It's tuned to ~33-34Hz

so a half inch wider port only ended up being about ~1-2hz higher.. ((the box was tuned to 32hz at a 2.5" port))...for some reason i thought it would have made a bigger difference than that... thats not bad then..

anybody want to double check that???

just under 34hz

thats pretty sweet that a half inch wider port only upps the freq by not even 2hz... leaves a little room for slight error like the stupid stuff i pulled while makeing this box... good stuff

No, a narrower port makes the tuning lower.
