Up for sale is a pair of MB Quart Model Three speakers In perfect working order. They are very musical speakers with supreme clarity and intimacy and good bass for the size.  They are very well made and the musicality from those speakers is way above the price point. The tweeters are in particular one the best I've heard, so flat and revealing all the delicacy of music without being harsh. For piano, vocal, Jazz music, I can easily sit in my couch for hours listening to them. Speakers are in great overall condition with minor nicks and blemishes from normal use.
