Freedom of Placement

Subwoofer placement has a significant impact on bass performance, but the ideal acoustic position is not always convenient for cable routing. The REL HT-Air MKII removes this constraint by providing a reliable wireless connection between your AV receiver or processor and your REL HT subwoofer.

Without the need to run long RCA cables across the room, you can position your subwoofer where it performs best acoustically while maintaining a clean, discreet installation.

Designed for Home Cinema

Unlike general-purpose wireless audio solutions, the HT-Air MKII has been engineered specifically for home cinema applications. Operating on a dedicated 5.8 GHz radio frequency, it delivers stable, low-latency transmission capable of reproducing demanding LFE effects with excellent timing and precision.

The system supports the fast transient response required by modern Dolby Atmos and DTS:X soundtracks, ensuring explosions, bass effects and dynamic movie scenes retain their full impact.

Simple Plug-and-Play Installation

Installation is straightforward. Connect the transmitter to your AV receiver, surround processor or subwoofer output using a standard RCA connection, then connect the receiver directly to the compatible REL HT Series subwoofer. Pairing is automatic and requires no network configuration or software.
