[QUOTE="Ivan Beaver, post: 137853, member: 30"] Re: dB calculations It gets A LOT more complicated than that. A larger speaker will narrow its response at a lower freq than a small speaker. So the "overall energy" changes with freq over area. If all you are concerned with is the on axis response, and if the sensitivity is the same for both drivers, then the same power in will result in the same SPL (assuming no reflections etc that would affect the total SPL) I am not aware of any cases in which doubling the power alone will result in more than a 3dB gain. Power is watts. What other units are you talking about? [/QUOTE]
