I had Sound By Design come out and do several things for me. They installed an over the air TV antenna, hung a Bose Surround Sound system for me, and mounted my widescreen TV on the wall. They showed up on time, and were very friendly people. And, they did a very good job on everything. Due to circumstances beyond their control, they could not complete the job on the scheduled Friday, so they came back on Saturday and finished it for me. I thought that was very nice of them!
