Jean Marie Reynaud is a small but quite established French "createur d'enceintes"; he has a web site at
www.jm-reynaud.com.Me, I wasn't that impressed when I got to listen to a couple of his creations, but that was in show condition.
I think you could try a search on this Forum, there was a little discussion some months ago, regarding Offrandes and Trenté.
JMLab is an altogether different affair, JM derives from Jacques Mahul, the founder and owner of JMLab and Focal; I think this is the biggest French owned loudspeakers manufacturer.
