Looking for someone who can and does repair these "non-standard" vintage German types (or who is willing to advise)
Sold as stand alones as the RB46, labelled "5403" if they were supplied with a receiver or radio
I have a pair I just re-capped, very impressive little boxes.............BUT, I have an issue with woofer cone resonance and it's bad, ruins the speakers
Using warble test tones I have identified the main problem as being between 63-80Hz; any "off the shelf" suggestions? Can't hurt anything
Fairly large oval shaped woofer, VC alignment is good and the spider appears flat and firm
Have done/checked all I can do, even treated the pleated surround edges with a little PVA (these speakers were poorly stored I think)
Very very nice sound after the re-cap, mids to highs
These are worth repairing, so my question is: does anyone here work on these types or know someone who does?
