REL T/9x Red 10" Subwoofer

Every T/x model boasts sleek, radiused designs and impeccable craftsmanship. But with the T/9x Red, we’ve gone a step further. The seven coats of Italian Racing Red Lacquer took over a year to develop and perfect. It’s the subtle details that elevate this model—the badge atop takes three days to perfect, and each 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 attention to detail that makes REL stand out.

A REL’s essence lies in its driver, and we dedicate immense care and expertise into its design and refinement. The T/9x Red’s driver is no exception. We’ve upgraded its critical centre 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 and more dynamic.

The T/9x Red’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—and most in daily use—we take immense pride in their performance and dependability.

The streamlined 8ms input filters ensure a seamless user experience. With straightforward rotary 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.
