Design and core features
REL built this as a stereo-friendly sealed 10-inch subwoofer. You get a 10-inch active driver, a down-firing passive radiator, and a Class A/B amplifier aimed at control and texture.
What that means in practice is simple: bass lines have shape, not just weight. On a well-set-up system with quality turntable speakers, kick drums and upright bass sound more connected to the music.
How the REL T/9x fits into a vinyl stereo system
Your turntable doesn't connect straight to the sub. The normal path is turntable to phono preamp, then into a stereo amp or receiver, then out to speakers, with the REL joining through High Level Input or low-level input.
High Level Input means the sub takes its signal from your amplifier's speaker outputs rather than directly from the turntable. That's one of the biggest reasons people buy this model.
If you've got a Rega or Pro-Ject deck feeding an older stereo receiver with no dedicated sub out, the speaker-level connection gives you a practical path to better bass without rebuilding the whole chain.
If you need a refresher on the signal chain, start with what a phono preamp does and our turntable setup guide.

The Klipsch SPL-120 sits in a different lane. It's more of a theater-leaning alternative for buyers who want impact first and subtlety second.
Once you understand the connection options, the REL's premium starts to look practical, not flashy.
