Reme, I’m already looking at the rockler ones :)

MyFathersSon, you may try and see if Dynamat would work on the underside of the plate. Dynamat is sound dampening material I would use on car doors to dampen vibrations from speakers for car audio performance. You can probably get the same stuff under a cheaper generic name. Dynamat is sold at Best Buy and a lot of car audio stores or online.
