REL HT-Air MKII Wireless Transmitter/Receiver - Black

REL HT-Air MKII Wireless Transmitter/Receiver – Black

Cut the cable, not the performance, with the REL HT-Air MKII Wireless Transmitter/Receiver. Designed specifically for REL Serie HT subwoofers, the HT-Air MKII gives you the freedom to place your subwoofer where it sounds best—without being limited by cable runs. Built for home cinema systems where deep bass and timing matter, it creates a fast, stable and uncompressed wireless connection that keeps impact, detail and low-frequency precision intact.

Whether you’re building a dedicated cinema room or refining your living room setup, the HT-Air MKII makes subwoofer placement easier while maintaining the performance REL is known for.

Wireless Freedom Without Sacrificing Bass Performance

Subwoofer positioning can make a huge difference to bass quality, but cable limitations often force compromises. The REL HT-Air MKII removes that restriction by creating a dedicated wireless link between your AV receiver or amplifier and your REL subwoofer.

This means you can position your subwoofer in the ideal acoustic location—whether that’s across the room, tucked into a corner or away from visible cabling—without trailing wires across the floor.

For many setups, this flexibility can result in cleaner bass response, better room integration and a neater overall installation.

Fast 5.8GHz Wireless Transmission for Real-Time Performance

At the heart of the HT-Air MKII is REL’s third-generation 5.8GHz wireless technology, developed specifically for subwoofer signal transmission.

Unlike standard Bluetooth or general Wi-Fi solutions, REL’s dedicated protocol is built to handle low-frequency effects with speed and stability. The result is:

• Fast signal delivery with approximately 17ms latency
• Uncompressed transmission for better bass accuracy
• Stable performance with reduced interference
• Strong dynamic response for films and music

This low-latency connection helps preserve the timing and punch of bass-heavy content, making explosions, soundtrack swells and deep effects feel more immediate and connected.

Purpose-Built for Home Theatre Systems

The HT-Air MKII has been engineered with home cinema in mind, particularly for the REL Serie HT Subwoofers range.

It supports both:

• LFE (.1) connections for AV receivers
• Low-level RCA connections for broader system compatibility

This makes it easy to integrate into most home theatre and AV systems, whether you’re running a dedicated cinema processor or a traditional amplifier.

For users building Dolby Atmos or surround sound systems, wireless subwoofer placement can make room planning much simpler.

Simple Plug-and-Play Setup

One of the strongest features of the HT-Air MKII is how straightforward it is to install.

There’s no app, no Wi-Fi network configuration and no password setup.

Simply:

1. Connect the transmitter to your AVR or amplifier
2. Connect the receiver to your subwoofer
3. Press the pairing button on each unit

That’s it.

Within seconds, the system is ready to go, making it ideal for users who want performance without complicated setup processes.

Helps Reduce Cable Clutter & Ground Loop Noise

Removing long RCA cables doesn’t just improve room aesthetics—it can also help eliminate practical audio issues.

Long subwoofer cable runs can sometimes introduce hum or ground loop interference, especially in complex AV systems. By going wireless, the HT-Air MKII can help minimise those problems while keeping installations cleaner and easier to manage.

This is especially useful in larger rooms where cable routing can become difficult.

Premium Acrylic Build Quality

REL has put genuine attention into the physical design of the HT-Air MKII.

The transmitter and receiver are housed in solid acrylic enclosures finished with multiple layers of hand-applied lacquer, giving them a premium gloss-black appearance that complements REL’s subwoofer range.

The heavier casing isn’t purely cosmetic—it helps stabilise the unit when connected with thicker interconnect cables, reducing movement and keeping connections secure.

It’s a thoughtful design detail that reflects REL’s performance-focused engineering.

Strong Wireless Range for Flexible Placement

The HT-Air MKII is designed to deliver reliable signal transmission over distances of up to 12 metres (40 feet) in typical environments, with the potential for even more range in ideal conditions.

This makes it practical for:

• Larger living rooms
• Dedicated cinema rooms
• Open-plan spaces
• Difficult cable-routing layouts

You gain more freedom to optimise bass placement based on room acoustics rather than cable reach.
