I wasn't before Joerg showed up either. There are quite a few knowledgeable people here.
Yet still Joerg the issue of which circuit, series or parallel, absolutely produces the highest spl from the speakers per a specific input voltage has not been answered.
Dave can you take it from here?
If your amp can handle lower resistance applications (high current) then a parallel wiring configuration should be the louder of the two options because it will lower the resistance and increase the output of the amp.
Here is one way too look at it.
When you go from 1 to 2 speakers, you theoretically get a 3dB increase in output with the same power input. But since an amp doesn't normally give the same output into different impedances, the overall output would change. So, if you were to wire in parallel, you would theoretically double the power (+3 db) and by wiring in series, you would cut the power in half (-3db). The final result of going from `1 to 2 speakers is a 6dB increase in power from the parallel option and a 0 dB increase with the series option.
