it all depends man...the sub may have a loose suspension, or isn't mechanically suited for ported...so they use a smaller enclosure to "tighten" the repsonse
i know the CVX or CVR...forget which one also recommends a smaller ported enclosure over sealed...so i dunno man.
I have tried e-mailing the company,no responce. I am useing spec's that came in the owner's manule. I found a on line store that show the spec's flip floped.
I would rather not tell you the brand,there not very liked on this fourm,or any I have found. The sub's suspension is very stiff. The sub's VAS is 44L.
hmmm. i dunno then...but to add to my post up there...even though Stillwater Designs(kicker) rec's a smaller box for the CVX® it still shines in alrger ported enclosures.....just tell us the sub...and we can give you a general box volume to use.
