I want to mix different speakers in my cabinet. Will a 150-watt speaker overpower a 50-watt speaker?
You want to compare each speaker’s SPL rating (measured @ 1W/1m). This tells how loud the speakers will be. Eminence recommends that they be within 2 dB of one another. This will insure that one of the speakers is not significantly louder than the other. The power rating is really only good for determining the maximum continuous power that can be applied.
