Speaker recommendation for married couple

Vienna Acoustics. More in line with with the SF speakers sound but not as warm. Never bright. Amazing furniture finish. Much cheaper than SF used. At least worth a look.

Again I will say Vienna Acoustics Mozart Grands. Why???? Because they are in the same family sound wise as SF. They cost a whole lot less used generally than SF. IMO you pay for the finish and looks for SF speakers big time. 

The Mozart Grands also have deep bass for a small floor standers. They are able to completely disappear. They are also 4ohm so a 70 watt amp that doubles is plenty enough power so you don't need to go crazy. They are in you price range used. The finish is better than most speakers in the price range. 

If looks are not an issue (not that they really look bad just not a show stopper) I would go also look at Golden Ear speakers. The ribbon tweeter are very musical and never sharp. Plus you get more bass than you would expect because of powered subs in the speakers. Also you can adjust the bass level allowing you to tone down bass in a smaller room. 

again I will
