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!
Joe

Another word for rumble filter is subsonic filter. I have a Technics 1200G and this problem was eliminated by activating the subsonic filter on my phono stage.

It is the nature of the vinyl format to have this rumble.

Not sure it helped in any way but I kept the subsonic filter off when breaking in my Tannoys.

I also ran my Salk speakers for 10 years with the subsonic filter off. Nothing bad ever happened. Woofers were always ’excited’ during the space between LP tracks.

For me, activating the filter didn’t seem to help/hurt the sonics in any real way.
