RBH SI-615 In‑Ceiling Speaker

6½ 2-Way In-ceiling Speaker

Product Description

When only the absolute finest performance will do, look to the Signature Series SI-615 in-ceiling speaker. Featuring a 6-1/2” aluminum cone woofer and a 1-inch pivoting ring-radiator tweeter, the SI-615 delivers award-winning performance that is on par with other Signature Series models. The SI-615 is primarily designed to be used as in-ceiling channels for object-based surround systems, but is also equally adept when used in a pair for high-end stereo listening or other whole-house audio applications.
