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.
