Can anyone recommend a brand or model of in wall speakers that perform great with A/V as well as musically? I have looked at Sonance, Atlantic Technology, and Speakercraft, but not sure if others are just more of the same. I am setting up in a 15 X 15 room, and want the best combo I can get. Should I only focus on THX versions, or is this over marketing? Thanks for anyone's comments that have a good combo of advice.
