REL T9 active subwoofer

REL'S T/9i is the flagship model within the company's Ti series and boasts a level of sound quality and build integrity worthy of wearing the crown. Featuring a lightweight yet highly rigid composite driver, 10" in size working in tandem with a matching 10" passive driver, the Ti/9 is capable of pushing vast amounts of air at an outstanding speed without compromise. 

The T/i9 is designed to add an entirely new level of depth to your favourite audio sources, whether that be as part of a dynamic and immersive home theatre system, or as the warmth in a high quality two channel stereo hifi application. Performs best in medium/larger environments and when put together with a pair of good quality floorstanding loudspeakers.
