Expression 13A Bass Driver works panel silent

[Allan Rich]

Hi Guys,

Just joined the group, and this issue came up.

Hi my left speaker has a silent Panel, woofers work.
Tried swapping from right channel, still silent.

Any possible fixes or do I need to have a tech investigate?

Thanks for any advice.

Does the green power light turn on? Assuming you ruled out upstream pre/amp problem by swapping, next step would be to contact ML for advice. It could be something as simple as a loose connection, or alternatively a bad power supply.

Thanks, all light are on and bass unit works. Sending for service Monday.

On older speakers ,sometimes the panels have slowly slipped down with gravity. If they go far enough they can damage the wire that runs to them. Martin Logan even makes clips that customers can install to stop it. Don't suppose the newer speakers can still do that?
