jason str Posted August 29, 2016 Share Posted August 29, 2016 Part numbers were different between the two passives. Hope you can find a replacement. Quote Link to comment Share on other sites More sharing options...
dtr20 Posted August 29, 2016 Share Posted August 29, 2016 This is what Tom's passive looks like. Is this salvageable? We know about simply speakers, but I heard they are not taking orders. If this is the case, are there any other companies you guys can recommend to rebuild this passive? Quote Link to comment Share on other sites More sharing options...

mustang guy Posted August 29, 2016 Share Posted August 29, 2016 If you have the right measuring equipment and 1 good chorus, you could put in a run of mill passive from PE and add weight until you get the tuning as close as possible. The trouble with having a different Thiele/Small spec on the passive is that is made for that box and that woofer for a specific tune. You can increase the mass of the passive's cone but you cannot decrease it. You also cannot influence how stiff the passive is (CMS). It's a tough problem, but without the T/S spacs on the Chorus' passive, you are flying in the dark without instruments. Quote Link to comment Share on other sites More sharing options...
mustang guy Posted August 29, 2016 Share Posted August 29, 2016 In a way, that passive looks like a K-33. Could it be possible that they used a K-33 without the magnet as a passive? Do you have any pictures of the back frame and are there any little numbers stamped anywhere?? Here is my K-33 redo thread. The pics look a lot like what you have there, but I can't see the frame etc in your pics. Wouldn't that be a stroke of luck... Quote Link to comment Share on other sites More sharing options...
