REL Acoustics T/9x SE 300 Watt Subwoofer (Green with Envy)
Elevated Design Meets Deep, Controlled Bass
The REL T/9x SE is a premium subwoofer built for listeners who want more than just bass. As the flagship model in REL’s acclaimed T/x Series, the T/9x SE combines powerful low-frequency performance with refined engineering and standout design. Whether you're building a high-end stereo setup or upgrading your home cinema, this subwoofer delivers fast, deep and controlled bass that adds real weight and realism to your sound.
Powered by a high-current 300-watt Class A/B amplifier, the T/9x SE is designed to bring out the detail in every bass note, from subtle acoustic textures to explosive cinematic effects.
Re-engineered Driver for Faster, More Precise Performance
At the heart of the T/9x SE is an upgraded 10-inch FibreCarbon active driver, designed for improved speed and rigidity. The addition of a carbon fibre centre cap reduces weight while increasing structural strength, helping the cone respond more quickly and accurately.
The result is tighter bass, sharper attack and improved dynamic range, making music feel more natural and movies more immersive.
Passive Radiator for Deeper Low Frequencies
Working alongside the front-firing active driver is a 10-inch down-firing passive radiator, extending the subwoofer’s low-frequency reach without adding unwanted distortion. Together, both drivers move air with the authority of a much larger subwoofer, creating deep, room-filling bass with impressive control.
This dual-driver design allows the T/9x SE to produce powerful low-end energy while maintaining REL’s signature musicality.
300W Class A/B Amplification for Superior Control
Unlike many modern subwoofers that rely on digital amplification, REL continues to use a Class A/B amplifier for its natural sound character and precise driver control. The 300W amplifier in the T/9x SE delivers fast transients, excellent grip and smooth power delivery, ensuring bass remains accurate and well-defined even at higher volumes.
This means bass notes start and stop exactly when they should, preserving detail and timing.
Perfect for Music and Home Cinema
One of the standout features of the T/9x SE is its ability to perform equally well in stereo hi-fi and AV systems. Dedicated high-level and LFE inputs allow separate connection and level calibration for music and movies.
This means you can enjoy subtle, integrated bass for music listening while still having the power and impact needed for blockbuster films—without constantly adjusting settings.
Special Edition Finish with Bold Colour Options
The T/9x SE isn’t just designed to sound exceptional—it’s made to stand out visually too. Available in exclusive high-gloss finishes including French Racing Blue, Green With Envy™, Italian Racing Red, Tangerine Dream and Le Mon™ Yellow, this special edition model adds personality to any room.
Premium detailing, including chrome-plated billet aluminium feet and carefully crafted finishing touches, reflect the same attention to detail found in its acoustic design.
Optional Wireless Connectivity
For cleaner installation and greater flexibility, the T/9x SE is compatible with the optional REL Arrow wireless system. This allows you to place the subwoofer where it performs best without being restricted by cable runs, while maintaining high-quality signal transmission.

The REL T/9x SE offers the perfect balance of power, speed and style. With upgraded driver technology, a powerful analogue amplifier and flexible connectivity, it’s an ideal subwoofer for serious music lovers and home cinema enthusiasts alike.
