By the standards of time, those 52.2 speakers measured well I should add. If I remember correctly. It's been a long time since I saw measurements on them.How they stand these days, compared to modern speakers, I don't know.Ha, that may be true, but he's not big on marketing - the way he's sitting in that chair with that expression makes it look as if he's criticising his own creation, ha!
Attached picture, measurement (FR at top of graph, distortion curves below)of a couple of his models from the 70s: OA12. Plus picture of a couple of these OA12 with upgrade kits. Kit developed by Ingvar Öhman (disciple of Stig Carlsson). Öhmnan which has its own Ino/Guru speakers:
Or if it was another disciple, Peter Steindel, Bremen speaker, who produced that OA12 upgrade kit. I do not remember.
Edit:
Modern sound ideal has probably passed a couple of speakers from the 70s, but I would have liked to listen to some OA12 with that upgrade kit (new speaker elements and crossover filter).
