I am about to upgrade the six speakers in my 5.1 setup and was hoping to get some advice. I have the following three considerations. 1. As my home theater is about to become a nursery, I have to move my theater set-up from a small (~10'x12') dedicated room into my much larger, oddly shaped den. The den is about half of a ~18'x24' room that consists of my den, dining room, foyer with two half walls separating rooms. Long story short, I have a visually pleasing room that I am sure has terrible acoustics but is my only choice for home theater. 2. When I dragged my wife out to view some speaker options, a sales guy introduced her to the concept of towers w/ built-in subwoofers (she was looking at - not listening to, mind you - the Def Tech 2000TL series). The sales guy told her that with these speakers, the "hideous black box in the corner wouldn't be necessary." She instantly found a favorite, and I realized that I should have left her at home. 3. My current B&W CC6/DM602/LM1 setup has served me very well for years, but I am looking to upgrade (budget about $2,500). I have a dog and a kid is in the future, so I want the stability of floorstanding speakers - rather than bookshelves on stands. Also, wall-mounted rears are mandatory. I was listening to a Def Tech set-up that includes a CLR2300 center, 2002TL fronts, and BP2x rears and was very impressed. Granted, it was only my first audition. The system is within my budget, but I am somewhat skeptical of speakers with built-in subwoofers (even the center had a built-in sub). My system is primarily used for movies, and I like low frequency activity as much as the next guy (but rocking the house is not a requirement). How much LF performance would I be giving up by going with a system such as this? Given my situation, what other particular speakers/systems should I consider in my auditions? A free-standing sub is an option, but a happy wife would be preferred. Can any Def Tech 200xTL owners offer insight?
