This is sort of a follow up to my last post. I'm trying to convince myself now to go with a CSi5 instead of a CSi3 and I wanted some input on whether or not I need to take into account where it will live. I have a custom built wood entertainment center which holds my TV and my HT equipment. Over the TV are 3 compartments (side by side). The center compartment, which is the largest one, is where the CSix would go. My question is, the compartment is about 25 x 10 x 16. The CSi5 will come close to filling it. Will this affect the sound quality and would having the smaller CSi3 with more air flow around the speaker make any difference?
