Impedance Calculation

I have a sub/sat system where the manufacturer has published an 8 Ohm impedance for the sub and 15 Ohms for the satellites. It's a passive system where the sub crosses over to the sats internally. Is there a way to calculate the system impedance?

I'm using a 20 watt triode amp with 4 and 8 Ohm taps and am not sure which to use - assuming the 8 Ohm at this point but a post in the high efficiency forum made me wonder. A crossover design thread there suggested a forumla that made me wonder if I should be using the 4 Ohm tap.

Any ideas? TIA
