What impedance is this setup?

[Rotus623]

I have one cabinet that has 4 - 16 ohm speakers, wired into series-parallel. If I add a second single speaker cabinet, how does this impedance change? There are 2 photos of possible ways to hook up. One would put the cabinets in parallel and one in series.

The big question is this, since the 4 - 16 ohm cabinet comes down to 16 ohms total, would this act as one 16 ohm driver or would it act strangely if I added another cabinet??

total impedance of parallel connection is 8 ohms, of series connection 32 ohms, either way power would be shared evenly by the quad box and the single speaker; whether it's worthwhile would depend on their relative efficiencies.

Cool, thanks Pete McKay, that is what I thought.
