Avant-garde speakers

Has anyone had any experience with Avant-garde speakers?  Specifically, I am thinking of buying a pair of Uno Nano speakers to pair with my First Watt J2 amplifier.  The system will be used in a rather small bedroom (15' x 15').  Also, the speakers are about 9 years old and selling for about 1/2 the new cost.  I guess what I am interested in is whether these speakers will work in this situation, and what can I expect in terms of performance in a 9-year old Avant-garde speaker.  Do they sound good at low to very low volume?  i currently use a pair of YG Carmels. Can I expect them to be reliable at this age?  Any input would be appreciated.
