What would I gain/lose?

I’ve been running an unusual setup in my second system. It’s a stereo setup 90% used for watching television and 10% streaming. I use two center speakers—Dali Opticon Vokals, driven by a Cambridge Audio EVO 75. The reason for the two Vokals is as follows: speakers are mounted inside a large Salamander cabinet with provisions for a wide Soundbar (56” wide). I’ve tried regular speakers inside the cabinet and they sound boxy, even with acoustic foam and stuffing everywhere. The Dalis sound excellent to my ear—they are front ported and designed for such an application. They also feature a hybrid tweeter that the L/R version don’t have.

the downside of course is that the speakers are only 4 feet apart. I’ve been thinking about standmounts (listening 10 ft away, small room). So I would gain sound the but lose the wide dispersion I’m getting from the Vokals. Again mostly these are used for video so dialog is important.

what say you?
