I'm only about an hour drive from New Bedford, and yeah I was at that show in Hyannis, though my box being tuned to 28hz wasn't really amazing on the meter ....
I think I'm getting a direction here, but I have a couple more questions.
First of all, if I mount amps above the window line does that count as box being below the window line?
Second, how is power measured if I were to try to get into a 2KW category? Do people use "cheater" amps for this? Is there even a "cheater" amp that is rated for something low and puts out far over 2KW?
