Features

Masterfully Crafted to Mesmerize
Design 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
Driver 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.
Amplified Emotion
Amplifier 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
Wireless 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.
