John Reiff Posted July 14, 2020 Share Posted July 14, 2020 The original Forte's woofer had a corrugated paper surround. The Forte II has a rubber like surround. The Forte III has gone back to the corrugated paper style surround. Just out of curiosity I would like to know why the changes back and forth.

Moderators Travis In Austin Posted July 14, 2020 Moderators Share Posted July 14, 2020 You would have to ask @Chief bonehead he is a bona fide KGI employee and Project Manager/Acoustical Engineer for that Heritage upgrade and the other Heritage upgrades. He has been real busy of late, so it may be awhile before he responds. When he does, sometimes he can say, other times he can't. Quote Link to comment Share on other sites More sharing options...

WMcD Posted July 17, 2020 Share Posted July 17, 2020 Is that correct that the Forte II had a rubber surround? I don't recall that on mine. I had to sell them, which after all was not really necessary. WMcD 1 Quote Link to comment Share on other sites More sharing options...

John Reiff Posted July 17, 2020 Author Share Posted July 17, 2020 Yes, my Forte IIs have a rubber like surround. As you can see they are starting to get a white dust like substance on them. I am wondering if i should apply some type of Armor All or other type of protectant 1 Quote Link to comment Share on other sites More sharing options...

Let it dry and repeat if necessary. Quote Link to comment Share on other sites More sharing options...
John Reiff Posted July 17, 2020 Author Share Posted July 17, 2020 billybob: Thanks, I'lI try the white vinegar. Still, I would like to know why the switch back and forth from the original Forte's corrugated paper surround to the Forte II's rubber like surround then back to corrugated paper on the III's. Just curious. 1 Quote Link to comment Share on other sites More sharing options...
billybob Posted July 17, 2020 Share Posted July 17, 2020 Maybe the historian can help sort that one and as far as cleaning, there are other things available. Main point is clean and then why not just a light coat of something made for rubber like materials. Make it more supple I suppose. Quote Link to comment Share on other sites More sharing options...
Frzninvt Posted July 17, 2020 Share Posted July 17, 2020 NO the original Forte' had a inverted rubber surround on the woofer not corrugated paper. You might be thinking about the Quartet. 1 Quote Link to comment Share on other sites More sharing options...
JRH Posted July 18, 2020 Share Posted July 18, 2020 Frzninvt is correct. The original Forte also had the rubber surround, a rubber-edged cone from Donal that I spec'd. The cone remained in the Forte II, but I don't recall if there were any other minor changes to the driver. The corrugated edge is treated and sealed cloth. It came into use on other Klipsch pro products subsequently, so Roy was very familiar with it. Also, Donal is out of business, so rubber edges are pretty much the purview of Muller in Germany. Not exactly economical. 1 Quote Link to comment Share on other sites More sharing options...
