Emotiva have passive speakers. I just mentioned the review to show they can make decent gear.

The Martin Logan, Motion series is an affordable line but I'm not sure what price point they start at.

I used to work at a store in the 80's that sold Boston and I liked them back then, several years back I heard some again and was pretty disappointed, thought they were very dull. They may have improved since then though.

Keep in mind much of any of this is general, listener preference and will definitely depend on your room and gear.
