My T-5000s has two pieces of foam per cabinet

What are the length and gauge of your speaker wires? Your avr-x3100w is rated at 105wpc into 8 ohms, 8 ohms should be the reference point to measure all amps. I have been running my avr-x3200w since ~2015 driving klf-30s & klf-c7 + various surround speakers with out a hitch. I does get warm but no more than the rest of my gear. Did you by chance have your avr in a closed-in environment like a cabinet? Or say having less than ~3“ of open air space above the unit? Emotiva suggested I have 12” of open air space min above my xpa-1s – granted we are talking about a lot of power but I think you got the idea. Would like to hear how you like your Crown amp.

I should point out that another member here found the screen under/behind the dust cover had some how got loose and it would buzz from time to time.

I recently went through the same ordeal with a klf-30 woofer. I had found the dust cap was loose & the plastic ring was also causing a buzz. It turned out two of the four woofer mounting screw holes were 'soft'. So it appeared they did not hold the plastic woofer ring down tight enough. So all drivers were removes on both speakers and used wood glue and toothpicks to “rebuild” all screw holes. And in my case that was the end of the problem. Note: I had reglued the cabs seams ~two years before.
