i built a box drawn up by moe lester and for some reason my port ended up being about 3" instead of 2.5".. could someone calculate what my box is tuned to for me please... thanks alot


these are the box plans i went by but eneded up with 3" port instead of a 2.5"

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..

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.
