I have the Piega c-10ltd 11 feet from the back wall and am getting the deepest bass and best soundstage. Where your speakers may look the best most likely they won't sound the best. You don't listen with your eyes. Its fun when you get the biggest upgrade you will ever find without spending a dime
The Power of Positioning
I moved my Sonus Faber EA 11's out from the rear wall in my listening room. They were closer to two feet from the rear and I brought them out an additional foot to three feet from the rear wall. Well let me tell you the improvement was fantastic. The upgrade in sound was greater than any equipment upgrade I have ever made. I am now a believer in proper setup. Work on your room and positioning and you will be rewarded.
