摘要
A single enclosure multi-channel loudspeaker product 100 uses a novel signal processing system and method to achieve a surprisingly effective psycho-acoustically expanded image breadth by inter-aural crosstalk cancellation, in a manner which relies on a new method for cancellation of apparent sources of inter-aural crosstalk. In the commonly owned Polk® SDA™ (prior art) method, the optimal distance between stereo pair main and effect (SDA) loudspeakers was required to be substantially equal to the ear-to-ear width of a typical user's head. Compact SDA speaker system 100 employs digital signal processing generating selected time delays to acoustically simulate the optimal placement of an effects transducer relative to its main transducer for a physically compact configuration having each side's “main” transducer (e.g., 108LMS) spaced at less than 5.5 inches from the side's corresponding SDA (or effects) transducer (e.g., 108LSS), and this permits the system enclosure to be surprisingly compact, (e.g., width of as little as 341.2 mm).
