I put the small box parameters into Boxplot and also WinlSD. I'm not sure what I'm doing in terms of "box tuning". Both programs gave me a port of 4"X165"!!! So I made the port 1.25" and the length came down to 5". Does that sound right? The box is (internal) 21X14X11.5, the plate amp 9X7X4, and the Titanic:
fs 16.26
vas 9.89
qms 8.226
qes .428
qts .407
xmax 14.22 mm
Oh yeah. The P.E. site says the Titanic was designed "for a 3.5 cu.ft. sealed enclosure". Whatever, should I give up on the small box and go up to at least 3.5, ported? Or can I get good response down to, say 20Hz and up to an 80Hz cut-off with the 2 cu. ft. I've got?
Thanks for the help.
