Yes, the Crown calculator isn't the best for a home setting, I just went with it because I knew they had one on their web page.


Here is a better amp power calculator that actually speaks to the room reinforcement before you get down to the calculator as well as a DB level exposure table at the bottom

I can remember seeing a calculator that actually added the room reinforcement into the equation, checked 2 pages worth of searches still haven't seen it......
