T/7x

The T/7x is REL's argument for what a subwoofer should do for music. The Neutrik Speakon high-level input is the headline — instead of taking a line-level signal from the AVR's sub-out, the T/7x connects directly to the amp's speaker terminals via a bespoke cable, and pulls its signal from there. The point isn't convenience; the point is that the sub now hears what the amplifier has done — the tonal character, the timing, the way the amp loads under transients — and stays coherent with the main speakers in a way line-level designs can't match.

Tonally it's tight and tuneful. The sealed 8-inch driver doesn't extend as low as a comparable 12-inch SVS, and it won't deliver the chest-thump impact when an LFE explosion lands. That's the deal you're making. What you get instead is a sub that fills out the bottom octaves of a floorstander or a large bookshelf without ever announcing itself — bass that you notice when it stops, not when it starts.

Compact enough to disappear into a normal living room, the T/7x prioritises integration over imposition. Set the crossover by ear or by REW, dial in phase against the mains, and it does its job invisibly.

This is a music-first sub. For a system that does both film and music, the SVS SB-2000 Pro at similar money is the better all-rounder. For a stereo system where the bass needs to integrate rather than impose, the T/7x is the right call.
