T/9x SE

Embracing the vibrant allure of French Racing Blue, Green With Envy™, Italian Racing Red, Tangerine Dream, and Le Mon™ Yellow, the T/9x SE subwoofers stand out not merely as audio equipment but as a testament to the fusion of aesthetic elegance and acoustic mastery. As part of REL's illustrious lineage, these models represent a distinctive blend of sound engineering and design flair. Every detail, from meticulous craftsmanship to advanced performance features, resonates with luxury and sophistication. Whether you're an audiophile, a design aficionado, or someone who appreciates the sublime, the T/9x SE subwoofers deliver an auditory experience as profound and captivating as their visual appeal. Secure your T/9x Special Edition subwoofers today and immerse yourself in a sonic masterpiece.

Masterfully Crafted to Mesmerize

Every T/x model boasts sleek, radiused designs and impeccable craftsmanship. But with the T/9x Special Edition, we’ve taken it a step further. It's the subtle details that elevates these models—the badge atop takes three days to perfect, and each solid billet aluminium foot undergoes a three-day chroming process. We meticulously layer copper, nickel, and chrome, allowing each coat a day to set before adding the next. This is the kind of attention to detail that makes REL stand out.

The Heartbeat of Every REL

A REL's essence lies in its driver, and we dedicate immense care and expertise to its design and refinement. The T/9x’s driver is no exception. We've upgraded its critical center cap with carbon fibre, enhancing its stiffness for better bass articulation. By reducing its weight by 10 grams, we've achieved a faster response, and a notable 1.2 dB increase in output, making the T/9x faster, more dynamic, and just a skosh louder.

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.

Amplified Emotion

T/9x's amplifier embodies power and precision with its 300-watt Class A/B monoblock design. Using reliable mosfet designs with integrated heat sinks, these amplifiers have been the driving force behind the Serie T flagships since 2007. With nearly 90,000 units in circulation—most in daily use—we take immense pride in their performance and dependability.

The streamlined 8ms input filters ensure a seamless blend between the subwoofer and speaker. With straightforward rotary analog controls for gain, crossover, and LFE Gain, and an intuitive 0–180-degree phase switch, setting up your REL is straightforward and hassle-free. No misplaced remote controls or complicated apps—just timeless, dependable engineering.

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.

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.
