Why do my bass drivers shake violently listening to vinyl


Hello Gon'ers,

Help needed. I took the grills off my new Vandersteen Treo CT's recently and noticed that when listening to vinyl, the bass drivers shake violently, meaning the amount and frequency in which they travel in and out. Then I played the same pieces of music from Tidal and they were relatively calm.

Is this some kind of feedback loop causing this? Has this happened to anyone else?

Thanks!

Different signal from each. Vinyl putting out more bass than digital. The question is how does it sound? Is it distorted? If so, then you may have a problem. 
It sounds incredible! I'm just concerned that I may be doing damage to my speakers. 
You likely have a mismatch between cartridge compliance and cartridge/arm mass.  Do a search.
