Hey,
I just bought 2 12" RF Punch HX2's from my friend along with the box he had them in. I'm looking to get a new box (specifically one built to specs). Looking it up the specs say "sealed box volume 0.8-4.0 cubic feet". That's a pretty large range. What volume should I get in order to get the best performance out of them (more SQ than SPL if there is a choice)? I realize that this may be unpredictable, but is there any general rule to go by?
Thanks,
Dennis

1-1.25 cubic feet(each) is a good volume for a 12, this is with no programs or calculations. Also I don't think that it says 4 cubic feet for a sealed, maybe a ported.

i used to have two RF he 12's, each in a 1.1 cft (2.2 total) enclosure. it sounded decent, but the power of the sub was the limiting factor.

Thanks for the advice guys, I'll start looking for a box around 1 cubic foot volume. Anybody know good places to buy boxes online? The only one I know about is speakerhole.com.
