noob question on wiring front towers....

[swingle007]

I'm sure this is very basic, I've just never had to deal with it before as I've always had a different type of speaker (cheap). Just got this set of paradigm towers and they have two sets of spots to screw down your speaker wire to. One set is for high frequency and the other for low. I can only assume that both should be hooked up in order to give you the best of both. For now I have my wires running to the low as the high was basically all tweeter. If I am supposed to run wire to all 4 how would I do so with just one spot to run wire from for L and R on the back of the receiver? either I'm missing some splitter type device i can get from monoprice, or I'm not supposed to run both at the same time....also, it has that little gold toned clip that connects to both the top and bottom positive input.....come explain this to a noob...

thanks,
John
