From the measurements in post #1 the port resonances are directly below this bump. Any clues to distinguish if it is port or woofer resonance contributing to the bump in measured response ?Indeed, I'd blame the resonances as ~ 900 Hz and 1.4 kHz

It's not present in the tweeter. It rolls off considerably above that.I see it in the woofer, port, and tweeter...
I think that's just sound bleeding in to the one from the other. Remember, that that these measurements are taken with the mic close to one driver - but not excluding the other drivers and ports.I see it in the woofer, port, and tweeter...
Today, I am giving the Stage A130 another chance. I recently replaced my Denon AVR with a 2020 model vs the old Denon 2015. The AVR speaker calibration, has an improvement over the 2015 model. So, we will see, over time, if I stay with the JBL or not. Maybe the more neutral sound will be more liking to my ears, on this second go around.

new fill would make some improvement in cabinet resonance??because it's a cabinet resonance, neither of these 3.
I plugged the port and it didn't change the response there at all.
when Amir measures the nearfield response he cannot isolate the cabinet.

did you take measurement of how much reduced low end extension was after plugging the port. It may help crossover point if sub is added.I plugged the port and it didn't change the response there at all.

Well, I am keeping my JBL Stage A130 mains. The Klipsch R 51M mains, will find another home, if I can sell them. Having the stock Stage A130's, are great for DD movies and MP3 music. I just needed more comparison time and the JBL's are more neutral, which I now appreciate.
I don't think I have measurements right now but it was significant, I cross my A130 with my subwoofers at 110Hz anyway for minimal distortion. Above 100Hz the A130 are clean as a whistle for their size and cost.
I'm surprised you guys aren't liking 80 Hz. It must be your rooms forcing a higher XO?
