhere in the room without the need for cables.
