We tend to think of home theater as a suburban thing, logically enough.  Unless you have more space than what city dwellers designate a “one-bedroom,” then it’s unlikely you’ll be able to devote an entire room for that purpose.  When I moved into my current apartment, I realized that I didn’t actually need a so-called “living room,” and thus I decided to use the second room in my apartment – the one that was not my bedroom – as a combination of office and home theater.
