Designed for Elegance
Design Many don’t realize the intense linkage between performance and design here at REL. Performance is everything to us and so it drives physical design revisions. Our engineers, recognizing the need for greater acoustic volume to achieve the goals of greater fluidity and power, turn to the designer who works dimensions to fool the eye into seeing a smaller, more compact footprint even though cabinet volume increases. Using gently rounded corner radii that allows the eye to flow over and see less visual mass. The result is both modern and familiar with no unnecessary adornment.

Faster & Deeper
Driver T/5x borrows a single longthrow 8” (200mm) bass engine from its elder sibling, T/7x. Developed using a composite of aluminum and light paper, this cone captures details that will amaze, while supplying sufficient energy to plumb deeper than one would expect for its size. In T/5x, its throw–the ability to play louder–has been increased. Internally, the suspension received numerous upgrades akin to transforming the handling of a car from a family sedan to a true sports car. More power, greater finesse.

Amplified Power
Amplifier T/5x builds on its predecessor’s reliable, expensive 125 W Class A/B amplifiers. Internally, key items significant to upgrading transparency and speed have been upgraded at no cost to REL’s legendary reliability. Separate inputs for High Level Inputs, Low Level Input (necessary for the increasing number of powered active speakers emerging on the market) allow for a natural, perfect transition from speaker to subwoofer. And in theater a separate, dedicated .1/LFE Input for Theatre performance permits automatic transition between music in high end 2-channel applications and home theater without needing to change a single setting. Magic? No, superior engineering. Standby Mode switch is only included on 220V units.

Zero Compression Wireless
Wireless At REL, we’ve developed a sterling reputation for building the finest sounding, fastest wireless systems available in the industry. REL never rely upon digital compression as it results in thin, lifeless sound. Instead, we have perfected an (optional) Arrow Wireless system; so fast and dynamic we’re comfortable encouraging the use of wireless on one channel of a pair of RELs while the other channel may be connected hardwired with cable.

"When something is good it's easy to describe in my opinion. So, I don't care what descriptor you want to use for sound quality, you can talk about integration, speed, articulation, bass note distinction, textures and so on. This thing is great, it's phenomenal. One of the best"

“The T/5x is a fabulous little subwoofer that grabs your attention for the sheer musical joy and engagement it brings to music. It represents one of the most effective upgrades I’ve heard to enhancing an audio system’s performance at the price.”
- Audiograde"The low end of the Soul 6 is a tad lightweight. I wish it had a little more low end so I popped in the T/5x, played with those controls a bit. 5 minutes and I was in. It transformed the sound of the Soul 6. It made it sound like a bigger speaker."
- The Audiophiliac"It's a nice addition to a system that doesn't have full range speakers. When I turn it off now, I miss it immediately."
