Hi, first, thanks Charlie. That was a neat history and info but it made me try and find the amp manual in the wee hours of the morning cause I had to know why it might not be good to hook up. By the way you are the heart and soul of the vintage set and are always contributing,thanks. C Blackplate, the Audex coax foam surround must be made up of something special. I have a pair of Grado 90 headphones that I don't use that often 10 years after I made these speakers and the foam ear pads desinagrated, when I picked them up a few years ago. I got replacements from Grado. One more thing, the Vifa co-ax's have 4 separate connections,2 to the tweeter and 2 to the woofer. if I do the series or parallel wiring thing from the 2 speaker connectors on the outside cabinet to the 4 co-ax driver connections will that present an 8ohm or a 2ohm load or other disasters? Thanks you guys...Mark.
Follow Ups:
Assuming that you have a crossover for the coax driver, you will still end up with 4 Ohms (nominal) using either a series or parallel crossover.
You can replace the output transformers in the amplifier and adjust the feedback network to get a 4 Ohm tap, but that may not be the greatest idea.
Thanks, now I have the answer to my question and prevented future head aches when replacement time faces me sincerely Mark.
