Review: Great service - And great sub
Review: Klein aber oho! - Ich habe zwei bestellt, um meine 2 Wege Lautsprecher zu unterstützen. Wenn die richtige Einstellung und Position erst einmal gefunden ist, machen die „Kleinen“ einen prima Job! ( trockener, knackiger Bass) Ich möchte sie nicht mehr missen!!!

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great service
*by J***T on 17 November 2022*

And great sub

### ⭐⭐⭐⭐⭐ Klein aber oho!

Ich habe zwei bestellt, um meine 2 Wege Lautsprecher zu unterstützen. Wenn die richtige Einstellung und Position erst einmal gefunden ist, machen die „Kleinen“ einen prima Job! ( trockener, knackiger Bass) Ich möchte sie nicht mehr missen!!!

### ⭐⭐⭐⭐⭐ Works well with Focal speakers when bought as a pair
*by S***A on 25 February 2023*

The Rel T Zero work well as a pair. I would probably have gone with a pair of the T5i’s if I had the budget. The Tzeros do work well without over powering the room. I actually tried the first Rel Tzero on my surround sound system on the main level and it worked very well. It added a dimension to the sound that was clearly missing from the Paradigm in ceiling speakers. I then moved the unit downstairs and added a second Rel Tzero. Very happy with the fast performance of the sub. Snappy bass perfect for music. Definitely recommend using a pair with floor standing speakers.
