2 cubes good for 12" FI Q?

My Q sounded great in it //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

and its 2.2 cubes after dispacement

 
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 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

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 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 
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.
