*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.
