I would look for either the Infinity Primus line or the JBL Northridge series. Both have discontinued some models that can be picked up cheap if found. I have both in my home and they are very good bang for the buck speakers. I was able to buy a couple pair of the JBL E-20's for $40 a pair a year or two ago. The Infinity Primus 150's should be cheap too if you can still find them.
