I'm looking to buy a new amp for my keyboards, and I was wondering if there's a formula I can use to help me calculate some of the objective specs I should look for. Something along the lines of: I usually play on square-room venues, of A' x B' dimensions, for C number of people. What wattage does my amp need to be loud enough for the room?

Of course, this doesn't account for the subjective "feel" of the amp, but I'm wondering if such a formula exists.

Think this would be more on topic over at avp.stackexchange – Dr Mayhem Sep 4 '11 at 23:01
I'm not sure it's right here, but it's not right at avp either -- it's about performing, not recording. I'd love an answer on this too. – slim Nov 25 '11 at 12:30

This question made me think of The 12-Volt.

It was the first thing that came to mind, and I personally hope someone could find some opensource-recourse/resource. Is this the right direction,

That's actually awesome, and seems to be just what I was looking for. Thank you! – Gustavo Mori Dec 5 '11 at 2:08
