Chris, Scott & I got together last Saturday with the prime purpose of cleaning up the "recycle facility" a bit, listen & tweak the FE127 prototypes, and to make an approximation of an RH84.
During clean-up Chris wanted to toss a set of unual shaped "wings" i had collected off the side of the road, to which i said i would use them for open baffles, then he asked when would i ever get at it, so i grabbed a set of vintage foster 6" with whizzer cones and tasked Scott to build them... which he did on the back of his truck.
I got them upstairs into the main system today (had to sell the drivers in what i was listening too after Scott took the bi-pole 40-1197 ML-Voigts away). These are quite respectable with a ton of room for tweakage -- including removing extraneous hardware that came with the baffles, actually cleaning them, making a better leg, and of course tweaking the driver and how it is mounted. I threw the BSC circuit from my blue & yellow Frugal-phile(tm) specials on them for a bit of midband suppression.
Looking at the baffles, i'm guessing they were actually partitions for some irregular shaped conveyance, perhaps an airplane or a mobile living facility. An atractive shape never-the-less.
I've a ton of the drivers i chose -- i score every pair of the distinctive Lloyds boxes these come out of (about 1 in 4 yeilds a pr that are an alnico variation). I typically pair $7/pr for these (5.7 USD/4.4 Euro). All other bits are salvage that was laying around and the baffles were on the side of the road (i got a couple loads as the guy was cleaning out a workshop).

Re: power hunger
Officially the Jolida has less power than the Onkyo, but sounds WAY better -- a good thing since a single output tube costs more than the whole receiver

BTW, it's a pleasure to see someone's living room that looks like mine.
good thing it was cleaned up... no static fancy-pancy showplace this house

Really quite decent... surprising bass (no deep bass) and they get a bit hard when pushed (my CD player is a contributor there). Certainly good enuff that they aren't going to get kicked out soon, and i'm going to hand pick a set of drivers (i have a drawer full of this particular unit) and modified the H out of them.

Low bass is MIA, but i'm used to that -- an XO for the sub so i can also use it in the hifi is half breadboarded on the coffee table), but what is there is excellent. Hand picking a driver & redoing the leg such that it acts as a baffle wing should help extend the bass a bit.

Some person who insisted on me holding back so he could assemble it couldn't get his head around the idea that an 8-pin package could actually have 2 op amps in it....

Someone asked for the baffle dimensions -- mirrored image pairs of course.
Now if you were going to make these from scratch, a shorter, wider baffle would probably be more sonically appropriate, but these do present a aesthetically pleasing shape.

Are you suggestting a more elegant name than $7 OBs? (they soon won't be $7 -- phase plugs coming up soon -- i'm guessing i can get a set of FE166/167 plugs to fit)
