Quick Polk Monitor 40 Question

[Ladic]

So I'm ready to hook up these speakers but on the back, there are 2 set of inputs apparently? which one I use to hook up to the reciever? the top or bottom one?

here is a picture of the back

The 2 sets of posts are for Bi-wiring, one for the tweeter and the other is for the woofer. You don't have to do this so they included a gold shorting plate as seen in the picture. So if you want to bi-wire then you'll have to take the shorting plate off.
