Polk audio tweeter “spitty “

D3, that AP is wayyyy more capable than I am, I have barely scratched its capability and don't understand a lot of it. But what I do understand and use its pretty damn awesome..
 
Lee and 3D, please post your test gear in the thread for vintage meters. That way any guys wanting to get into building, testing and troubleshooting will have a spot to look at various equipment they might want to start accumulating.
I agree with 3D that learning on analog stuff builds a better foundation than jumping straight into expensive digital gear. Obviously there are some exceptions but in general learn to use a wrench before you buy an air ratchet.
 
Well, if I swap cables and the problem follows the cable, and is not resident in the speaker, we then know it's not the speaker.

If it remains in the same speaker, regardless of connection to it, the problem is in the speaker.

Then we could dissect the crossover, and rebuild them both with fresh caps. Probably not a horrible idea anyway, but these are not that old, so not my first thought.

Do these tweeters even HAVE ferrofluid in them? That thought occurred to me today...

I have been ignoring this problem continuously since I noticed it.
It's probably your cable Jim :-)

Prop the speaker cables off the floor with chopsticks and that usually mellows them out. Perry usually has some advice on this...

Can't talk now.... Still giggling over the last "Slurp and Burp"

The bottom line is that I am definitely headed in the direction of yourself , Grapplesaw, & Gepetto...but I gotta crawl B4 I walk B4 I run with the big dogs. :0)
 
The tweeter may be swapped easily. Tweeter terminals are plug in connectors. Crossover caps cannot cause "spitting" , only treble attenuation (horns are the exception). Ferrofluid gets thick with time causing treble attenuation, but not spitting, however it would be good to know if the spitting goes away when the volume is reduced 10%.
The woofer in this Polk also separates the rubber from the cone, so try to gently lift the surround where it is glued to the cone. Any loose rubber will rattle at certain frequencies.
 
I've had no time to look at this again. I will do this weekend and try to get more intel on this problem.

It's usually 10:30-11PM that I finally have time to do.. something. Trying to spin records 'til midnight or so but I'm pretty tired by then. (Can't make any noise with the little man sleeping)
