The Gold Line Series 6.5" In-Ceiling Stereo Speaker is designed to be used in spaces where a pair won't fit or isn't needed. This speaker offers high end performance and serves as an upgrade to the Blue Line Single Stereo Speaker. Left and right channels are both wired to this speaker eliminating the need to install two separate stereo speakers. Optimized for whole house music distribution, it is moisture resistant for areas such as the bathroom or porch. It features a dual voice coil glass fiber woofer, two 1" aluminum dome tweeters, high grade crossover, 1/2 inch IR target knockout and high end gold push pin speaker connectors. Installation is also made easy by the use of self centering screw heads and compatibility with the On-Q Pre-Construction Speaker Brackets.
