- The zHorn Heruka uses the Fostex FE 168 E Sigma driver, a
6.5 inch driver.
- This is an extremely open and smooth driver, with
substantial bass. Compared to the zHorn Dakini with a 4 inch Fostex
108, this is far superior in the lower midrange into the bass. It is
very efficient at 94.5
db/watt/meter.
- The dimensions are 8.5 x 14 x 36 inches.
- The cabinets can be gotten in various veneered plywoods.
They are
then French polished with a dozen or more coats of hand rubbed shellac
and oil.
- The driver is mounted on a one inch thick piece of
hardwood. The theory is that the vibration moves quickly through
hardwood. The energy moves into the cabinet which is made of Russian
Baltic Birch with a shell of Candian Fir plywoods.
- Internal wiring varies: ideally one would use the same
wiring that is connected from the amplifier.
- Cork lines 30%-40% of the horn path, especially near the
mouth (the terminus). This seems to absorb some of the upper range
frequencies and spurious high frequencies caused for winds inside the
horn path: the result is a quieter background to the sound. Bows to
Yamamura for this technique.

- See this page for construction plans and for a photo of the
speaker just before it is clamped. Here.
- These photos were taken in my front yard. Much of the
construction of the zHorn is along side the Yahara River here in
Madison
, Wisconson.

variations. Made by Ray Boston. Here.

Szabo in Hungry. Here.
