Sound bar for Dialogue

Thanks, Newbee.  Can you elaborate on the best model for dialogue, or are all ZVOX models great for dialogue?  I am using bookshelf speakers which are an improvement, but still some programs have dialogue that is less than clear at times.

Thanks, auxinput.  Given that my tv is in the living room in an entertainment center, acoustics could be the problem.  But wife acceptance factor does enter in.  

Sound absorbing panels worked best for me. The more drivers you have, the harder it will be to get the clarity you desire.

I always agree with having appropriate room treatment as being essential for clarity and tonal balance.

Still, I think having a sound bar is such a great feature to simplify a high system which shares space with the TV.

rdoc, The Zvox I referred to was not incorporated into my 2 channel audio system which I use exclusively for music. I only use the Zvox for TV (in different rooms) and it replaces the 'full range' (haha) speakers in the TV. Great for what it does but I doubt that it would be better than properly driven audio speakers. Re different models, size = bass performance.
