Small Room: 604's, 14's, or 19's?

As long as the cab is properly braced and damped ? I wouldn't worry about that too much..

I have guests this weekend that were unexpected by me (my wife neglected to mention them) I'll get the full specs early this week.

So VERY appreciated!!!

OK, so it wasn't early in the week.
I have the updated results for the 604E on a Woofer tester II. Note that I used 330mm as the piston diameter.

I have the updated results for the 604E on a Woofer tester II. Note that I used 315mm as the piston diameter.

Mahalo, much appreciated!

No problem. Check the updated numbers though. I used a piston diameter that was a bit off on the first run. It doesn't change much but if your using a box calculator, you might as well use correct numbers.
