I guess what it sounds like you're looking for is a speaker with a rolled off high end. Nowadays, even modestly-priced speakers have pretty decent high ends, and I don't know of any audiophile speakers that are really rolled off (almost by definition).
In addition to causing too much high frequency energy, a "BRIGHT" room can result in a high ratio of reflected to direct sound, and this can hurt your imaging and sound staging, as well as sound tizzy. I would recommend you consider damping the room down until it isn't really bright, then getting a good audiophile speaker whose sound you like. If necessary, you could add a room equalizer to smooth out the response. I know this sounds like you're taking away just to add back, but I really think this is the right approach.
Trying to buy a crummy speaker that will just exactly compensate for unquantified, unmeasured, bad room acoustics is probably not the way to go.
