Decent sized room.. Ascend sierra1 is a great choice- Sierra 2 is due out this fall with a rumored Raal tweeter and improved woofer that might be worth the wait.
Also, the Nola boxer 1500.00, and perhaps the Zaph ZRT with the Lee taylor cabinets, about 1750 assembled and tested. The Zaphs are a DIY design featuring a Scanspeak revelator woofer and aircirc tweeter. Normally a tower design, but Taylor will custom build the speaker as a monitor.
One more idea is the Selah SSR, 1695.00, available ported or sealed. Kit or assembled.
Assemble it yourself or have it done for you, these are outstanding values considering the quality of parts and their respective designers.
You may benefit from a dual sub setup to smooth bass response throughout your room.
