I believe the statement is that you need 10X the power to go twice as loud. With that in mind, many feel that smaller increases of power don't really give you much. I follow the theory that more juice is more juice.




Hey Bob, that statemant may sound impressive, but the math doesn't really work out.

When I use the calculator for a 100 watt amp I get 113 db at the listening position at 12 feet from the M80s. To get twice as loud, and assuming to most people an increase of 7 db (now this is the subjective part I know) you only have to go to a 500 watt amplifer to get to 120 db. Which to is 5 times the power to double the volume.

Am I missing someting?
