Hey,
I wanted to make some clips with my CBB while my folks are gone, but I really want to play it with some other speakers (the Jensens in it are too bright, and I want to try my CBB with my peavey blue marvels in my classic 50, which I actually quite like). Anyways, the CBB has an 8 ohm output, but is it safe if I plug my 4 10" 16 ohm blue marvels into it?
I've always been confused about ohms (i'm bad with technical stuff).

Thanks!

Ohms is a term used to measure resistance....i really dont see a problem here.

edit..maybe aloss of output? because your resitricting the voltage more.?

I'm new to the whole ohms thing as well, but I believe that's a bad idea. If you're just plugging it into one cab (or one output if you're not using a cab, or whatever), you'll need to match the ohms. So you'll need 8 ohm speakers, or if you can change the ohms on the CBB then it'll need to be on 16 ohms.

However, if you somehow manage to get two different cabs of those 16 ohm speakers, then you'll be able to use them just fine with your 8 ohm CBB. It's confusing. Btw, I only learned this stuff yesterday while trying to figure out if a Carvin Legacy head would be compatible with my cab.

haha its probably to do with the resistance laws in paralell and series. its not confusing just a little hard to explain without a demo.

If your amp is outputting at 8 ohms, that means it has to "see" 8 ohms of resistance from the speakers.

EDIT: I did the math wrong, lol... if your cab has ALL its speakers connected in parallel, your cab will have an overall impedance of 4 ohms (cause four 16 ohms in parallel is 4 ohms). So no, you couldn't do it.

BUT! It depends how your cab is wired. Just doing a brief run-through in my head, I don't believe you will be able to hook up those four 16 ohms to your amp in any configuration. Sorry!


Edit 2: I'm not sure how you are doing the speakers (pulling out, replacing; cabs, combo, etc). BUT... if you took TWO of your 10" 16 ohms... you could connect those in parallel, and have 8 ohms.
