I have a center channel speaker like this one. http://www.soundstage-audio.com/3dc.html The problem I'm having is that most of the time I have a very hard time understanding dialog coming out of it in blu-ray or DVD movies. I have tried everything. Checked polarity. Balanced system with an SPL meter. Turned the center +3 or more above everything else. The speaker sits just below the TV at about chest level with it aimed towards my face. It isn't sitting inside a cabinet or anything like that. Speakers are timbre matched. Tried a new speaker cable. Checked for a blown tweeter. I'm at my wits end and it's frustrating. To the point where I turn on the captions. The speaker sounds like when your talking through an empty paper roll tube. Could it be my amp? Harman Kardon AVR140 Question is would upgrading from a center with 5.25 woofers to a center with 6.5" woofers like my L & R mains have possibly solve my problem. Like these? http://www.soundstage-audio.com/3dc2.html On a side note. These speakers aren't that common. Sold by a Canadian company. Do these specs tell anything about them? Over all the system sounds good, just not my center.
