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.

No one has mentioned the fact that reflex loaded speakers go nuts when driven below their tuned cutoff frequency. Does the OP have vented or sealed? He doesn’t say and our experts don’t ask. But the observation that this phenomenon is limited to new releases is suggestive that  we are dealing with a software anomaly and not a playback system misbehavior.
