Vintage iconic IMF monitor bookshelf speakers in rare factory black finish. This gives them a modern look even today. Loads of info to find on the net. These are audiophile grade. Tested very good. Drivers works perfectly. Totally original. Mid units are normal and funny looking surrounds have no effect on the sound (closed & dampt) Pictures are part of the description. Excellent in my opinion, just little signs of use. Matching L + R set!
