Well and i am building a cab with 2 12s and one 15 inch speaker from Eminence. and i was wondering how to wired and speakers up. The head is 8 or 16 ohm selectible.

What would be the better ohm to run and how would i wire the speakers up to that ohm?

The 12s are 8ohm. The 15 is 8 ohms

thanks in advance

Mike

Well if all the speakers are 8 ohms run the head at 8 ohms

If you are using 3 8 ohm speakers you aren't going to be able to wire them up for 8 ohms (Well maybe if you add extra electronics to the cab).

If one of them, say the 15 inch, was 16 ohms you would be fine (wire the 2 8's in series then wire that in parallel with the 16 ohm for 8 ohms).
Go here for various speaker wiring diagrams:

Ohms wired in series double the ohm rating, wired in parallel, halve the ohm rating.

When working with multiple speakers of the same ohmage, then yes. Not with different ohmages.

As in my example. Guess I should have specified that.

"If you are using 3 8 ohm speakers you aren't going to be able to wire them up for 8 ohms (Well maybe if you add extra electronics to the cab)."

And check the link on speaker wiring.

That's because three speaker wiring is tough to pull off well. It usually doesn't sound as good as pairs or sets of four.

well i pplay in b standard in the little band i am in thought the 15 would give more low end, so how much will it differ with 2 12s instead?

I'm not sure how much of a difference it would make. But bi-amping might be a better idea than trying to wire them all to one amp. But I'm way too lazy to haul around a 15" even if there is a good way to wire it.
