ABSTRACT:
A loudspeaker system and a loudspeaker housing system uses a plurality of smaller rated loudspeakers to generate a high-level output. Specifically, the plurality of loudspeakers are housed in a corresponding number of substantially cylindrical sound collecting tubes, one tube for each loudspeaker. Sound waves, which are generated toward the rear of each loudspeaker and which are otherwise attenuated by the insulation material or reflected by baffles and/or walls and ultimately dissipate, instead travel through the tube, the tube forming a sound traveling path. Each tube converge and merge smoothly into a single substantially cylindrical tube. The sound waves traveling through the individual tubes are merged at the converged tube. The outlet of the single converged tube is connected to or is integral with a conventional or specialized sound concentrating horn to direct the captured sound to a desired direction.
