Center channel Dialect

I have a B&W CMC (not the 06' version but the earlier one), anyway this is part of a complete cm ht setup. I have problems understanding the dialogue in movies a lot of the time. Can someone give me some insight as to why this is happening.

Boy that could be a lot of reasons.

Where is the center? On a stand, cramped into a cabinet, any room behind it?

Have you calibrated your system, can you change the eq settings on the center?

Have just tried playing with the level of the center?

Need to know a LOT more about your setup like what receiver or pre-pro/amp you are using and how it is configured and whether or not it is properly calibrated. As Greg mentioned, how is the speaker positioned? Does this happen on all sources or only DVDs?

Thought I would need to provide more info but wasnt sure where to begin. I have a Yamaha RXV 2200, Yamaha DVD S1700, CM4's Front and Rear, CMC, and Defininitive Tech TL100 Sub. All speakers hooked up via Accoustic Research Pro II 12Gauge and Banana Plugs. CMC located directly beneath tv in an entertainment center with lots of room behind, nothing blocking port. Speaker is not more than 6-12" below and 8' in front of my listening position. Center is +2.5 or 3.0 in setup. I had a Radio Shack digital sound meter for a day and did the test tone thing like the good people at Audioclassics told me to and set up all channels at 75db. My ht room is approx. 16'w x 14'L x 12'H, with hard wood floors. Hope that helps!
Thanks for any suggestions-

Is the speaker in an enclosure? Can you pull it all the way out to the very front of whatever it is sitting in? With it 8ft away and positioned low, you may want to also try to angle it slightly up toward you, and of course you may want to play with the level as I have my center set +1dB higher than standard calibrated level to get it to sound the way I want for movies.

Jeremy,
A critical component of any sound system is the room!!

Based on your comments above, it sounds like you have yet to employ acoustic treatments in your theater. Half of what reaches your ears from a typical seating position in a HT arrives via room reflections. Honeycomb filtering is extremely damaging to sound fidelity, and the above is a classic example of the effects of untreated room acoustics.

As the direct sound waves reach your ears, you're also receiving sound waves milliseconds later via room reflections. The end result of clashing sound waves are peaks & nulls that will either boost or cancel various frequencies. Some frequencies may be canceled by 30-60db or more!!

Another key result of the above is muddied dialog. It's especially obvious in a movie scene that's filled with action. If your room issues are addressed, you'll hear dialog crystal clear.................... even when all hell is breaking loose in a busy scene.

You'll want to research acoustic treatments. (Panels, bass traps, diffusers...etc, etc..) Broadband absorption is a beautiful thing, and by merely placing a few panels/traps at key reflection points/corners................ you wont be able to comprehend how much better your system will sound. (until after the room has been FIXED)

One of the most important upgrades anyone can make to dramatically improve the sound inside any theater.......... is a room upgrade:)

Room treatment fixed a similar problem for me. i'll back up the suggestion to look into it. Room acoustics can wreak havoc on your listening experience. I haven't had problems understanding dialogue since I added treatment.

Some movies are recorded much more poorly than others. I've realized some movies must be watched at a higher volume in order for the l/r to not 'drown out' or overpower the center.
