For installation applications where a center channel is intentionally removed from a surround system to allow for design requirements or otherwise cannot be used, the SI-663 is the perfect high performance solution. A pair of these in-wall speakers can eliminate the need for a dedicated center channel when wired for dual channel operation. For situations where a third SI-663 can be used as a dedicated center channel, the trio can be wired in standard configuration, allowing each to discretely provide left, center or right channels for a seamless front sound stage.

Each of the RBH Sound speaker series can be mixed and combined within the like series, creating a vast selection of options to create a unique home theater experience.
