If you buy all brand speakers alike, will that help with the matching? I thought the Klipsch would fit in great as front channel speakers but perhaps not. This is verbatim the Polk instructions on the subwoofer... "Connect the left and right channel speaker output from your electronics to the left and right speaker level INPUT of the subwoofer. Connect the subwoofer left and right speaker level OUTPUT to the corresponding left and righ speakers. If it's easier, you can connect two sets of speaker wires from your electronics running one set to the sub and the other to the front speakers."
