I, too, have a pair of Scan-Dyna speakers that were given to me. If it weren't for the fact that they came in their beat-up original boxes, I'd have had no idea what they are. However, the boxes identify them as A20's. The cabinets measure 25cm x 25cm x 43cm. I have been unable to find any information on them, though I did find a spec sheet on the Scan-Dyna A25. I replaced the ancient Jensen 12uF electrolytic cap in each crossover with a metalized polypropylene cap, but I have not yet run them long enough to really be sure I have the cap fully limbered up. Oddly, these speakers have integral speaker wires (the originals); there are no connectors on the backs.
