Ok, I've gotten to try some things.
1. As a temporary test to troubleshoot the polyswitch resistors, I wrapped some wire around their connections to essentially short them out. That way, if they are problematic, I can see what it sounds like "without" them.
...Conclusion, the speakers sound like normal now.
From what I read, it could take between 1 day to 1 month for the polyswitch resistors to return to their original crystalline structure. For me it may be worth waiting a month.
I will say that the speakers may be a little more dynamic bypassing the polyswitch resistors.
2. I tried a power conditioner with the new pair of Sonics 800X (Bryston 7b) power amplifiers. There is no pop on startup. There is still a crackle and pop on shutdown.
As I'm still in the test phase, I added a Adcom speaker selector switch so I could disconnect the speakers from the amplifiers during startup and shutdown.
Right now I am just using single TC9 drivers open air on light stands for these tests. That way if something bad happens, it's not to the line arrays.

I remember I had to add a soft-start to my amplifier, not specifically for pop noises but starting it up triggered my breaker switches 😀.
I got it off of ebay, you can see it in this picture on the right:

New project. I'm working on adding these JBL cinema speakers to the setup.
I also have two JBL 2445J compression drivers with horns that I plan to add to the system as well. That's longer term though. I'm out of channels of DSP as it is.
Before I add the 15" cabinets to my system, I want to refinish them in white.
Do any of you have experience painting over vinyl?

Someone had bought out all the speakers from a movie theater that went out of business. They were selling them out of a warehouse. It was a full day of driving to get them.
is "nv" for Nevada?
And if so, could you point me in the direction of your CNC guy? (I live in Nevada)
I had the same experience with the cheap aurasound drivers. The company is well known for their mid-priced stuff, and a couple of monster 18" subs, but their cheap drivers were all kinda "meh."
Basically, the Tymphany TC9 and TG9 are about as good as it gets at their price point, and to do better you'd probably have to spend 400% more. Scanspeak 10F is the obvious candidate, but 50 of them cost $6000 :O
Here's a quick update. I now have two JBL 2446 compression drivers handling the highs. The line arrays are handling the mids. The bass line arrays are handling the low mids and upper bass. The line of 15 inchers behind the couch are handling 55hz down. There is also an HSU and an Infinity sub as well.
I still have some unfinished projects: Plugging the ports on the 15's.
Making stands for the compression drivers.
Adding my other 15" sub.
Adding another amplifier or two to get more out of all the 15's.

So tell us, how does it sound? That's quite a bit of surface area you've got there to cover all the tones!
Could you try and describe how it knocks your socks off? 😀

It's just so effortless! The compression drivers add an airyness and subtle detail that I haven't had before ....I really want to make some stands to get those up at ear height.
Also, because the bass is so diffused around the room, you cant localize the bass. The bass just is there wrapping around you as if it's just the music.
The row of drivers behind the couch does shake my back from time to time.
