Is this a good 15" BTL Loaded enclosure?

[dopey 0]

39" wide

18" deep

22" tall

1.5" walls

4.5 box volume

76sq" of port

32" long port

tuned to 34hz

With available space, I'm tuned a little high (it's a big interior, peaks around 40hz)...and I'm lacking port area.

Should I go longer on the port to get lower or should I go longer and wider and keep the tuning freq (or possibly let it raise)?

Why are you doing 1.5 walls.

If anything, just do a double baffle.

Also, I think you forgot to include the port wall as part of displacement... just and :fyi: no biggie.

I LOVED mine in 4.5 @33hz with 90 sq. in. of port.

NOOOOOOOOOOOOoooooooooooooooooooooooooooo............

j/k

If you want double walls good. If this is for daily I'd tune a little lower. I have mine tuned around 35hz and I wish I was tuned just a little lower (32hz-ish), although it still sounds great. If this is for daily I can't see why you'll have a problem with it.

as far as port area fi recommends 12-16sq per cubic foot. 16x4.5= 72sq, so you would seem to be good. Just bevel the ends of the port, and again, I'd tune a little lower. Good luck
