My room is L shaped with main stereo/tv section about 21' x 24' with a 12' x 11' adjoining area that holds a bar area.
I have approximately 10 feet behind couch so lots of room for surrounds and sides.
I am in Canada / Saskatchewan so everything is more expensive here. RB51 pair is normally $500 so $300 plus tax is a deal that happens 1 or 2 times a year. RS42 pair is normally $639 so $300 plus tax is a really good deal and very rare to find. Purchases at London Drugs which is an awesome chain in Canada but have little selection. The 62i centre would be a special order and therefore would be at full price. My SW12 sub was bought on sale for $400 (regular price is $750).
I appreciate all the comments and advice so far. Great forum.
