Mystery with woofers. Help!

I am the proud second owner of three-way, sealed design, YG Hailey 1.2’s, and have enjoyed them immensely. They make plenty of articulate bass, provided that the recording is up to snuff. The bass is supplemented by one Rythmik sub, crossing over at 50hz.

Over time, I have noticed almost zero excursion/movement from the woofers so last night I decided to get down and put my ear/hand up to the woofers and it seems like NOTHING is coming out of them, even at pretty high playback levels. Again, my curiosity was not piqued by a lack of bass during listening, but rather, the lack of any visible movement from the woofers. Am I missing something? Fwiw, I am feeding the YG’s with Pass X260.8 monos, connected to the upper speaker terminals. Thoughts?

I'd find some wire in my garage and make some temporary jumpers and be reporting back how the bass sounds by now.

Fair play for owning up.

I feel like an arse

This reminds me of the time I was at a friends house. He has small floorstanders and the woofers had ALOT of excursion. My Avior ii speakers don’t have very much excursion but give tremendous bass. I was curious about the difference so I asked Duke at audiokinesis and he said a woofer that moves a lot is trying to do too much and the sound quality will suffer. He did say that it’s not a design flaw when the woofer has that much movement though. Happy new year to all

Remember that jumpers are part of the speaker cable line and get good ones.  I replaced standard stamped metal jumpers with cyro treated strand jumpers and it made a big difference.

Passive cones makes the most sense.
