Sansui S-M90 Speakers

Those are just early 80&cheap fiber board/press board built speakers.but they are surprising by their sound.and not by their look! First time that I test those Sansui S-M90 speakers with this Sansui 600L receiver.both comes from very different eras-the receiver came from 1969,and the speakers were made at the early 80&to last Sansui VS cheap,money bleeding Sansui.but-that odd pairing sounds great to me-the warmly sound of an early transistoried Sansui which decrease the harshness that those speakers sounds with other,more modern receivers/amps.
