Does anyone rember how to calculate impedance?

Jeffreybehr-I was giving advice to another Audiogoner. He is runnig a satellite system with two mini-monitors and two subs. It looks like there is no crossover for the subs. He essentially is running them in parrallel. He twisted the wires together and connected them to his reciever. I suggested he try running thme in series. I wanted to make sure he did not improperly load his amp. He says the speakers are rated at six ohms and his amp has selectable impedance. Sounds Like he is okay.
I learned this stuff years ago and forgot. It's not really a problem with the level of components I use. Thanks!

El Gordo....you just spilled the beans on your age.

Did the el cassette stay on the market for more than 6 months?

For multiple resistors in parallel:

1 1 1 1
- = - + - + - ...........
Rt R1 R2 R3

therefore four 8 ohm speakers in parallel equal 2 ohms.

I love answering electrical questions BUT remember, sound has NOTHING to do with spec's!!!!!!!!!!!!! Just listen.

Imin2u. Afraid I have to disagree with you. The ultimate test is in the listening, spec's do matter. I want a product that is technicaly correct. I have no patience with "flat earthers". If the designer is departing from the laws of physics I want to know why.
This would make it good thread of it's own.

Sorry for the igorance but what's the differnece of having the speakers hooked up in series or in parallel ?

Tks.
