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.

Speakers are Canton Ergo620
As far as I know, I don’t think there’s any problem with cable connections, the attachment of cartridges, or parallel adjustment. Because there are LPs that are very normal and have great sound like the link below.

At 0.49 I can see a large gap under the record at the edge. Approximately 1-1.5" of the outside of the record is not touching the platter. The record is warped. That is likely instigating your woofer excursion. If you have a resonance issue in addition as described by atmasphere, above, that will make it worse.

It sure looks to me like a stellar example of pickup arm/phono cartridge mismatch.

Use of a Subsonic filter or a preamp with one built in is almost a MUST when playing LPs. Subsonic filters were created specifically to remove that low end rumble and they work well. Just my two cents worth.
