have an 18.5' x 18' room with a hardwood floor and wood beam ceiling. I have a Toshiba 65H80 TV and want to put together a home theater system. I have an old pair of Klipsch speakers that I'm going to retire. I've inherited 4 Klipsch Quintet speakers that I'd like to include in this setup if possible. I need: - sub - center - pair of front mains - receiver Any suggestions are appreciated. I have a budget of $1500-$2000. Thanks in advance.
