Description

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.

The additional photos are fantastic.

It's great to read your descriptions and see photos of your creative process. It's a unique blend of physical art, technology and music.

I was a fine art major in college, painted did pencil line drawings, advertising illustration and some charcoal.

After graduation I worked for LTV Aerospace, the only job I could find in art. Our department illustrated fuel (and other) critical systems for fighter jets.

This was when illustrations and text were done by hand and had to look nice. There were only a few of us that could pull that off.

Later commercial photography became my art. The challenge was when film and lighting on location were difficult. Days after returning home the film came off the line and had to be perfect as well as creative if you expected to be hired again.

I understand the difficult turning creative energy into reality. I'm very excited you shared your creation. It made my day and brought a smile to my face.

13mm transducer is adhered to the center of each steel disc, thereby creating 24 separate 12"-diameter flat "drivers"
Understood now.

I don't know of another system like this. Is it something you came up with?

I have never seen anything like that.

Do I understand there are twenty four 13MM transducers (less than .5" cone area each) that reproduce the music ?
