lots of good recommendations already.
I would suggest the Vandersteen 5A speakers.
Used pair probably $5 - $6K. Built in subs so you can dial in the bass.
Nothing at this price will beat the sound they produce.
Here is the real benefit, Vandersteen supports their speakers and they have available parts for them if you should ever need them. You can get shipping boxes from Vandersteen also if you need to do so.
With the right amplification, you will be in heaven.
Happy Listening.
