T/7x is the perfect answer for the real world. It’s compact enough (and beautiful enough) to end arguments before they begin; while powerful enough to easily answer most needs and balanced enough to blend beautifully with many of the quality speakers out there and still flexible enough to work in specialty applications.
Filtered for Purity
The Practically Perfect REL
REL’s legendary High Level Input connection and fast filters are a significant chapter in the REL story. Connecting via the speaker outputs of your amplifier without drawing any power from it may seem like magic, but the real magic lies in the way the sound takes on a natural character and blends seamlessly with your speakers. Unique tuning and special limiters means the T/7x sounds fresher, faster and more dynamic than before.
T/7x is, without reservation, one of the most-balanced RELs of all time. In order to achieve perfect balance, a sub must weigh speed against heft, while ensuring true extension-depth-and do so in a physically harmonious package. T/7x manages to make it all seem easy. Quick and delicate for a perfect blend, it can pound out exceptionally deep, tuneful bass that belies its size and plays louder than most will ever require.
Designed to be Better
Many don’t realize the intense connection between performance and design here at REL. Performance is everything to us and it leads to physical design solutions. Thus it is, that our engineers, in recognizing the need for greater cabinet volume to achieve the goals of greater fluidity and power, turn to the designer. He 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 clean with no unnecessary adornment.
INNOVATIVE ALLOY/FIBRE BASS ENGINES
The 8” long throw active and 10” passive drivers are where T/7x derives its incredible speed and clean finish. A thorough revision of critical suspension components are responsible for the agility and suppleness of T/7x. The T/7x sounds louder and more powerful is expected, but few would predict it also is faster, more reactive and transparent than our prior generation, itself a paragon of virtue. Stiffer suspensions better suited to advanced duty mean not only can each driver trace minute details, but also travel farther and handle more power.
Tried and True Amplifiers
The Power Behind REL
We have retained our signature Class A/B amplifiers used in every generation of Serie T since 2006. Reliability is the key to happy ownership and with some 200,000 and counting of this range leading long happy lives, Serie T/x owners can feel certain of REL’s standard setting reliability. The powerful 200-watt mosfet amplifier used in the T/7x remains an icon of sound and reliability with huge reserves of current. Massive power supplies are used and small upgrades are found everywhere. New driver mosfets that open up performance and transparency and new methods for securing the toroidal transformers mean better performance and superior reliability. The best gets better.
Standby Mode switch is only included on 220V units.
Zero Compression 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.

“This thing can really move some air. It’s dynamic, it’s fast, impactful and actually puts out a lot more sound, and I should say very accurate sound.” Read More +
“These subwoofers are for a more general audience, getting great performance right out of the box. Easy to setup. You plug them in and boom. You get great performance at a relatively low cost.” Read More +
“Their ability for bass output, dynamics, tone of the bass, these types of things. I don’t think we’ve seen things at these prices that have this type of ability out of such a small package and a very attractive package” – Hifi Buys Read More +
“I think it’s designed 75% more for Hifi 2 channel music use, but still has the ability to perform in home cinema. The speed of the T/7x is its outstanding feature. In fact, I don’t think I’ve ever heard a subwoofer like it for a similar price.” – HST Studio Read More +
“The REL T/7x clearly demonstrates how the subwoofer game has moved on in the last 20 years, comfortably outperforming my Strata III. It’s a lot cleaner, a touch more dynamic while offering similar levels of bass extension to it’s ancestor. No small feat for a subwoofer almost half it’s size.” Read More +
A British Audiophile Highly Recommended
The Absolute Sound Editors’ Choice Award 2022
“Few do bass depth and bass speed like this subwoofer at anything like the same price, and for that alone it deserves very high praise because that means the REL sub can keep up with fast musical transients played through equally fast and reactive loudspeakers.” Read More +
T/7x Subwoofer of the Year
“You guys already know about the standout features I love. The polished hardware around the back, around the front, around the radiator, the chassis mounted RCAs, the class A/B amplifier, the super simple setup options and how easy it is to integrate this thing. There are a lot of awesome things I can tell you about the T/7x.” Read More +
What the new REL /x subwoofers bring to your system, in addition to more bass output, is a higher level of definition in the lower frequencies, as well as more presence in the entire frequency spectrum…The best way to really experience what any REL subwoofer can do is to shut it off. The 30 seconds you hear your system with it disabled will convince you. That’s truly all it takes. Read More +
