I have had now for two weeks the Definitive Technology center speaker CLR 2300. Built in 8 inch sub. I highly recommend it or its bigger brother with the 10 inch sub. I had a Paradigm center before and going to the def tech with the built in sub is like night and day. You cant imagine how much low end frequency you gain with the extra bass. Male voices now have the deeper, fuller sound they should have. The sub doesnt give room shaking base but thats not what is intended with the design, thats what your main sub in you system is for. Anyway, highly recommend it, paid $599.
