Short answer: the REL Acoustics T/7x is the newer model that replaces the REL Acoustics T-7, but only the REL Acoustics T-7 has been measured and ranked so far, so this comparison is on specs and features rather than sound. The REL Acoustics T-7 is discontinued, so it is now a used buy.
What the REL Acoustics T/7x offers: Sealed subwoofer with a front-firing 8-inch driver and a down-firing 10-inch passive radiator, driven by a 200W Class A/B amplifier.
What the REL Acoustics T-7 brings: Compact 8-inch with 200W RMS stays extremely solid and composed at high volumes.
Price: the REL Acoustics T/7x lists at $1,299 and the REL Acoustics T-7 at $699.
Buy the REL Acoustics T-7 if you want a speaker whose sound quality has been measured and ranked.
Buy the REL Acoustics T/7x if you want the newer model, and you can wait for measurements to confirm how it sounds.

The Two Speakers In Full
REL Acoustics T/7x: $1,299.00 Amazon eBay
Older model: the REL Acoustics T-7 (rated 3.6/5).
Pros: Sealed subwoofer with a front-firing 8-inch driver and a down-firing 10-inch passive radiator, driven by a 200W Class A/B amplifier. REL rates extension to 30Hz at -6dB. A high-level speaker-wire input and an RCA/LFE input can be connected at the same time for music and movies.
Cons: No independent measurements yet, so its output can’t be compared with ranked subwoofers. There is no app, EQ or room correction, and an 8-inch driver limits output in a large room.

Newer model: the REL Acoustics T/7x. It’s likely to perform similarly, though we don’t have measurements to confirm that yet.
Pros: Compact 8-inch with 200W RMS stays extremely solid and composed at high volumes. Fast agile response ideal for music with speed and depth. No overhang or bloat. Excellent Speakon connectivity and build quality.
Cons: Discontinued.
