Hi! I own Klipschorns and I was thinking about cabinet vibrations (and the resulting colorations...) for quite some time now. What I intend to do is bolt thick steel frames (say about 1cm thick...) on the side walls of the bass horn. This will theoretically make the panels vibrate at a higher frequency and, thus, partially solve the problem. And I say partially, because there is also the front panel...which I wouldn't touch, for aesthetic reasons. Would greatly appreciate if someone with engineering knowledge, could calculate for us the best - and lighter - bracing pattern...

When I rewired my 1999-vintage KH's, I noticed that the wiring of the squawker - in both units - was reversed: i.e. +wire from crossover went to -terminal of squawker. Checking the AK3 schematic, I found that it shouldn't be so and I reversed the connections... Although everything leads me to believe it has been a wiring fault, it could also be so just to correct the phase of the squawker vs the rest of the speakers. Something, I understand, quite difficult to check by ear alone. Might also be that my AK3 schematic is an older version... Any ideas somebody?
