Re: Mystery floor standing loudspeakers - any ideas?
You can see the rivet holes for the brackets on the long sides of the bass driver, and the matching holes part way along the brackets So the mystery shifts to why the brackets are so much longer than necessary.
Anyway, the speakers are cobbled together from what someone had to hand. Difficult to criticise, because I did things like that when I didn't have much to do it with. David

It's a Frankenstein build for sure.

Ahh yes, I see what you mean, vidjoman - well spotted!

Re: Mystery floor standing loudspeakers - any ideas?
Thanks all, much appreciated.
Yes, 'Frankenstein' builds makes sense, and although I can't take the front covers off, I can feel that the baffle cut-outs don't really line up with the drive units. There is possibly even a third hole, suggesting whatever the hell the 'Symphonie' cabinet was, it was meant as a three-way? What to do with them though? Probably donate them to the Habitat Restore! |

Re: Mystery floor standing loudspeakers - any ideas?
These still puzzle me. Apart from a bit of BAF wadding in the base, there appears to be no real damping in the cabinet which looks like a non-ported enclosure. These large EMI ellipticals were primarilly designed for use in reflex cabinets.....??
I bet these sound really "boxy".

Re: Mystery floor standing loudspeakers - any ideas?
If they sound OK with the cabinet backs off, I’d be inclined to leave them that way rather than cramping the style of those rather good big EMI elliptical units by enclosing them in a small volume and hence pushing up their fundamental resonant frequency pretty horribly.
