After much hesitation, I’ve decided to part with these cabinets. They’re classics, and you can tell, although I did refurbish them when I got them. The grille got a solid coat of paint, and I replaced the internal insulation with foam instead of the fiberglass-like stuff that was in there. The enclosure could still use a bit of love.
I’ve fitted them with NL4 connectors, since that’s more common these days. Pins 1+/- go to the drivers; 2+/- is for through-connection. They work fine, and I even have an original spare driver (as far as that’s possible—these things came with different RCF drivers over the years, as far as I know).
Price is €1000 for the set. More photos can be arranged. Pickup in Utrecht.
