Sound bar for Dialogue

You're not likely going to find something like this.  It could very well be that your room needs acoustic treatments.  Try putting sound absorbing panels on the front side walls.  The sound reflections can easily cause vocals from the sound bar to be extremely hard to understand.

I use ZVOX and it is so much better than the TV’s built in speakers. The ZVOX has multiple tone controls including those for bringing forward the ’speaking’ range’. They have multiple models and are inexpensive.

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.
