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).

Classy piece of scrounging there! What does the driver's impedance curve look like?
BTW, it's a pleasure to see someone's living room that looks like mine.

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 🙂

Id like to get my speakers out there and test them now. Turn them up let them play. Then after take each driver out and mesure them : O )
I've just flogged through this thread and haven't seen any mention of how the baffles sound!
(Nice cat, though.)

Great stuff Dave. Somehow the words 'recycle' and 'open baffles' always soom to go together so well 😀
How much bass do you get with those baffles (which look like interior fittings from a boat)?

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....

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)
