Sound bar in a box . . . can't understand dialog.


We have a large credenza in our bedroom that houses the TV, video gear and sound bar (a modest Visio) facing the bed. It's become our favorite movie theater. Think a 4'x3'x8' box with doors on front. The "booming" caused by the interior reverb of the credenza box makes any dialog unintelligible.  Tried moving it out a bit when open (a pain) as well as adjusting out lower freq.s and boosting treble. No luck.  

Any suggestions on something more creative would be much appreciated!

ALERT! Wife is an interior designer so anything that does not fit inside box is not acceptable.

I sorted out my mother's TV sound with a cheapo Logitech 2.1 computer speaker set. The sub has its own volume control, which makes balancing the sound fairly straightforward.

Personally, I put the TV through my hi-fi, and am very pleased with the results.

I did something similar, threw together a patchwork of left over mini-monitors with an old Kyocera receiver.  The monitors are attached to the doors so they swing out of the credenza cavity and don't excite the volume like the soundbar did.  

or get a panasonic oled tv,,, the whole tv itself it the  speaker panel.
works great and wife friendly.
