Mirage OMD-15, available in black or rosewood. These were originally designed to sell at $2500/pair, but Vann's, who's an authorized Mirage dealer, sells them at $1K/pair in either finish. I paid $1700 for mine two years ago and don't regret it because of the value I've received.
As to your room-filling needs, my living room is very similar to yours--13.5 x 19 ft, with 15' tall cathedral ceiling, set in an open architecture living space. Since the entry hall is part of this living space, the immediate space is more like 20 x 19 ft. plus the arched ceiling.
Anyway, I have been using a pair of Mirage OMD-15s in a primarily LP-based 2-channel system in the living room for about two years. The OMD's are omnidirectional, so they are particularly adept at energizing the entire room and living space. Because the speakers were designed to interact with the listening space, the timbres and soundstage are like live music. I know, because I got married in this living room and we had live music. These speakers match the timbres and how the source music interacts with the room acoustics with notable accuracy.
They are also not power hungry. I power mine with a modestly priced Onkyo A-9555 integrated amp, rated at about 85/170 watts/channel into 8/4 ohms respectively. I got the amp from Amazon a couple years ago for under $500. It's an excellent match for these speakers.
