inline subsonic filter turntable vs clamping

#Inline subsonic filter turntable vs clamping drivers#

While there is definitely more driver movement than listening to CD at the same volume, it is not as excessive as some I have seen, and like I said, I do not hear any degradation in sound. So my question is, do I really NEED a rumble filter and/or to find a more appropriate cartridge for my setup? Or is this cone movement acceptable/okay to ignore if I do not hear it? At what point does it become dangerous for the speakers? I am posting a video of the movement, so you can judge for yourself. Looking at the vibration in the cones, it is definitely more noticeable than when listening to a digital source, however I do not hear any significant degradation in quality. Secondly, my TT is a Thorens TD160 (stock TP16 arm) and Denon DL-110 cartridge, which is a pretty common and widely used combination as I understand. My guess because the Harbeth's are not a bottom-heavy speaker and are less likely to reproduce lower frequencies associated with rumble. What is baffling is that I did not notice this with my previous speakers.

I have read that a subsonic/rumble filter would address this, which my preamp (AR SP-9 mkii) does not have. Doing a bit of research I have come to understand that this is most likely due to subsonic vibrations due to cartridge/tonearm compliance mismatch.

When I am playing vinyl I noticed the drivers (particularly the B200 unit) moving quite a bit more than with my previous speakers (Harbeth P3). I recently got a set of KEF 104ab speakers.
