The Helix is a single-unit stereo speaker, designed to reproduce primarily ethereal/electronic background music. Overall dimensions: 30" wide x 90" tall. (I had already created a similar design as a 14-ft high outdoor wind-motion sculpture, also pictured.)

The Hiwave 13mm 16-ohm voice coil transducer pictured is one of 24 individual units attached to the center of each 12" diameter disc. A piezoelectric horn tweeter installed at the top is "waveguide" outfitted for 360" dispersion. The output of a single 60wpc stereo amplifier utilizing a 10-band EQ is connected to an impedance matcher which easily drives the entire assembly. A Dayton 8" powered sub augments the lowest bass.

The sound is pleasantly house-filling (located in an open loft setting) at low/mid volume levels, and frequency response is rather well balanced for what actually started out as a conceptual art piece.
