A speaker system has a first baffle (2) supporting a first speaker unit for producing sounds in a first frequency range (low frequencies), at least one second baffle (27L), (27R) supporting a second speaker unit for producing sounds in a second frequency range which is higher than the first frequency range (middle and/or high frequencies), the second baffles (27L), (27R) being smaller than the first baffles (2). The second baffle (27L), (27R) are spaced a predetermined distance from the first baffle (2). The speaker system has a reduced baffle effect, and increases direct sounds radiated directly from the speaker units, as compared with indirect sounds radiated backwards from a baffle, thereby improving frequency characteristics in the middle frequencies and providing excellent sound image localization.

[ We claim:] [1.] A stereo speaker system comprising:a first baffle supporting a first speaker unit for producing sounds in a first frequency range;a plurality of second baffles each supporting a respective second speaker unit for producing sounds in a second frequency range, said second frequency range being higher than the first frequency range, said second baffles being smaller than said first baffle;said plurality of second baffles being spaced a predetermined distance from said first baffle; anda plurality of non-metallic hollow pipes each angularly movably connected at a first end to said first baffle and at a second opposite end pivotally connected to one of said second baffles so that each of said second baffles is attached to said first baffle for independent relative movement, said pipes having a length so that sounds from said first speaker unit and sounds from each second speaker unit do not interfere and so that sounds from said second speaker units cooperate to produce a stereophonic effect,wherein said plurality of second baffles can be independently moved toward and away from a listener, andwherein said pipes are tapered decreasing gradually in diameter from said first end to said second end and are integrally formed of a material made of epoxy resin mixed with carbon fibers so that the pipes have a resistance of at least 170 .OMEGA./m and propagate sound at a velocity of at least 5000 m/sec with a sharpness of resonance of at most 500 Hz.
