Abstract
A loudspeaker apparatus includes an elongated hollow tube having two open ends, which tube may be a rigid or telescoping tube, and has a wide range speaker mounted at each end of the hollow tube. A pair of deflector surfaces may be flat, polymer surfaces mounted to a base and are positioned at an angle facing each speaker at each end of the tube for deflecting the sound waves emanating from each speaker in accordance with the positioning of the tube. The tube may also have a tuned port formed into the side of the tube and connected to an arcuate passageway built into the hollow portion of the inside of the tube for producing a bass resonance from the backwaves of both speakers.
