What are some quick speaker positioning guidelines that work across the board? Like center channel height, surround height, front main position, front mains against the wall, out from the wall (how far), pointing to a sweet spot, etc. Any suggestions would be greatly appreciated!!! My setup right now consists of my main towers being in the corners of the room (15' apart from each other), all pointing to a "sweet spot" on the loveseat that sits about 15' straight out from the screen. My surrounds are dipole surrounds (fire sound forward and rearward), they are about 7' up from the floor and 7' behind my sweet spot. All speakers are in indentical positions left and right. My center is on top of my tv, pointed down directly at my sweet spot via a director. My front three speakers are laser-aligned (using a laser pointer) to ensure accuracy (as to where they are pointing). So what do you think? Please let me know!
