Does any one know anything about doping? I have a Z Best with P12Z's (Silver Bell 30 watters) and it seems like they are undoped (I don't see any goop). I get a lit of buzz when I turn my Mazerati up to about 9-10 o clock but onlu on certain notes. Is this cone cry?
I want to be able to turn my amp up to the point where the tubes and speakers are responsive. I don't use super high gain or play often above the 12th fret. I'm looking for Townshend tone circa '68.
Should I have these doped if they are not already doped?
Thanks

i'd ping Ted Weber on this. i had the same speaker as yours but in the ceramic version and it was doped as i recall. you can easily tell if yours is or not by looking at it. if you have some sticky stuff around the outer diameter of the cone, then it's doped. i believe DAP/Weldwood contact cement in the red/black can should do the job.

From the Weber site:
Doping is the shiny goop you see on the surround of a speaker. Besides extending the life of the surround, it also acts as a shock absorber to help keep the cone under control at higher volumes. The downside is that it also dampens cone vibrations and therefore reduces the potential character and texture of the speaker. If you are going to bend/sustain notes in the area above the 10th fret on the high E string and at high volumes with heavy distortion, then you need the doping to help prevent ghost notes and cone cry that could result from the extreme cone vibrations. Otherwise, I would get the speaker undoped. Many players prefer the raw, undamped tone of the undoped speaker and they learn to modulate their finger pressure when noting in the area that causes cone cry. Pre-Rola Treatment For this doping, the cone is artificially aged and chemically treated. Vibration dampner compound is also applied to the cone body and surround.

Do I know anything about doping? I'll take the 5th. Gave it up years ago

I think they asked Floyd Landis that same question.
