Green Mountain Continium 1.5, anyone heard these?

I am putting together a vintage system. Just found on his site a pristine Sansui AU717 and TU717. Next I will add a Sota Star Saphire to a Luxman PX 100. I will be auditioning a pair of 1.5's Saturday and will try them with the Sansui but I am curious if anyone here has any experience with this manufacturer. I had never heard of them untill a local dealer had a pair for sale and spoke glowingly of these speakers. Before anyone thinks agenda, the dealer is also a good friend. I was drawn to the speaker because their looks remind me of good old Dahlquist DQ6's and DQ8's. Do they sound even remotely like the DQ's? Just seeking impressions from experienced folks.
Thanks!
