Apologies in advance - this is ANOTHER cab/ohmage question

Bear in mind you'll be measuring the DC resistance not the impedance. It's likely to be somewhere around 6 ohms.

Exactamundo, I was hoping the OP could report "I measured it with my meter and got 6.1 ohms" (for example) in which case we could explain that his meter is measuring DC resistance and he's dealing with a 8 ohm nominal impedance speaker....I didn't want to get the water too muddy with the whole DC resistance versus AC impedance discussion, after all we were asked about "ohmage"...
 
You guys are way too clever for me, but I think I have more than enough information now, thank you.

And when I need another lexicological lesson I'll certainly know where to come ... ;-)

I never understood what goes through manufacturers heads by not clearly spelling this stuff out ON the amps.

Just adding the word "total" after "minimum x Ohms" as well as "included driver impedance: x Ohms" won't make their profit margin disappear. It would likely save a few bucks in warranty repairs, or time dealing with customer service calls when people blow up their amps.
 
There is no such word as ohmage the word is impedance! Your spell checker should have told you that! :(

The units of measure of impedance is ohms. z=DCR + capacitive reactance + inductive reactance.

"ohmage" is an acceptable "technical slang" for describing total electrical load. Some techs say--"ohm it out" when checking for shorts or opens.

Not in my book! Why use a slang made up word instead of the correct term? If we take this to the extreme we will no longer be able to communicate with each other properly.
 
This is so very silly. The word is in the Collins English Dictionary.

Get over it boys!

Again, don't assume it's an 8 ohm internal driver. ALL WA Scout combo's come equipped with a 4 ohm driver, the 8 ohm version is a special order. Adding an 8 ohm 15 to a 4 ohm 12 gives you 2.6 ohms total, and more importantly, 2/3 of the power goes to the 12, and the other 1/3 to the 15. Find out for sure what's what before running that rig wide open.

Note that even the physics-illiterate folk at Collins only say it's equivalent to resistance, so it's not relevant to speaker impedance.
 
"SUGGESTED LOAD 4 OHMS" This text stretches beneath both sockets.

I interpret this to mean that the suggested TOTAL LOAD from both sockets should ideally be 4 ohms and that therefore the internal load must be 8 ohms and that therefore an extensions speaker should ideally also be 8 ohms, giving a total load of 4 ohms.

Whoa! NOT, I'm sure. Mesa would want this amp to be as loud as possible with it's single (probably 4 Ohm) 12 inch speaker. There is already info provided suggesting that an 8 Ohm extension cab is available for the combo when it is special-ordered with an 8 Ohm speaker. Yes, the lowest recommended impedance is 4 Ohms, but I bet you have a 4 Ohm speaker in there. If I'm right, you can either put a factory 8-ohm speaker in the combo and use an 8-ohm extension cab or you can use just the amp with a 4-ohm cab with more umph than your single twelve your using now.
