Radio Shack has the RCA speakers on sale for 58.00 ea. These are the same speakers that got rave reviews in audio magazines a couple of years ago when they were badged under the Optimus brand name. I'm curious about how they compare to the JBL N and S series. These are the speakers. http://www.radioshack.com/product.as...5Fid=40%2D5037 All opinions welcomed.
