Are the Bozak compact monitors mb-80 keepers?

Hey Guy’s, so I picked up some Bozak mb-80 compact monitors and I understand that they was the last go around for Bozak before the doors closed. the cabinets are very heavy and i was wondering if anyone out there in
audiogon land has had them and how did they like them? what type of amp will make them dance? I’m wondering if the metal cone woofers are a gimmick , are they rare as someone told me. what is your opinion about these little monsters.
