[. . . ] Ratio ® High-Efficiency Speakers Full-fidelity audio from low-powered multiroom audio systems Ratio ® High-Efficiency Speakers Engineered for maximum performance from low wattage sources, the Ratio High-Efficiency speakers are the first speakers designed specifically for amplified volume controls. [. . . ] The RC61S shares features with the RC61, but uses a pair of 1/2" tweeters and is designed for single-point stereo applications. The RC81 is also for in-ceiling installations, and offers true fidelity in a compact, 8" form factor. For in-wall installation, the RW691 offers a 6" x 9" configuration for efficient performance, while using less space than a traditional speaker design. Designed and built to withstand the rigors of outdoor environments, the RM691 features a corrosion-resistant aluminum grille and ABS enclosure to assure durability in any kind of weather. RC81 8" In-ceiling RW691 6" x 9" In-wall RM691 6" x 9" Indoor/Outdoor Loudspeaker Faster Installation The high-efficiency design carries on beyond their operation. In addition to high-efficiency output, the Ratio line of speakers also features spring-clip locking retainers for faster, easier installation. For in-ceiling speakers, once the mounting hole is cut, the speaker is simply pressed into place and locked into position by the spring-clips. For in­wall speakers, installation is similar, although dogleg clamps are used for final speaker positioning and adjustment.
