I am currently looking to purchase a new house. It looks like the preference for a dedicated HT is the basement. When looking for houses with basements what should I look for, and possibly more importantly what should I avoid? I know the obvious headaches to avoid include making sure the basement does not leak, and finding one that does not have multiple metal load baring poles throughout. But what are some of the things that I am missing, that would make my home theater a lot of hassle to create? What size should I look for? Does it have to be without windows? ETC. Any help is appreciated. Thanks.
