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.

Cleeds, since when is a resonance point a "brick wall" situation. The resonance peaks then rolls off. If your woofers do not move at all visibly and you are playing vinyl either your woofers do not go down very low or your cartridge is too stiff for your tonearm and your bass is rolling off prematurely. I suppose you could also be listening at the volume of a mouse squeak. I would never use an analog filter. It would damage the bass too much but digital is a whole other world. I could survive without it but volumes with certain records would have to be limited and It might rob enough power to affect the room control function. There are no downsides to a digital filter up to 80 dB/oct. With a 3 dB down point at 18 Hz the effect is totally inaudible.
The problem Cleeds is that the source is vinyl, a medium that is imperfect at best. So, treating it at it's source means not playing records.

I'm the opposite opinion.   The digital filter would destroy my analog experience.   It would mean the introduction of analog conversions to digital and back.   If I need a filter, I much prefer a gentle analog filter to this level of processing.
