Rel Acoustics

Rel Acoustics - T/9i - Subwoofer

T/9i represents the most of T/i that we can deliver, and if sheer output alone is a primary requirement for your theater or music system then read no further. The combination of a lightweight, composite 10” driver coupled to a matching 10” T/i passive delivers speed, slam and attack when called upon but also is capable of tracing more delicate passages when necessary. Large in sonic scale, the T/9i is ideal for mating up with floor standing speakers and rooms that are on the medium-to-large size. Powerful, concussive, yet beautiful.
