I have been looking at the warfedale diamond 10.2, canton GLE 426, and Cambridge SX 60 as bookshelf speakers for my fronts in a 2-channel setup for music. I recently bought the Dayton 1000 sub and I really like it. my room is 15x15 area. these are about 300 dollars which is what I want to spend. can I get some opinions on these 3 as my choices. thanks so much!
