Newbie, need help about series speaker


Hi,
I'm new in audio, and need help about series speaker. How if I series 2 piece of two way speaker, ex. 2 Pi Theatre? I think the impedance will double, and there no different in sensitivity, but it will raise the power handling, am I correct? Is there any other effect? Someone tell me that the series config is different from pararel config due to Passive X-over network, he explain to me that the signal is goes through the passive of the first speaker system before entering the second. What is the result or effect if I do that? Any reply will be appreciated.
