Re: Amp Watt Mismatch (2x12)
Since both speakers are rated the same, they both should be getting the same amount of power from the amp, but the way they'll respond to that power will differ. The 120 watt speaker shouldn't breakup at all with the amount of power that it's being fed, but the 25 watt speaker will probably start to breakup pretty quickly. I haven't run that large of mismatch, but a few years ago I found it necessary for a job to run a cabinet that has a 25 watt Fender speaker and a 75 watt Emminence. Running 80 watts into the system produced just what I described. I didn't find it to be a terribly attractive tone, since what was required to get the desired overdrive in the 75 watt was overkill for the 25 watt.

Make sense ... the 25w vs. 120w is an exageration but I see what you mean.
My thinking was ... yes, the 25w will breakup faster but the higher watt speaker will simply be as transparent as can be and reduce the overall grittyness of the Greenback.

Re: Amp Watt Mismatch (2x12)
i smell a blown speaker thread coming soon..
personally i think you should stick within 10 watts of the rating of your amp.. but thats only because im not too much a fan of overdriven speakers

Yep, both will get the same amount of power if the impedances are matched.

Oye! This mess started because I was going to get a THD Univalve or Dr. Z Maz Junior so I loaded up on Greenbacks ... then I spotted a JCM 600 head real cheap and jumped on it.
Ohhh well ... get 2 G12H-30s or some Weber equivalent and be done with it.

Sooner or later you will probably blow the 120 watt speaker not the 25 watt. I've done this twice. The "Speaker Doctor" here in Charlotte explained it to me once but I've forgotten why this is so. All I know is that when I've mismatched speakers it's always the highest rated speaker that blows.
