Hello Wayne,

first of all congratulations for the original designs.
May I have the plans for the theater 3 an 4 please? I want to build a 3 way system with lateral woofer, 12" midrange and horn tweeter and I'm interested to test your pi alignment theory.

I have a few more question:

1. how much influence have the proportions of H/W/D for the final result of the bass?
2. If I don't have so much space can I made a front baffle a little bit narrow? If so, how much is the tollerance (10-20%) ?
3. I have noticed that you use speakers with higher Qts that usually (or in theory) are not suitable for the reflex application - especially the eminence. Is this the "secret" to obtain a deep bass and high efficiency from a PA speaker?


Thank You in advance!

A.
