Meticulously Crafted to Captivate

Every T/x model features sleek, rounded designs and exceptional craftsmanship. With the T/9x Special Edition, we’ve taken this dedication to detail further. It’s the finer elements that elevate these models—each badge is perfected over three days, and every solid billet aluminum foot undergoes a three-day chroming process. We carefully layer copper, nickel, and chrome, allowing each finish a full day to set before applying the next. This meticulous attention to detail sets REL apart.

The Core of Every REL

The essence of a REL subwoofer lies in its driver, and we commit extensive care to its development and refinement. The T/9x’s driver shines with an upgraded carbon fibre center cap that bolsters stiffness for enhanced bass articulation. By trimming 10 grams from its weight, we’ve achieved a quicker response and a significant 1.2 dB increase in output, making the T/9x faster, more dynamic, and slightly louder. 

Elevated Emotion

The T/9x’s amplifier combines power with precision in a 300-watt Class A/B monoblock design. Leveraging reliable MOSFET technology with integrated heat sinks, these amplifiers have powered the Serie T flagships since 2007. With nearly 90,000 units in circulation—most of which are in daily use—we take pride in their performance and reliability.

Streamlined 8ms input filters ensure a smooth integration between the subwoofer and speakers. Setup is straightforward with easy-to-use rotary analog controls for gain, crossover, and LFE Gain, along with an intuitive 0–180-degree phase switch—no misplaced remotes or complicated apps required; just timeless, reliable engineering.

The T/9x Special Edition: A Harmony of Speed, Sound, and Colour

With vibrant shades of Italian Racing Red, Le Mon™ Yellow, and Tangerine Dream, alongside exceptional craftsmanship and enhanced performance, the T/9x SE transcends typical subwoofers. They serve as statement pieces within our T/x lineup. Whether you’re a discerning audiophile or seeking the ultimate in performance for your investment, the T/9x SE promises an unparalleled ownership experience.
