Two 2x12 (8ohm) + 4ohm Tap: Tone??

[Junk Yard Dog]

I just acquired a Mesa 2x12 and was thinking to run it with my Friedman 2x12, hence I'd need to run the amp at 4ohms (BE50).

I scoured the net a bit yesterday and did not find a lot of info on the differences in tone from 16/8/4ohm tap and what it does to the amp and volume, etc.

Anyone run this setup and if so, what do you hear?

Thanks!

I am curently doing this with a Bogner OS212 and a Friedman 212 for my JJ. The difference between running one cab vs. both has more to do with adding a 2nd cab that has different speakers/dimensions etc. than running at 4 ohms I think. In the end, it sounds awesome and thats all I really need to know...

My experiences with running say a 16 Ohm cab with an 8 ohm out, then switching it to a 4 ohm out has been an increase in low end and more compression with each step down. Less output as well, obviously. But as far as running say a 16 ohm Marshall cab, with the 16 ohm out...then the same type of cab say wired to 4 ohms, and using the 4 ohm out, I haven't tried that.
Not sure if that helps....

Yup, this was the scenario was I was describing. I also have the Bogner OS.

What amp are you doing this with? Do you notice if there's a decrease in volume/or you have to turn up the Master's louder?

Cheers!

I used to run two 8s at 4ohms. Sound was smooth and dark, but not in a negative manner.

I'm still trying to work out the differences.

I doing this with my JJ100, I also just picked up a BE100 in a trade and am running it at 4 ohms with another Bogner OS212 and a 112CPS.

With the JJ, I did not change a thing as a result of adding the additional cab. The sound is a bit more in your face, but I have one cab on top of the other, so by default it has to be more in my face... I'll experiment more and provide an update. Generally speaking I would say I didn't notice any changes in tone or volume outside of the inherent changes brought about by adding an additional but differently specd cab and speaker combination. It sounded great before, it sounds just as good now there is just a bit more to it because Im driving more speakers.

Generally speaking as long as the ohm load of the cabinet is the same as the output it will sound the same. Doesn't really matter if it is 4-4 8-8, or 16-16. There are small differences due to resistance in the windings, the wind ratios not being exact, and series vs parallel wiring of the speakers. The main thing is the power bandwidth of the amp is operating where the amp designer designed it to.

A mismatch one direction will sound darker, and a mismatch the other will sound brighter.
