I listened to a pair of these in a dealer's room last week -- the room was probably a little wider than yours and certainly the ceilings were higher (probably 10ft) but it was not a longer room -- I thought the X-2 looked so imposing in that space that they could not really work but they did, and the dealer told me he has sold them to others who have similarly sized rooms. I did not hear overwhelming sound at any level and they focused really well at the listening seat on most recordings. Closing my eyes I would say this is probably best sound I had ever heard, a truly holographic central image on a solo voice/guitar record. The adjustment possibilities on these speakers mean that working with a trained dealer is a must to get them set up optimally for your space but for the price, you have every right to expect these being tweaked to your total satisfaction anyway. I cannot get over the look, which I find so ugly, you really have to close your eyes but the sound is wonderful. Worth the price? That's a personal decision, but for me, at $100k more than many other great speakers, they are a hard sell.
