hi all,

with the possibilities multiplying
time to focus.

driver 909 crossed over at
24db per octave, 1200Hz

horn 1: 600Hz round tractrix
horn 2: " square 'trix
horn 3: " radial

friend has figured out how to
get solidworks to drive a router
from the algebra - will buy a
sheet of the truck decking -
shoot for density.

still to consider: round to sq
& machining first section of
throat for ease of comparison.

let me know if i'm more or less
on track...

happy trails,

a
