Why the woofer moves badly when playing certain LPs


Hello. First greeting.
My turntable is Pro-Ject The classic, Phono is Lejonklou Gaio2.4 and Cartridge is AT150sa.

However, I am having problems with my woofer moving badly when playing certain LPs.
Generally, this is not the case with the older, dusty LPs of the 80's, but rather with the record just new released LPs.

I want to get help from someone who knows why this is happening.
Sorry for my broken English.
Thank you very much.

Years ago I had the same problem . It was an arm and cartridge mismatch. You need to know the mass of that tonearm and the cartridge compliance. If you do the calculations this chart will show the resonance frequency of that combination!
