Old Grundig Fullrange fun - Page 2

haven't given it much thought. maybe use the front panel/baffle as nothing more than a dust cover. i would need to find a good driver(s). then the question of how far away from the org. design to go or will it ever have antique value as is? don't know if i'll ever get around to it.

93db 4Ω so i assume the 8Ω version is 90db. hard to tell with the grill on but looks to be fullrange/wizzer, would be interesting to see t.s. specs and plots. i'm going to add them to my fleabay saved search option.

Just been in another part of this forum where there is a discussion regarding the use of curved enclousures in modern loudspeakers. It's an eye opener to see that this technique has been captured in such an old loudspeaker.

BTW. You could improve the sound quality by adding dampening to the cabinet walls, better acoustic dampening. Block off the port. Finally, install a passive equaliser (~2MH/2uF) in series to achieve as flat a response as possible.
