Hi Steve;

The problem could be a couple of things. Power supply or Midrange like Bruce said (doubtful on the midrange though if the problem goes away after warmup) Could also be a DSP or amplifier problem. The only way to know will be to get the panels here so that we can duplicate the problem. There is also a remote possibility that the problem will not show up here, many moons ago we had a similar problem and it turned out to be that the panel was shorting out one of the PSU wires when it was screwed down. (poor installer problem). If that happens then we would need to get the entire speaker here to be able to sort the problem.

This is why Meridian always wants you to use a local dealer or at least a dealer who is willing to stand behind the sale and support you if you have an issue.

Best best is to get the dealer who sold the upgrade to get the panels removed and sent here for evaluation, If that is not possible then you will need to get a local installer to come in to remove and re-install the panels while they are serviced. That will not be covered by Meridian as an expense.

Best
