Did you get your JBL’s yet?
I imagine they will sound a lot like my AR-2ax, and I see they have controls for the volume of the mids and tweeters relative to the woofer.
In my case, 1 pair, I was able to clean the existing controls, the other pair, I bought new. They are a big part of their success.
I learned here that L -Pads are different than and better than Simple Pots.
