rusty cage sounds muddy still. put my fingers gently on the poly woofer cone and it cleaned up the sound.

thoughts?

Is that one that you refoamed? If so, did you use shims to make sure the voice coil stayed in perfect alignment?

Voice coil rubbing would sound like the situation you are describing.

yes, I refoamed. And no, didnt know I should do that. once all this dies down will take both in to make sure its done correctly.

midrange on that same cabinet has its center cone pushed in some. Think it can be suctioned out, otherwise will that effect any thing if it isnt?

Dustcover on the way. Just so happens the same cover fits model #s 1007 and 1008.....

now, having a speaker issue. With vinyl and bass heavy groups it sounds like the woofer is blown. Through headphones its fine.  switched speaker sides. other speaker is fine on either channel. that specific speaker with vinyl sounds blown on either channel. both in A or B positions......

Play a CD? perfect sound.

thoughts?

Contacts on your cartridge/tonearm, maybe?

I’m stuck with this bare bones setup on the second floor for now. (The Advent towers are just functioning as stands for the Audioengines until I can get my receivers serviced.)

I find myself feeling bummed out about your receivers. That sucks, man. 

At least you have something to get by with. I imagine the AEs are good but in a different league than your Advents?

Those Advents are actually from the maligned Jensen era, but they are probably my favorite speakers. Incredibly tight bass. I could listen to them all day. 

The tube preamp helps bring some warmth to the Audioengines.

The pushed in dust cover shouldn't make an audible difference. I've had good luck pulling them back out with duct tape. Just a small piece wrapped sticky side out around a couple fingers. Go slow and work in a circle. 

About the woofer, debris falling into the voice coil when you have it apart will cause distortion issues too. Might have to blow it out with canned air if you decide to go back in.

I've never heard a pair of Advents that I didn't like, regardless of era. You have a sweet setup.
