Terms and Conditions

The reference version of the SI-663, the SI-663/R is designed for demanding custom installations where a center channel cannot be used or is intentionally removed for design considerations. When wired for dual channel operation, a pair of the SI-663/R reference in-wall speakers can provide a discrete and dedicated center channel from the left and right speakers. When three SI-663/Rs can be used, the trio wired in single-channel configuration can provide a seamless, reference-level front sound stage from their covert in-wall locations.
