The company that made the LGK drivers for me has merged with another company and they no longer have access to or can no longer get the exact materials that were used in making the original LGK drivers. So they have been working on a new version but have not been able to get it done correctly. I don't think they have the engineers that they once had. I have tried several variants as well as some drivers that they thought I'd like. So far we haven't produced the driver that I am looking for.
I am very particular with regards to accuracy within the frequency response. They also can have no stored energy issues or resonances that show up in the impedance response. I'm about to my wits end with these guys, and may have to look elsewhere for new drivers.
And of course they have been closed for Chinese new year. They shut down everything for about a month over there for that.
I have been working on replacements since last summer. And I don't have a lot of the standard LGK drivers left.
