Hi, This is my first post though I've been lurking around for the past year. Just want to say that this a great forum. I'm starting to put my home theater together and would like to ask a question on speaker placement. I'm planning on using towers for the front, and would prefer to use in wall for the rears for aesthetic reasons. I would think my usage would be about 65% music and 35% movies. I have to place the in wall speakers about 7 feet off the floor. The ceilings are about 8 feet. The distance between the speakers will be about 12 feet. The couch will be right in the middle so the height between the ears and speakers will be around 4.5 feet. 1. Is this the correct height for proper sound, especially DVD-A or SACD? The Dolby 5.1 faq recommends about 2 feet, which would be difficult. 2. Do the speakers have to be pointed downward? I've seen some in walls with rotatable tweeters. Would this be the way to go with the setup. Thanks in advance. I'm sure all of you will see more questions for the next few weeks.
