It was a total disaster working with Sound By Design. I had spent $1,000 purchasing a subwoofer and wanted professional help installing it. Sound by Design assured me that they would set it up and integrate it with my TV in a professional manner. But when the technician arrived, he was unable to do the job. He couldn't get the subwoofer to work and said the receiver was defective. He also didn't set up any of the other peripherals I needed for the TV. I still had to pay them $250 for an installation that didn't happen. I was extremely disappointed. It was a waste of time and money. I ended up installing everything myself. I was also charged a $150 restocking fee for the subwoofer return. Working with Sound By Design was aggravating.
