2-way 5-1/4-inch floorstanding loudspeaker. HS 450 speakers pack a lot of technology into their trim 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. Front baffles are gently curved. And the cabinets themselves are heavily braced to reduce unwanted resonances. The combined result is the natural, captivating sound you expect from Boston, with clean, contemporary style. They are available in Mist (off-white) or Midnight (dark gray) with optional color grilles that are sure to complement your décor!
