Thinking of purchasing the UniTheatre, my wife caboshed the larger set ups I was looking at for my fronts. If I pair this with a sub such as Velodyne VX-10 is it going to compromise my movie experience drastically as apposed to going with 2 Polk R50 towers along with a CS center? Over all budget for L/C/R and sub was $450. I found a used UniTheatre keeping me under my budget at $300. Any thoughts?
