From AVSForum:
The Revel Voice has the same 4" midrange.
I called Revel and ordered two replacement midranges for $280 total since they recommended upgrading them in pairs.
A couple of years ago, it took 8 months to get the Voice Center Channel midrange since they moved the production (to
China, I think).
After pressing on the right-midrange it exhibits the same scratching noise that my Voice midrange did. Apparently, the glue (or something) breaks down and bollixes up the works.
From an earlier call to Revel, I was told that all Voice midrange drivers will fail eventually.
So this problem may not have been my fault.
I have a couple of EE friends that will assist in the procedure and my surgical sheet with a whole cut to expose target area
Thank to all for the support,
Rich
