Thanks PDR - your second link is his electrostat build thread and I don't see any sub stats there.  Your first link is to his Ripole build thread and the only stat I see there is that his particular Peerless drivers can reproduce 17 Hz.

Hank, "stat" means "electrostatic."

I'm curious as to why you want to build a ripole? (Instead of e.g. a W frame etc)

[Hank]

OIC - yes, I knew he built a pair of stats - been to his linked site - he did a great job.  Why am I considering Ripole?  Same reason I'm considering all of the "origami" OB sub designs.  Mainly, it looks like the smallest implementation.  However, Danny says that because of the large unbraced panels, Ripoles are "buzz boxes"     Anyway, I may wind up with a W frame - more reading to do about DIYers' experiences with the various designs.
