Huge Alnico square driver id?

Uk Speaker freak ::..
Hi everyone i have recently acquired a very unusual speaker set and i am struggling to find any info on them The main driver is a square perspex frame 9.5" with a huge Alnico 6" magnet the cone and coil are damaged. i also have four of the horn tweeters as shown in the pic, no markings other than 8 ohm tweeter on the side, the large speaker has no make or model at all. Very good engineering craftsmanship has gone into this one by the looks of it.
If anyone has any idea what so ever i will be very grateful!

That looks very much like a homebrew driver. No manufacturer would make a basket out of perspex parts -- to much assembly required. Looks like a phenolic cone and a flat foam suspension -- am I seeing it correctly?
 
Holy schnikies. Those clear plastic legs do not look sturdy enough to hold up that huge motor standing still, let alone playing. Anyway I hope someone has some info on them. So no numbers or anything? If there were, they might be long gone under the rust and corrosion.
 
Good point Nat, we were posting at the same time. Maybe they are DIY. In which case the motor itself might be identifiable by somebody, just from looks, if you forget about what it's attached to.
 
You are right toxcrusadr the legs do not look strong enough but they seem to hold well, as you can see a lot of time and effort has gone into this speaker which made me think it may be a prototype or early factory made. The other matching cabinet had a Lowther 6mk1 both the Lowther and this speaker were set up as mid range speakers with the horn tweeters as the top end. Each cabinet is a sealed design around 5 feet tall with an unusual RCL 12" 12404hp 8 ohm bass unit, the bass drivers also have huge magnets at 10" in diameter the only description on them is 101db sound reinforcement speaker resonance 31hz
These cabinets are heavy!

The surround appears to be leather could possibly be a caveman speaker :yes:
Thanks for the help guys, home made is looking likely.
 
Leather suggests VERY old. I have a radio made in 1928 with a Utah speaker with leather surround. Not that it's that old, it would have to be a field coil speaker, but I'm guessing 30s-50s for the driver itself (not including the plexiglass, not sure when that came along).

Weren't there some 1950s era British drivers that still used leather?
 
Definitely looks funky but this was Final Jeopardy, I'd guess it was an Electrovoice driver that had been... ahem... modified.
 
Chamois cloth was used for surrounds which that driver has. I've had a few, Japanese & English manufacture.

The driver looks like it was meant to fire up. Considering where it is, could that have once been in a Voigt?
 
I'd guess the drivers were made by a company named Racon. The phenolic cone of the woofer was designed for high humidity environments, such as on board a ship. They don't turn up on FleaBay very often, but when they do they are always interesting to look at.
