Pure Audio Project open baffle speakers

I was interested in open baffle myself, thinking about the PAP, then I found a set of Emerald Physic 4.8s at less than a third their normal price on Audiogon and bought them. Should get them in a few days, also orders a Rhytmik servo sub to go with them. GR research has an intresting speaker Dannynis working on called Line Force. Seems he’s waiting on one element of the design, one of the drivers that I guess he was happy with the initial ones, before he offers it. New Record Day was describing the sound when they ineterviewed Danny at his place, and once they come out I’d like to try those along with his OB triple bass subs.

There is a company that builds cabinets and puts together speakers using Danny’s parts. I have emailed him a few days ago myself, but have yet to hear from him
