Subwoofer enthusiasts SVS also make normal loudspeakers. This is a new one, cost $199 per speaker (although by the time it travels across the Atlantic it will probably be £199 per speaker) at Frank Harvey or TheMovieRooms in Edinburgh. It is, apparerently, suitable for high speakers in Dolby Atmos, DTS:X and Auro 3D configurations.
