Thanks a bunch Peter, for continuing to delve into my box and for trying to model it.
I've simply got to stop and put some real effort into learning HornResp I think...
It does sound very nice, either singly or arrayed...better than I hoped really. Tonality and transients are excellent.
Doesn't image as quiet as well as your boxes up close, given the greater vertical distancing, but still quite nice.
While i was working out the dual mb351's, I also tried mb405's.
They are waay too heavy to put two into a box, as you said sometime back I think, when talking about your DIY driver choices.
The single box I made below, to go with the modular concept, weighs 40 lbs, only 9 less than the dual 351's ! It's a shame it's so heavy, it really is a great sounding driver.
Thanks for that link...it's awesome so many innovative designs are showing up...wow, a back-loaded transmission-line cardioid-midbass !
