Stereo loudspeaker system with tweeters mounted on rotatable enlongated arms

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;
• and
• a 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, and
• wherein 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.
