Default $7 open baffles...

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.

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

I've just flogged through this thread and haven't seen any mention of how the baffles sound!

(Nice cat, though.)
