Well the room is about a 20x15. I'm temporarily using 2 Alesis Monitor One studio monitors (bookshelf size,
http://www.alesis.com/product.php?id=28) as the front speakers and I've noticed how much more powerful they sound than the 422s. If I do go with 422s all around, then I know I'm going to notice the difference and regret it. That's why I wanted to get the 532s. Maybe I'll try the S-8 and then just trade up if it doesn't fill the sound right? I've been using Lord of the Rings: Return of the King as my benchmark test, what an amazing movie to showcase surround sound!
