I agree with a number of the suggestions, particularly the older Vandersteens. Another warm-sounding speaker I would suggest that might match your requirements would be the Annandale Acoustics A25, which is something of an homage to the old Dynaco A25. You can see their website at http://www.annandaleacoustics.com/. We had these demo'd to us at an NJ Audio society meeting and, while the reaction overall may have been mixed (it usually is), I think most would agree that this is a warm-sounding speaker. IMHO it was very enjoyable to listen to, particularly with rock and vinyl. The company is not well-known, but it is a good quality product that they offer.
