Quasar question (BD-Design)

Hi-
The Quasars look very good. I have some Visaton B200s, some ribbon tweeters and nice Parts Express/ Dayton IB 15s designed for infinite baffle. All drivers are high Qts and high efficiency. My question has to do with baffle thickness: do the multiple layers effect dispersion of the rear wave? I prefer the Quasar design to the Visaton No BB, which I was going to build...
Thanks,
Harry Z

Hi Harry,
...do with baffle thickness: do the multiple layers effect dispersion of the rear wave?
The multiple layers create a sort of tube making the "width" of the baffle a bit wider without negative influence on the bass when you cross around 250-300Hz. The mid-range is more effected which is helping low Q drivers but might disturb high Q drivers. If that is the case then you should apply damping material behind that driver.
Ciao,
Bert

What if I were to make the holes increasingly wider with each layer behind the midrange driver in order to accommodate the back wave?

That would reduce the tube effect but could start a horn effect which might be more disturbing... there is only one way to find out.
