That calculator is worthless, unless one is talking about listening outdoors or in an anechoic chamber. For more, better to point you here than to repeat myself.

Bottom line is really that Q900's demand very little from an amp, and chances are excellent that one's subwoofers are the limiting factor when using main speakers of that size and efficiency.

Do you have a better method / calculation to determine the relationship amp power, number of speakers, seating distance to MLP and speaker placement?
