[QUOTE="shredder2, post: 8815287, member: 674047"] Model them up... I did. I'd shoot for a 44-48hz tuning /w/ enough port area to make use of the output those X's have. 4ths should never be tuned under 40hz unless you want a wind tunnel and even then it'll sound like a5s imo... Be sure to allow for output when porting but don't fixate on that. Musicality and output can be balanced. The worst thing you can do is go big ratio /w/ a narrow bandwidth. Maybe grab a design somewhere, build it/understand it and improve it eventually if you feel you can. That design you put up is yuck... no hate... but unless you want a spl bandpass hitting in the 60's it'll fall flat when playing lows. Tune 45 or so for best results is my opinion. [/QUOTE]
