Hi, if I have a 60 watt head, and in my 4 by 12, I have 2 - 25 watt speakers, and 2 - 60 watt speakers, how will the sound be distibuted. Will it be and even split of 15 watts per speaker, or will that change depending on the speaker. Thanks in advance.

From what I remember in the last course I took dealing with electronics, the amount of current going to each speaker will depend more on the resistance of the speaker and how the speakers are wired together than the capacity of the speakers themselves.

I'm no genius, or electronics specialist, but for the sake of attempting to make myself look like a moron(I really do try), I'm gonna try to answer this.
Wouldn't the speakers with more resistance get less of the power?

Trying to think of witty things to put in my sig. Message if you have ideas.
as to my knowledge of speakers, the wattage just refers to max output power. What you need to find out is each individual speaker's resistance, and the way the speakers are wired, then we'd able to let you know exactly the way the sound is being split.

On that note, if the speakers are wired in series, then nothing is split and the current is the same through all...
yes, it depends upon the resistance, but it is extremely rare that cabinet makers use mismatched impedance speakers(like they are all generally 4 ohm, or 8 ohm or 16 ohm depending on wiring). this means that 'wattage' is distributed among them evenly. this is reflected in the formula you use to find a cabinet's wattage rating:

(wattage rating of lowest wattage) x (number of speakers in cabinet) = total wattage handling of cabinet

your cabinet is rated for 100 watts, each speaker will be getting '15 watts' of power(this is not totally true, but we'll keep this short and the math simple) from your 60 watt amp.

so your greenbacks will be getting the same amount of wattage as your v30's, this means they will disproportionately breakup because of their difference in power handling.

Assuming the power (watts) from the amp is distributed evenly between the speakers, variations in speaker sensitivity could affect the volume distribution. It shouldn't be that noticeable if you are using only 1 type of speaker.

good point, i never even mentioned speaker efficiency at all. that falls more in the realm of 'perceived volume' instead of wattage(or conversion from a electrical to audio signal) but is probably actually more pertinent if volume from the speaker(and not wattage to the speaker) is what is being talked about. these attributes all play into how 'loud' a speaker is.
