Not the greatest idea to be adding weight to the cone...

ya we did a home test kit for the thiele small parameters and now the efficency is killed, the Fs was raised 13Hz, and transient responce was multiplied by a factor of 5

^Why do you say that?

"ya we did a home test kit for the thiele small parameters and now the efficency is killed, the Fs was raised 13Hz, and transient responce was multiplied by a factor of 5"

^I'm lost...how did you manage whatever the heck you are trying talking about?

What don't you get donniedude? Adding weight to the cone will change the t/s parameters and causes more driver sag. Even the slightest weight can throw off the t/s specs to some degree.

Something as light as a dust cap won't make an audible difference. Even on paper it really isn't going to change much at all.

And Jordan I just saw your other thread, makes sense now lol.

:-)

people add mass all the time to PR.... not the same thing, I know... but whats wrong with customizing your parameters? I want a lower Fs, and I'm willing to trade a touch of efficiency for it... but i dont know enough about that to do anything like that...and I DIDN'T

I added a tiny amount of mass, that MAY be detectable by KLIPPEL, but I bet you it is less than the production tolerances! AND, I bet the second custom coil, the added glue to hold the coil to the other layers, the extra set of tinsel leads, the extra anti-tinsel slap pad, and the glue to hold it is far less than the little bit of paint I added.


I made all that up about the measuring, as it almost sounds like everyone is making up just how much the TS params may have shifted from a few coats of paint ;)
