The REL T/9x SE sits at the top of REL Acoustics’ T/x line, a powered subwoofer the British brand positions around “elevated design, enhanced performance and pure sonic refinement.” REL built the T/9x SE for greater clarity, richer dynamics and a striking visual presence intended to elevate any system it joins.
What drives the REL T/9x SE
At the heart of the REL T/9x SE is a 10-inch FibreCarbon driver, delivering what REL describes as faster, more detailed bass performance, paired with a 10-inch down-firing passive radiator of matching size for extended low-frequency depth. Power comes from a 300-watt Class A/B amplifier, chosen to deliver natural, expressive bass rather than chasing raw output figures alone.
Connectivity follows REL’s familiar approach for the T/x series, with both high-level and low-level inputs so the T/9x SE can integrate directly with a main amplifier’s speaker outputs as well as line-level sources, a hallmark of REL’s design philosophy for blending a subwoofer invisibly into a stereo or home-theater system.

Built for stereo and home cinema alike
REL positions the REL T/9x SE as equally suited to premium stereo setups and home-theater systems, with the option to run a single unit or a matched stereo pair for more even bass distribution across a room. The SE finish adds a more striking visual presence to the standard T/9x, available across REL’s range of bold colourways rather than a single standard finish.

Pricing and availability
The REL T/9x SE is priced at $1,799 per unit and is available now through REL’s dealer network and directly via REL’s own website, where it is also offered as a matched stereo pair.
