That is a pretty big room to fill with sound for 1K. None of the Totems that you will find at that price will do it. I tried a pair of Forests in a 26X16 room for a weekend and they definitely weren't enough. Neither are the smaller Spendors going to do it. You will have to go to at least the S8e, and that won't happen at your budget. I think you are either going to have to live with the limited dynamics and absolute volume you will get with the size constraints you have stated. Or else go with a larger more expensive speaker.
