hopefully I'll be there.

I'm not being sarcastic, I really do wanna see more pics of your install. I know you guys know your stuff, wish we could see you at some Toronto shows.

I know you didnt copy anything, that's a very common box design.

I have an idea for you to try

make a box that is very shallow (not very tall) and put subs up side down (invert mounted) with the port outside and firing up.

something similar to this,

I tried this in 2008 at Ottawa 2x show without succes. Its very difficult to drop the frequency to 57 Hz with a 8'' port without be illegal in height.

I also tried this box at the 2x show in Montreal in 2008:

And I don't count the ton of slotted port box tried in 2009...

how much trunk space do you have?

Is that a earthquake D2?? have not seen 1 of those for a long time I use to have 2 of them.

Its an Earthquake PHD3 and Yuli I have 40'' x 26'' on floor, 40'' x 20'' on top and 20'' of height to stay legal.

Matheiw what note do you play? I will draw something for you with subs and port up to try to be legal and loud.

58hz...
