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.

I used to get a lot of woofer pumping when I had a suspended deck (Manticore Mantra) but not when I went for one with a bit more mass ( Townshend Rock 2). At the time of the Mantra I had a pretty basic Sansui amp (AU217) and mission 700s and with those the pumping didn’t seem to effect the sound.
