My answer would be no; but did you ask the A/V guy about that?
I'm in the process of finishing my basement, which includes an area for a home theater.
As a result, I had an A/V guy come out and give me a proposal, which included an Optoma RD50 HDTV, and a sound system composed of a receiver and 6 different speakers (e.g. 2 bookshelf, 2 ceiling, 1 center channel, & 1 subwoofer)!
Not only are the speakers expensive, but they're kind of big as well. Do I really need all of that? Especially if I plan on using the theater to watch mostly news and sports? Thanks.
