First I used perforated steel panels which had great slam and imaging but beamed like crazy. Then came the segmented welding rod panels which gave a much wider sweet spot and sounded wonderful but were just butt ugly to look at. And now I have these lovely new oak lattice copper wire panels which sound as sexy as they look.
These new panels are likewise segmented for wide dispersion. An explanation of segmentation and how it works can be found HERE.
The stator conductors are (90) single-strand 20awg copper wires with .010 XLPVC insulation and 43% open spacing. The wires are physically divided into (15) groups of 6 wires which are electrically powered as (8) discrete groups; consisting of the center 6-wire group and (7) left/right paired 6-wire groups on either side.
The wires are supported by a lattice structure made of interlocking pieces of red oak.
The wires were first stretched to plastic deformation in a special jig to make them perfectly straight. And then the supporting lattice was glued together over the wires, in the jig.
