What the best 89-90 db speaker I can buy for 3k?

I need a new 3kish speaker that will be used for Classical only
in a 17x 13 space driven by a fully modded Bottlehead III pre and an AVA Synergy 450 ,225 watt per side amp.

No Maggies please, something with at least a 89db efficiency,also do not care for Vandies.
