Macaroonie, Mjcaron, et al.
Many thanks for your assistance. As of mid January 2013 here's the current state of affairs regarding replacement foam inserts for the L 100 grilles..... Only one source for these elusive little devils. Just made phone contact with Forum member Sonofagun who, also happens to operate
http://FoamSpeakerGrilles.com. Others have referenced him, but apparently the email address I saw posted contained a typo which explains why I got no response. Similar problem on his posted web address.... Sorry it took me so long to figure this one out... hey Moe, Larry, fellas
