REL T/7x Subwoofer

Ships in 4 to 7 Days
From $2,099

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.

REL T/7x - The Practically Perfect REL

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.

Key Features:

• An evolution of the popular T/7
• Closed box, dual-driver subwoofer delivers a room-filling sound
• 8" Active Driver & 10" Passive Radiator
• 200W RMS of power from the Class A/B amplifier
• In-room frequency response down to -6dB at 30Hz
• High-level, Low-level, & LFE inputs
• Finished with 5 coats of high-gloss black or white lacquer
• Compatible with the Arrow wireless transmitter system (sold separately)

Filtered for Purity

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.


Drive On - Innovative Alloy/Fibre Bass Engines

The 8” long-throw active and 10” passive drivers are where the T/7x derives its incredible speed and clean finish. A thorough revision of critical suspension components is responsible for the agility and suppleness of T/7x. That the T/7x sounds louder and more powerful is to be expected, but few would predict it also is faster, more reactive and transparent than REL's 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

REL has retained their 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.


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. They work 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.

Zero Compression Wireless - Optional Wireless Transmitter

REL has developed a sterling reputation for building the finest sounding, fastest wireless systems available in the industry. This leading brand never rely upon digital compression as it results in thin, lifeless sound. Instead, they have perfected an optional wireless transmitter 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.

Serie T/x - Beyond Convention

REL Acoustics prefer to refine, to build generationally upon a solid foundation while searching relentlessly for every possible way to legitimately improve upon their past performance. Their goals were not simply to improve upon its illustrious predecessor, but to deliver as much as possible of the latest Serie S on a budget.

Serie T/x is instantly seen as crisper, fresher, and a full upgrade. Faster, more transparent sounding system performance awaits you with higher output levels and even greater impact.

REL Acoustics - Do One Thing. Do It Perfectly.

We make subwoofers. That’s it. Nothing else. No distractions. Nothing to steal our focus. No kidding ourselves that we can be good at everything. No trying to conquer the whole world. We just do our best to conquer our bit of it.

We obsess over the details, never satisfied, never finished, constantly refining, simplifying, building iteratively upon what has come before. This is the path to perfection, a never-ending pursuit for better.

From the beginning, this has been a labour of love, born from a desire for a more perfect sound experience. It began with one man’s dissatisfaction with the performance of subwoofers available at the time. That search for better, that pursuit of perfect sound remains the driving force behind REL. It has persisted through changes in ownership, it has driven massive advancements in technology and innovations in designs. Turning loose the power, the drama and the fun that lies within great music and movies.

We take this approach on every model, no matter its size or price. Because we believe the pursuit of perfect sound is a worthy endeavor, one that can start anywhere and last a lifetime. We hope you’ll join us.
