Subwoofers — Rel Acoustics T/9x

The T/9x is a powered subwoofer from REL Acoustics, a British manufacturer with a considerable reputation for serious subwoofer engineering, built as part of the brand's well-regarded T-series. The T/9x brings REL's considered engineering to accessible dedicated bass reinforcement.

Key specs that matter

Rated response reaches down to 27Hz. Internal amplification delivers 300W. At 37.0 x 34.0 x 39.3cm, the T/9x maintains a manageable footprint consistent with REL's broader T-series positioning as an accessible entry point into the brand's catalogue.

Sound and use context

Expect controlled, musically integrated bass reinforcement reflecting REL's considerable reputation for careful attention to blending bass with a main speaker system's own character, rather than simply adding raw output.

Pairing

As a self-powered subwoofer, the T/9x connects to a preamplifier, integrated amplifier or AV receiver's subwoofer output directly, working alongside a broader main-speaker system.

Alternatives

REL Acoustics' broader Carbon and Planar series offer alternatives at different scales and price tiers for buyers wanting either more accessible or more ambitious REL engineering.
