I'm about to recone a K130. I'm hoping to get as close to the original D130F tone as I can. I read a comment by Harvey Gerst that the D130F surround was coated with heavy (high viscosity) oil, not dope. Has anyone tried using heavy oil? How heavy?

As previously directed, Ken ( Upland Loudspeaker ), makes a fully assembled recone kit that'll give you performance as close to the original as is now possible.
Ken is currently moving shop so he may be a little hard to get hold of right now.
PS; Can you please provide a link to your Harvey Gerst reference ? ( I think you may have misinterpreted his words about surround goop )
"It wasn't "dope"; it was a high viscosity oil we used to keep the surround from dying out."

I don't need a kit, I already have the parts. I just want to know what viscosity of oil to use.
