H/K changed the links and for a while we had a workaround that seemed to work. For quite some time I've been unable to access anything worthwhile. Is it possible to recreate them from what members have downloaded? I doubt Samsung would care. If they had any intention protecting or preserving them they'd have already figured out a way to monetize them.
It's a shame that other sites have better coverage of JBL manuals and specs than this one. Wasn't always the case.
