I only get woofer pumping with a handful of warped records in my collection/system. The low cut filter in my Luxman EQ-500 works wonderfully in these rare instances to virtually eliminate cone flap. I believe it starts gradually rolling down output under 50hz and attenuates -14dB at 6hz where the effects of warps are strongest.
TT rumble versus "oscillation": what's the difference?
Playing some LP's I've described forward and back movement of my mid/woofer drivers. No obvious noise emanates from the movement that can be visualized. I assumed that this was evidence of "rumble" but have been informed that it might instead be "oscillations".
So my question to you vinyl gurus: what is the difference between those two conditions? Is one worse than the other? Do both compromise performance of the speaker and the driving amplifier?
Thanks!
