I am getting set to complete the installation of my parents' HTIB. The first attempt succeeded in running the wires, although hiding them along the walls was a major effort. They didn't want to tuck very well along the edge of the carpet but I did the best I could. The carpet is in a condo and can't be lifted. The speaker mounts I used for the Mains were BT-33's and wouldn't allow the speakers to be aimed directly forward. They just didn't extend out far enough. So I am buying a pair of BT-34's and will mount them head-high(when seated) on the side of the TV cabinet. It is not a very component-friendly cabinet but all attemps to convince buying a new one have failed. So the side mounts will have to do. The Surrounds are on stands also head-high although I can raise them to approx. 45 inches. Questions... 1. Should I mount the Mains head-high even though the Centre speaker will be about 12 inches higher on top of the TV or should I mount them at the same level as the Centre? 2. Should I raise the Surrounds to their maximum height for better imaging? Thanks. The first test with Red October really impressed my parents. They have never even had stereo so this was a real eye (ear) opener to them. Glad I could do this for their 80th Birthdays.
