Congratulations, you got very luck on the speakers. B&W makes nice stuff. Welcome to the ranks of people who enjoy better sound.

If there is a metal jumper between the upper and lower pair you can just connect one pair. If not you'll have to connect both pairs or make a number out of small pieces of speaker wire.

Yep, what Mr. Lowry said.

Hey nashville.
Welcome to the forums. Great first post.

My uncle and I lucked into a pair of B&W DM602s not not too long ago. Very nice speakers.

And our intern Ariel Bitran very recently had the same question regarding binding posts. You can read about his story here, if you're interested. The answers given above are right on.
