Woofer sucking in and out

I have a problem with my analogue set up that once it starts play, the woofers of my speaker will move in and out like crazy, unrelated to the music! It relates with volume as when the volume is low, the woofers will not move as much. May it has to do with oscillation between cartridge and arm but my set up is new. The turntable is Acoustic Solid-Transparent and rega301 arm with cardas wiring and weight mods, Herron VTSP 3A pre and VTPH phono. I wonder if placement has anything to do with it or power connection.
I hope someone who has the same problem before can give me some hints.
Thanks.

Rodman, Thanks for the info. Very useful! Ah.. Has anyone used those heated device to flatten a wrapped disc?

I have moved my TT to another spot at the back with some success. The movement is not as big as before. I call the manufacture and he said some movement is OK as long as it does not bottom out the woofers. I also find the movement heavier at the outer rim and less when the arm reaches the middle of the LP. Does that means it is related to the arm's set up?

True, the degree varies with different records. As long as it is not causing damage to the speakers, I will be able to live with it!

It made sense as I have only moved the set up to the location next to one speaker on the side wall lately. It was between the speakers before. I thought equipment on the side is better than in the middle. I will try to move them back. I was thinking the tubes has gone bad or something? Thanks for the help and I will get back when I have some progress.

I can rule out DC leak as there is no problem with CD playing. Thanks.

Cool responds. I am only using Thorens weight at the middle. Most of my LPs are used so the arm is moving up and down some times! I will have a look at rings and weights than. Thanks.
