A:Answer It will handle your Klipsch subwoofer just fine. The subwoofer is self powered, the receiver will only be sending audio signals not power. The Denon S950 does have two subwoofer outs labeled 1 &2. Pretty much every receiver nowadays comes with 2 subwoofer outs hence it being a 7.2. The first number represents 7 speakers (ie front left, right, center speakers, and 4 surrounds. The .2 means 2 subwoofers). If by some odd chance you actually only have one subwoofer output on your receiver, you can daisy chain the second subwoofer off of the first one or buy a 2 in 1 rca splitter cable that plugs into the receiver and plug the subs into the two output jacks.
