When is enough power enough?
I'm not sure, except that if you use the common headroom formulas you will blow yourself and your guests right out of the room. Is 600 wpc all around with a 2KW sub amp enough in an 11' x 17' x 8' theater enough? I think so. May even be overkill. Tom

Tom, that is ridiculous. Must sound fantastic.

Let's hope your seating is equipped with "seats-belts" to keep you and your guest strapped-in when watching movies.

So I used the online calculator mentioned earlier in the thread. It said that, with my 87 dB/1W/1m speakers, to hit 105 dB SPL at 3 meters I need 1133 watts. That's with 3 dB of headroom.
With no headroom I would need half that, or 568 Watts. So according to that calculator, I'm just squeaking by with 600W in each channel. So if I want 3 dB of headroom, I need to trade in all three MC 601's for MC 1.2KW's. I can tell for sure to take that results of that calculator with a grain of salt. I can easily get to the 105 dB reference levels on a lot less than 600 Watts. SPL calculators make a lot of assumptions and that one must be using 4PI stearadian spherical space, 1/r^2 attenuation, and zero reverberant soundfield. I've never found a situation where reasonably efficient speakers couldn't hit 105 dB SPL with amps in the 200 wpc class in reasonably sized rooms.
