I just wanted to share my recent experience of changing the wiring for my surrounds. Two weeks ago I purchased some JBL N24II's and was pretty happy with them except I noticed they tended to be a little "boomy". Even before the purchase, I had been planning to replace the wiring to my surrounds. I've had the Home Depot 12-gauge SKU:#551893(fat)clear wire sitting in a closet for a couple of months. I've been putting it off because it involves climbing up into the attic. My surround runs are 50 foot each and I've read on this forum that 16-gauge wire can cause roll-off with lengths that long. Well I replaced both runs yesterday, and let me tell you working with this cable is a major pain in the ass! With the jacket on this cable it's the equivalent of working with 10 or 8-gauge wire. Anyway, I immediately noticed a difference with the low end on the surrounds. It's much more natural and the "boominess" is gone completely! To be honest the difference in the high end is not as dramatic. But, I probably don't have the educated ear that a lot of guys on this forum have. I never would have thought that replacing the wiring could make THAT much of a difference! It's was $34 dollars well spent! Because of this forum I am NOW very pleased with my new surrounds! Thanks!
