    It's just the foam covering peeling off a little - mine have the same thing and it's only a cosmetic issue.

    I've noticed that on a lot of old SDA's. Guess I'm lucky, as mine are still perfect.

    But I wouldn't think that it's only cosmetic, as the rubber surrounds attach to that peeling foam (plastic?) piece.

    RibMaster,

    Not to press you on this, prolong the thread needlessly, etc. BUT - I'm dying of curiosity here. Any luck with solving the mystery? Since both speakers are affected it probably eliminates crossovers (or not) or cabinet structure (or not again). Would that leave amplifier, placement, perception? Did you get the Kenwood hooked up?
    Sony 60'' SXRD 1080p
    Amp = Carver AV-705THX 5-Channel
    Processor = NAD T747
    Panasonic BD35 Blu-Ray
    Main = SDA-1C Studio with RD0s, spikes, XO rebuild, rings, I/C upgrade
    Center=Polk CS10, Surround = Athena Dipoles, Sub= Boston 12HO
    Music/Video Streaming = Netgear NEO550
    TT = Audio Technica

    At the risk of derailling this thread...

    I'll have to check mine later tonight when I get back to school, but my memory is that the foam is mounted to a stiff material that makes up the planar PR itself, and the rubber surround mounts to the stiff material as well. IMHO, it doesn't make much sense to mount the rubber surround to the foam: the stiff body of the PR would not be securely held on place.

    From what I can tell, the foam is there to dampen the PR a little, not for structural reasons, but I could be completely wrong.

    The outer cover of one of my PRs lifted a little; I glued it back down years ago with 3M Weatherstrip Adhesive (the yellow version--it's what I had in the garage.) Yes, there is an underlying "structure" that it attaches to.

    Weatherstrip adhesive is inexpensive; and available at any auto parts store. Gearheads call the stuff "Yellow Death" because if you get any on you, it'll be there until it wears off. I suppose ANY decent contact cement would work as well.
