Eric, I'm intrigued that 'a few of' your Genelecs have developed this problem. Genelecs are much used in broadcasting because of their reliability and for several speakers, albeit active ones, to develop such a fault is, I would assume, rather rare. If they're still within guarantee get them back to the supplier asap; if not, it may still be worth getting one looked at in case you had a number of units from a batch that had a problem - something like capactitors drying out? Have they been subjected to any heat extremes?
Although the 1029s seem a bit over-specced for the job being asked of them, good reproduction of speech is surprisingly difficult, and one advantage that active speakers have over amp + passive speakers is that it is comparatively easy to include comprehensive overload protection (as the amp manufacturer knows exactly the power spectrum that the speaker can handle without cracking up) and so can weather unintentionally loud sites joining in. There are other active speakers that undercut the Genelecs, but I would not be happy to (for instance) halve the amount I spent on the speaker system, compared to the Genelecs, because I would be worried that they would not handle the transients in speech signals, or might blow when a +30 dB signal joins the room.
