See the previous post. Looks like 16ohms all wired in parallel for a 4ohm load.

nominal 4ohm, and could easily be lower
is that controversal to fullrange setup
well, I take it 'fullrange' designs usually works best with small simpler amps, or even tube flea amps

on the topic Hilding Horn
might have phase issues between port/mouth and drivers
I have tried a similar design not long ago, with single 12"
since it actually is a lower midrange horn I found that it works best the usual front horn way, with driver in closed back chamber
not to be negative, but I dont think its that 'straight forward'

Wasn´t it hard to fit the 12" to such a tiny baffle cutout?

On a slightly more serious note, there might be lots of issues regarding phase,
a front loaded horn would be 100cm deep, harder to accomodate in several domestic environments.

As i see it all design principles suffers from a multitude of drawbacks, i try my ideas, dont write that much about the failures as that would fill all forums there are, but write about what i like, might still suffer from an unlimited amount of deficiensies, but i like the way they play music.
