Stereo/Mono volume difference?

[YJM_Rocks]

Is there a big difference in volume between 2x60 watts going into a stero 412 or 120 watts mono going in?

120 will be louder. Think of 2 people speaking together at the same volume vs. one person screaming. Now 120 is not double the volume but is louder.

Seems like they should be about the same volume. 30 watts per speaker either way.

Yep, either way you're putting out 120W.

120 watts is louder than 2 60 watters. I may have misread the question

This issue confuses me. In my mind, I see both methods giving a speaker 30 watts, but it seems like 120 mono would be louder.

To rephrase the question, I'll give 2 situations.

Situation A: I have a single 412 cabinet. It is set up in stereo with 2 speakers per channel. Each set of 2 speakers gets 60 watts.

Situation B: I have a single 412 cabinet. It is set up in mono configuration with 4 speakers getting 120 watts.

Which is louder? A or B?

I'd say that assuming you're properly matching the amp's output impedance (16 ohm, 8 ohm, 4 ohm) to the speaker impedance, that they'd be the same. Four speakers pushing 30 watts each, either way.

The cab is set up for 1x16 and 2x8 ohms. I'd be matching it right. (different heads)

The amp is putting out the same either way, it doesn't really matter but that's not really the point of using stereo anyway.
