JBL Xtreme 1 vs 2 Bass Excursion

Is there a difference between those two? You tell me in the comments! Here is the setup. I am playing via my zoom audio recorder, split the signal with a 3.5mm Splitter 1M/2F Adapter, to both Xtreme and Xtreme2 into the AUX in ports. Both Xtreme are set to full volume, and in AC-mode, and i play the zoom at output level 100. My trusty Sony is recording this in 4k, and i am using the Sound Professionals in-ear binaural microphones. The sound doesn&matter so much, because they are both playing at the same time the same thing. At the end i have a few bonus seconds in slow motion. It looks like the signal processing in the Xtreme2 is a little slower than in the Xtreme1? Do i see that right? Or is it that the resonator has more mass in the Xtreme2? One more thing, in the middle of all of this is my new sound level meter. Did i see 111dBA at one point? WOW, that is loud! Have fun watching!
