I have the oppurtunity to pickup a used ported box built to 2 cubes tuned @ 32hz.

Would a 12" Q sound okay in this box? It seems like most people are running them in 2.5 cubes.

Thanks!

My box is 3.5 cubic feet tuned to 33hz. There is a ridiculously steep drop-off at about 50hz, I think my box positioning is a pretty big factor in that though, but still if I rebuild I think I'll make mine slightly smaller.

You also have a 15"...

oh yeah forgot about that part, good call :)

I wasn't trying to say that his should be bigger, I was just stating that I built mine close to the upper end of Fi's recommended enclosure size, and that I experienced the steep drop-off at 50hz I described.

has alot to do with tuning and the cars natural resonant frequency :)

Yeah that and I wanted to test my box turned around. I read a bunch of stuff about it firing into the cabin and having bad results so I thought I'd try it lol.

When it was facing the back I didn't notice anything, but facing into the cabin it seems like a certain frequency range is louder than before but there is a pretty severe drop in others.
