Hello,
I like to build two dipole W shaped subs and need to know
how high I can XO them. The drivers will be two 8" or two 10"
per side.
The shape will be like in the attached german thread.

I'm need to cross somewhere between 100Hz and 200Hz as high
as possible.
Any Idea?
Cheers,
TKsys

I'm sure there are a multitude of people on this forum that can answer your questions better than me. However as none of them seem to be stepping up...here are my slightly less informed opinions:
First off it would be impossible to tell you what your upper crossover limit would be with out knowing the specific driver you have in mind. Having said that I would be worried about trying to get too high of a frequency out of a W-frame dipole woofer. I would think you could have trouble with reflections in the higher frequency ranges. However if you wanted to switch to a H-frame woofer I beleive your upper crossover frequency would depend wholly upon the frequency extension that the choosen woofer is capable of.
Hope that helps

TKsys,
If your W-frame fits two 10"-woofers, it will exhibit a (quite heavy) cavity resonance somewhere at 300-350 Hz. You will have to equalize that resonance or cut off around 150 Hz/24 dB to get clear of that resonance.
A H-frame of fitting size will have a resonance at 200-250 Hz (but much less prominent). Since standing waves in my listening room are more pronounced in that region than the dipole resonance I lieve it uncorrected and Xover at 250 Hz.
So if you can integrate a H-frame in your design it would be much more forgiving.
