[AG-TECH] Room node speaker suggestions?

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.
