In Example 1, yes, you get 30W per speaker for a total of 60W delivered to your load. However, this will NOT sound the same as going to 1 8 ohm speaker, because of the way your ears and brain perceive sound. I'm not an expert on that, but you can just plug your amp into 2 different cabs at the store and see what I'm talking about.
In Example 2, I don't feel like doing the math when I'm not getting paid for it! Plus, I would have to know the true impedance of your source (amplifier) and load (speakers), not just the DC resistance. So I don't know what the answer will be. However, power transfer theorems say that it MUST be less total power delivered to your load than if it was a matched load. How much less depends on the math that we don't have all the information to do. Obviously, the more mismatch in impedance the less total power delivered.
I need a bigger brain to keep up with you guys!
