8cft with 10in round port

[Cdieselfan 10+ year member]

Building a enclosure for a guy I work with. Its 8cft and I have a 10in flare port I made awile back. Its for a couple TC9 15s, each will be getting around 1200 watts from a Kole Q1-3000d (have a couple more in my sale thread //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif) According to PSPs site it needs to be around 15" long to tune it to 53hz. Does this sound about right? Will be taking pics as it built after design gets the ok.

I have 2 RF 15" T1s in a 7-8cft box in my living room. I was shooting for 28-32hz tuning with the 10" port. My port length is 30" - 31" . Its fed with a Behringer EP2500 1200watts per sub. It gets low and loud. I think trying to tune it that high is way off. The guy I bought the enclosure off of had it tuned down to 10hz for his home theater setup. I cut the box down and even filled it with some hard closed cell foam to tune it a little higher so it would be better suited for music.
