So, let me get this straight, if you take like a twin reverb amp, which is set up for 4 ohms, if you were to replace the speakers.. you would get, two, 2 ohm each, wired for series? thanks! Ricstar

Well yes you can connect 2 x 2 ohm speakers in series to give an overall impedance that the amp sees as 4 ohms which is what you need to maintain .........or

Connect 2 x 8 ohm speakers in parallel to give 4 ohms total load on the amp.
This is because resistances in parallel are calculated as 1 over 1/R1 + 1/R2

eg The reciprocal of 0.125 + 0.125 = 0.25 easier to write than type on here. ie 1 divided by 0.25

Hope you can follow that.

Another way of doing the same calculation and easier to type is

8 x 8
______ = 4 ohms

8 + 8

so use 2 x 8 ohm speakers in parallel as stated in my previous reply.
