REL T/7x — Subwoofer

The Perfect Balance of Speed, Depth, and Musicality

The T/7x sits in the ideal position at the heart of REL's Serie T range. More muscle than the T/5x, yet still compact and elegant, it delivers that rare combination: the speed and delicacy for a perfect blend with your speakers, combined with the ability to produce exceptionally deep, musical bass that defies its size. One of the most balanced RELs of all time.

Listening Impressions

Connected at high level via the supplied Neutrik Speakon cable, the T/7x integrates with remarkable naturalness. Its dual architecture — active driver at the front, passive radiator firing down — gives it a transient speed and bass texture that simpler down-firing configurations struggle to match. On music, it reads the note rather than the effect: an upright bass has body, a kick drum has impact without excess. Through the dedicated LFE input for home cinema, the impact is immediate and controlled. Properly dialled in, it disappears spatially — you hear a wider, more stable soundstage, not a "bass point" in the corner.

Key Features

• Active + Passive Architecture: Front-firing 200mm FibreAlloy™ active driver + 254mm down-firing passive radiator. Speed, depth, and natural extension.
• 200W Class A/B MOSFET Amplifier: Generous RMS power with huge current reserves. Unique REL tuning and special limiters — faster and more dynamic than the previous generation.
• 30 Hz Extension (-6dB): Truly deep bass in a compact format — ideal for rooms of 15 to 35 m².
• Dual Music and Cinema Use: Simultaneous Hi Level Neutrik Speakon connection for stereo music + dedicated LFE input with independent volume for home theatre.
• Arrow Wireless Compatible (optional): REL zero-compression wireless system — fast enough to use on one channel of a stereo pair while the other remains hardwired.
