REL T/5x Active Subwoofer Review: Small Footprint, Monumental Bass
Welcome to our REL T/5x Active Subwoofer Review, where we dive deep into why this compact powerhouse from REL is poised to reshape your listening experience. The REL T/5x Active Subwoofer Review will unveil its secret floor-firing mechanism, hand-polished high-gloss finishes, and precision engineering that belie its modest dimensions.

Elegant Form Meets Acoustic Function
The T/5x is an elegant reinvention of the bestselling T/5, featuring a grill-less cabinet finished in five coats of hand-polished lacquer, available in High Gloss White or Piano Black. REL’s ingenious cabinet design appears deceptively compact—measuring just 300 x 307 x 313 mm—yet houses an increased acoustic volume for deeper, cleaner bass. Its softly rounded enclosure minimises diffraction, allowing the subwoofer to blend seamlessly with any interior décor while retaining a discreet presence.

Driven by Precision: 8" Long-Throw Bass Engine
At the heart of the T/5x lies an 8-inch FibreAlloy™ long-throw driver, complete with an inverted alloy dust cap and a robust steel chassis. This driver extends to -6 dB at 32 Hz, delivering a bass performance that far exceeds expectations for its size. Whether you’re rediscovering vinyl classics or immersing yourself in the explosions of a home theatre soundtrack, the T/5x captures every nuance with authority and refinement.
Seamless Integration and Connectivity
Connectivity is effortless. High Level inputs use a Neutrik Speakon connector, ensuring perfect integration with existing speaker cables. Low Level (RCA) and Theatre .1/LFE inputs adapt easily to two-channel hi-fi rigs or custom home theatre setups. For those who demand wireless flexibility, REL’s Arrow™ Wireless system (optional) provides zero-compression transmission, enabling fast, dynamic bass without the clutter of extra cables.
Reliability and Protection
REL’s legendary dependability remains intact thanks to a 125 W RMS Class A/B amplifier and upgraded internal components that enhance transparency and speed. A comprehensive protection suite—Fully Electronic Set Safe, D.C. Fault detection, and Output Short protection—safeguards both the subwoofer and your entire system, ensuring years of rock-solid performance.
Who Should Consider the REL T/5x?
This subwoofer is ideal for audiophiles and home theatre enthusiasts in small to medium-sized rooms who refuse to compromise on bass quality or aesthetics. If you crave deep, room-filling low end without sacrificing floor space or décor, the T/5x is tailored for you. It’s also perfect for vinyl purists seeking that extra tactile dimension, film buffs chasing cinematic impact, and gamers who demand lightning-fast transient response.
Pros and Cons
- Pros: Exceptional bass extension to 32 Hz; refined, grill-less design; compact footprint; robust 125 W Class A/B amplifier; seamless speaker-to-subwoofer transition; optional zero-compression wireless; comprehensive protection suite.
- Cons: Wireless module sold separately; premium finishes may require careful placement to avoid scratches.
