There is no information on any of these speakers. The cross over is the simple capacitor resister type. I have never seen a dust cap on a driver like that before. Ec20016 is stamped on the outside of the speaker rim. Perplexed garryThey do look alot like either older Monitor audio or some older B&Ws?
The cabinets are probably resonant and not worth putting good drivers into without some work. If the cabinets are less than 3/4" MDF I wouldn't bother.Yea nobody seems to know what they are. Time for a new home project. Any suggestions on speaker and crossover replacement? What about speaker insulation?
