With average use how long for panel replacement ML

I concure with Magfan...can you say delamination? With the Martin Logan's, you can buy a new set of panels which are pretty easy to install yourself. When a Magnepan goes down, it's pretty much a complete and messy internal surgery to repair yourself or a very expensive trip, (freight) to the factory and back.

In general, it's pretty much agreed upon, that every 12-15 years you should replace the panels with normal use. The cost of replacement panels just skyrocketed, so I would check with Jim Powers, (I agree, Jim is a GREAT guy) to see how much the panels would be for your model. You can tell the manufactered date of the panel by the serial number of the panel, see link below.

I also agree that new panels equal, more or less, a new speaker. New panels do need to break-in and will need to be replaced in pairs.

No matter which model you buy, you will enjoy them. They really are terrific speakers.
