One more thing. Western Electric 10 gauge bulk speaker cable is very nice on your speaker and has a wonderful warm, full bodied tone. It is very inexpensive as an 8 foot set would cost about $65.
I am using it and love it. Great tone and as far from bright as I can imagine.

Cut the 16ft run in half for an 8 foot set. The seller has longer lengths available and is a great ebay seller. I am confident it will bring your system up another level from the current cable you are using.
