Description

T/9x

Serie T/x

Serie T/x is instantly seen as crisper, fresher, a full upgrade . Our goals were not simply to improve upon its illustrious predecessor, but to deliver as much as possible of our latest Serie S on a budget. Faster, more transparent sounding system performance awaits you with higher output levels and even greater impact.

Serie T/9x: Bigger AND Better

The Series Flagship

The job of any range topper for REL is to deliver more of everything, particularly output and dynamics. The 9x is no different in this regard, as it delivers the goods in both music and theatre applications. 9x, however, delivers a level of intimacy, clarity and speed that means there are no longer trade-offs between the sonic balance of smaller models weighed against the power and scale of a model 9.

The all new 9x has even greater output than before, but the headline news is the way it sacrifices nothing in clarity and transparency to achieve this. At this price it opens the pathway for owners of high performance European floor and stand mounted monitors and smaller panel speakers to enjoy truly full range sound.

Reimagined, Then Reengineered

A completely redesigned flagship

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.

Outsized Performance

Innovative Alloy/Fibre Bass Engines

To achieve higher output with better control requires a complete overhaul of the suspension components. Much like the suspension on a sports car, these items are responsible for the tuning and feel of our designs. By increasing the cabinet volume, efficiency is improved yielding higher output for no more amplifier power. Less back pressure inside the cabinet means we can tune for a stiffer, better controlled driver suspension. We retained the best aspects of our previous design, such as the aluminum center cap responsible for stiffening the lightweight 10” (250mm) cone while adding almost no mass. The updated combination produces considerably better attack and dynamics with greater transparency.

Tried and True Amplifiers

The Brains Behind the Brawn

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 300 watt mosfet amplifier used in the T/9x remains an icon with huge reserves of current, massive power supplies but 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 strength.

REL’s legendary High Level Input connection and fast filters are a significant part of 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. Unique tuning and special limiters means the T/x range sounds fresher, faster and more dynamic than before.

Standby Mode switch is only included on 220V units.

Wireless That Doesn’t Compress the Sound

Unlimited Possibilities

At REL, we’ve developed a sterling reputation for building the finest sounding, fastest wireless systems available in the industry. We never rely upon digital compression as it results in dull, 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 conventionally with cable.

Reviews + Awards

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 +

Tone Audio

“Textures, layers and fast attacking response were some of the best I’ve heard in my home. They can be aggressive for Rock music or nuanced during live performances, and this all applies to home theater as well.” Read More +

When you get it out of the box the superior build quality, attractive design and gorgeous finish provides an immediate feeling of luxury. It's not all looks either, and this discreetly-compact subwoofer does an awful lot with its 10-inch driver, 10-inch passive radiator and 300W of Class A/B power. Read More +

AV Forums Highly Recommended

“I was amazed at the T/9x’s ability to energise the room without sounding woolly or frayed. It also managed to deliver powerful bass while retaining REL’s trademark speed and flair. This is a remarkable achievement in terms of redesigning and reengineering an existing product, and one that’s sure to please existing fans of the brand. It should also make it plenty of new ones.” Read More +

Why Choose REL Acoustics

REL’s T and S Series subwoofers are built on a principle that experienced listeners recognise immediately—bass should complete the system, not call attention to itself. It’s an approach that has earned REL a strong following in carefully assembled hi-fi systems across Australia, where integration and musical balance are prioritised over sheer output.

Signature Design and Sound

With the S Series, stackability allows multiple subwoofers to work together, improving room interaction, increasing headroom, and delivering a more relaxed, immersive sound—particularly in larger or more complex spaces.

Set up thoughtfully, a REL subwoofer doesn’t simply add bass—it reveals depth, texture, and realism already present in the recording.

REL Acoustics Product Range

The T Series introduces this philosophy with speed, agility, and an ease of placement that suits a wide range of systems. The S Series builds on this with greater scale, control, and authority, offering a more expansive and effortless presentation. Central to both ranges is REL’s high level input, allowing the subwoofer to take its signal directly from your amplifier. This preserves the tonal character and timing of your system, resulting in bass that feels cohesive and naturally connected.
