And i changed several time metal domes for paper ones, with *always* better results.
I still have a grocery bag full of new RTR mid and tweeters. but life is too short. Too much to do and too little time. ..... even though I never get to bed before 12-1am for decades!

The figure is 85dB for 40 hours exposure per week - see your EPA and most national safety/environmental bodies. However this is NOT a safe limit. It is a limit that has been accepted by industry that accepts that ~10% of the work force so exposed will suffer significant hearing loss i.e. the economic cost of that percentage of the work force having hearing loss is estimated to be less than the cost of reducing noise levels. Think Ford Pinto...
The safe level is usually quoted as 70dB which is quiet in the context of a lot of music listening.
I got those speakers at a discount and I was told by several people they were a steal, something about being similar to some famous speakers that were no longer in production. At the time they were the best speakers I had heard, because they were almost the only speakers I had heard. I now have a 3-way center channel (found inside a forest) that seems better in some ways when I point it in the opposite direction from me. Otherwise my ears bleed. Must be the resonant tweeter diaphragm.

John, I think you'd (and most other people too) be suprised with the ideas people come up with. Some are to nutty the surprise id doubled when they actually work.
About a year ago, a friend who secializes in speakers and nothing else decided to try to make an audio speaker using drivers and systems as used in cars. So he picked up some JBL units, those 8" bass units with a dome tweeter on a metal bar right in the center and made an airtight speaker box. I teased him all along the way, but in the end, he created a pair of medium size speakers which were hardly the High End, but actually played some good music. Easy on the ears, pretty efficient, with a decent downward extension. Surprising, for me at least. Not ideal, but not bad at all.

Ay, Richard, you lucky devil! In the mid 70ies, I managed to wiggle my in the Radio Belgrade studios. At the time, it was more or less a two company setup on a professional level, anything passing electrical signals (except a few odds and ends) was marked as Studer, and if it played any music it was marked as JBL. That's where I got to hear those big JBL multiway boxes and I was truly bewitched. That's where I fell into an everlasting love of their relatiely models 4312 monitors, which may have been the forerunners of their classic Century L100 model, which made JBL a household name, but that was it, I was hooked.
The fact that I named my current speakers 1041 is a sort of honouring that box. But tat was in 2002, 27 years later, and my mid cone will take 100W of electical signal in the 500-7.000 Hz range (says the manufacturer) with only 6 dB/oct XOs. If you were saying that good power handling is essential for a midrange driver, I couldn't agree more. They need to stay fully composed, if not you are done.

I spent a day installing a one of those Genesis systems.
Then I gave it a crank playing Jimi and The Who...much more interesting/fun than that string stuff.

RTV silicone is soluble in wikipedia.org/wiki/Hexamethyldisiloxane..... NOVOCS® GLOSS and NOVOCS® MATTE Silicone Solvents.
Tolulene works as silicone solvent also.
You could try making a very thin solution and wick it into the paper whizzer edge to provide a damped characteristic.
Further coats could be added after the first application has cured.

The vast majority of audiophiles never get it ... that if a system does a brilliant job with Hendrix, then it will also reproduce a string quartet superbly well - it just does, not, compute ...
Yes audio blasphemy I know,The vast majority of audiophiles never get it ... that if a system does a brilliant job with Hendrix, then it will also reproduce a string quartet superbly well - it just does, not, compute ...
The vast majority have not heard what a Genesis will do.....2000W + 2000W 16Hz - 120Hz., then add your own amps for the mid/high panels.
This customer spent $200K so he could listen to Baroque quartet music....boring.
When given the chance I whipped out a couple of cds and let it rip...whole body experience
.The standard audiophile has no concept of what is possible in the home environment.
And those Lowthers are just plain junk.

Whizzer cone technology is right there with steam engines and valve computing - completely outdated. Plus, these speakers have too low Qms and too high Qes to be good for anything else than a high school science project.
