dtr20 Posted October 27, 2016 Share Posted October 27, 2016 Has anyone ever heard of these speakers? It has a 10" woofer, a 10" passive radiator, 3" mid-range, and a 1" dome tweeter. II know they were made in Poland, that's pretty much it. I'm in the process of repairing/restoring a pair of them. I have no clue how they sound, I'm refoaming the edges of the woofers. Also, if anyone has a clue to an approximate value, that would be awesome. Thanks Quote Link to comment Share on other sites More sharing options...

Moderators dtel Posted October 28, 2016 Moderators Share Posted October 28, 2016 I guess no one heard them. Probably sound fine, a little laid back if anything. I would have thought with the 10" driver and passive it would have went a little lower than 40. Quote Link to comment Share on other sites More sharing options...
eska Posted March 23, 2017 Share Posted March 23, 2017 (edited) Hello, Those loudspeakers are one of most popular speakers made in Poland i 70's/80/s. Those were first polish speakers made in "hi-fi". You can find a lot of information using polish name - Unitra ZG40c ("ZG" means "Zestaw Głośnikowy" which means "Loudspeakers set" ) 40 Watts, version "c") - typing in google polish name of them, you will find A LOT of informations. Woofer is GDN25/40/x (GDN - Głośnik Dynamiczny Niskotonowy = Dynamic Woofer Loudspeaker, 25 cm diameter, 40 W, x Ohm) mid - GD12/15/x (Głośnik Dynamiczny = Dynamic Loudspeaker, 12 cm diameter, 15 W/x Ohm) twitter - GDWK9/40/x (Głośnik Dynamiczny Wysokotonowy Kopułkowy = Dynamic Loudspeaker Twitter Dome 9 cm diameter, 40 W, x Ohm) GDN25/40 firsty were on Pioneer license, then it was Unitra TONSIL. Good polish loudspeakers from 70's/80's. Edited March 23, 2017 by eska 2 Quote Link to comment Share on other sites More sharing options...

My JBL 4311 speakers (pro version of their Century L100), had a ported 12, and were rated to 45hz. Still have lower bass than my Heresy IIs, although not as tight.
