Just out of curiosity, what volume will you calculate for a sealed enclosure with the following parameters?Vas = 0.702 ft^3
fs = 44 Hz
Qts = .279
Qtc=.707
I calculated a volume of 0.13 ft^3
I used the online web site: http://www.lalena.com/audio/calculator/box/
Does your program come close? I am just about to start construction a quasi-array with 8 Focal 5-1/4" per side, and a single point source tweeter
Just checking….
