[. . . ] Boston Horizon Boston Horizon HS Floorstanding Speakers HS Floorstanding Speakers (Left) HS 450 in mist with Silver grille (Right) HS 460 in Midnight with Onyx grille play strong. [. . . ] Boston Acoustics engineers every component of every system to meet the highest performance standards (our own). So we're careful to build all our products with strict attention to everything from the choice of materials to the details of fit and finish. It's how we've been exceeding the expectations of serious listeners for nearly thirty years. May we have your full attention? HS Series floorstanding speakers pack a lot of technology into their trim ABS exteriors. MBOS (Maximum Bass Output System) uses passive radiators and a rear port to improve bass performance -- without the audible noise of a port alone. Proprietary Deep Channel® Design (DCD) poly cones with phase plugs deliver smooth, consistent response at any output level. And the cabinets themselves are heavily braced to reduce unwanted resonances.
