Wow! wouldn't you know it my Definitive Technology CLR3000 center speaker finally came in when i was out of town on business.
I have to say that matched front and center speakers really do make a difference.
I installed the CLR3000 along with my 7002 towers and recalibrated and the timbre and sound is awesome!.
Center, normally provides most of the vocal sound on TV and Movies. The CLR3000 has a built-in 150 watt power 1o inch subwoofer, so the center can be set as large. That along with a 1" dome tweeter and two 6 1/2 Inch upper-bass/mid range drivers gives a very wide range and realistic center channel sound.
In my case it perfectly fits on the top shelve on my Amoire cabinet above the TV and visually is astehtica and unnoticable ... that is except for the sound
My experiential advce:
(1) Put your money in the front and center speakers
(2) Match the timbre
(3) Buy one level higher than you think you can afford
