Years ago I came into possession of a couple of speaker cabinets which I didn’t open up until recently. They contain an AK 121 Vitivox woofer and a GP1, 550Hz 3-cell horn, using a Type 1000 ‘Dividing Network’ 233 by Vitivox. They are all in exceptional shape cosmetically. Do you know anything about these and do you feel they could be incorporated into any semblance of a good speaker result?
