Bundle Options

HT-Air MKII continues REL’s relentless drive to deliver the highest performance, the finest craftsmanship, and the easiest to use subwoofers available. With HT-Air MKII, we’ve outdone ourselves. Within seconds of plugging in the transmitter and receiver, you’ll be ready to start transmitting music or film audio at 5.8 gigs, completely free of digital compression, for the widest dynamics and best sound. HT-Air MKII delivers the highest performance for Low Level (RCA-RCA) or LFE/.1 (single RCA) transmissions.

Designed for Excellence

Design takes on new significance when it elevates commonplace items to a higher level. So it is with HT-Air MKII’s weighty, cubic wireless design that reinterprets the world-class form vocabulary of REL subwoofers and brings it home to everyday users. HT-Air MKII is built into a cast acrylic case that announces its quality at first heft. It’s not heavy for effect, we know that many owners will want to combine it with quality interconnects to obtain the best possible sound, and those cables can, themselves, be weighty. We‘re enthusiasts ourselves, so we designed the extra mass to ensure that choosing the wireless route wouldn’t lead to annoyance. Just one more way we let you know that we “get it”. Finally, we finished it off with 5 coats of hand-applied acrylic lacquer. What, you thought that deep glossy black came about by accident? Quality is in our DNA.

Prepare to Fall in Love with REL Pairing

We pride ourselves on having always designed and built the simplest, easiest-to-use wireless systems in the industry. Just tap a button on the transmitter and, once it begins blinking, tap the matching button on the receiver. That’s it! REL HT-Air MKII comes with all the internal programming installed and ready to go because we are not using conventional WI-FI. Our own dedicated protocol allows us to eliminate all the nonsense. Because when we get a new toy home, we want it to work now.

Wireless Is Freedom

HT-Air MKII employs our 3rd generation 5.8 GHz chip, our most advanced single-chip solution. It’s designed to allow continuous real-time streaming of music and movies. Featuring either L-R stereo inputs OR (1) .1/LFE input, the HT-Air MKII is easily capable of sending dynamic, rich-sounding sub-bass signals at least 40’ (12M) and, in ideal cases, even further. Like our more expensive models, it delivers a lightning-fast response of around 17 ms. That speed translates to better sound, greater dynamics, and performance nearing that of high-quality cables.
