can i mix speaker wattage ?

[benindavis]

I have a Peavey XXL100 and I am building a cab for it. I was thinking Id like to put in 2 Celestion G12T-75's and 2 Celestion Vintage 30's. That is 2 speakers at 75W and 2 at 60W. Is that not a good idea or would it be ok? The amp itself is a 100W output max.
Thanks for your input!!

Of course you can. The amp has no idea what speakers or how many of them are in your cab. All it sees it the total impedance of the cab. The amp wil provide the 100 watts, but it has no idea what the wattage rating of your speakers are in the cab. The four speakers will share power equally. In this case that means 25w per speaker, each of them can handle that.

Just as an example though, say you had three 50w speakers and one little 15 watt speaker. if you put those in a 4x12, then the 100 watts would still divide equally, and that means the 15 watter would still get 25w and burn up.

I'm gonna ask you another question -- are all four of your speakers rated at 8 ohms, or all four rated at 16-ohms, or are your speakers a mix of both different impedances AND different power handling ratings?

All the speakers have the same ohms So, I take it Im good to go ahead as long as Im not using a speaker with too low of wattage or different ohms.
