Nothing goes as quick as I'd like even on long weekends like this.
Some progress has been made in some driver testing/evaluations with regards to planned Modula series builds.
I did get the Millenium Excel tweeter mated with an H-65 waveguide- results weren't bad, but they weren't everything I'd hoped for, compared with the results using the Scanspeak D2608/9130.
First, here's a series of curves taken at 5 degree intervals from 0 degrees to 45 degrees
A little confusing, but one which is clear is that there's something going on with the behavior at about 12 kHz causing a dip and deviation from pattern control.
Trying to make a little more sense out of this, I plotted some different regions- first, the curves in the 0 to 30 degree range:
I also plotted three curves in the 25 to 40 range:
Note quite my predetermined idea of perfection, but look at what the Accuton C13N looked like in a H-65 waveguide:
Makes the Millenium Excel results look rather splendid in comparison, huh?
Well, I think I'm going to go ahead for now and try working with the Excel, beef up a couple of waveguides, and get a new test panel ready.
