Turntable Causes Speaker Cones To Excessively Move Rapidly

I’m just going to add a recent experience, and my amateur suppositions:

it involved a slight warp, combined with very light tracking, combined with mismatching the high compliance cartridge with an arm best for medium compliance cartridges.

I successfully used my Shure V15VxMR cartridge, tracking at 1.0 gm on an SME 3009 II arm. (on a TD124 TT). Wonderful, trouble free for a few years.

I broke the beryllium microwall tube cantilever. Saved the body.

Recently a NOS Stylus came up and I bought it, installed it, mounted it in my JVC Victor UA-7082 Arm. Some Shure’s have the damped brush to help with dust/static/ and warps. Add 0.5 gm if you use it.

At 1.0gm, it mis-tracked. Later, I increased it to 1.17 gm and it played well:

Except, warps.

I think light tracking, combined with a heavier arm, combined with a warp: once you get that heavier arm moving up, with such light tracking force, it raised the stylus enough to allow/cause mistracking..

IOW, you get it balanced, add 1.0 gm TF, it’s not heavy sitting still, until you get it moving up, then it’s greater weight is working against you for a while

I haven’t really played other LP’s with it. I went back to my AT160ML which plays trouble free on that arm at 1.25 gm

OP

Please explain what VTA at 0.5 means?

Perhaps tell us how you set/aligned the overhang and two null points.

IOW, is your cartridge aligned properly.

remember, anti-skate to zero when setting tracking force, then add just a little anti-skate

Technics 1200G Owners:

Using the dials on the Tonearm, how accurate are the tonearm's dials to reality?

i.e. I found my SME 3009 II, both the tracking force and anti-skate were very accurate, while most other arms, the settings on the dials were inaccurate.

I had the same problem. My turntable was a Clearaudio Performance DC, Charisma MM cart, Pass Labs phono amp, T+A 3100HV integrated amp and Wilson Audio Alexia speakers. The culprit was the Pass Labs phono amp. My Manley Chinook phono stage did not do this. I removed the Pass Labs amp and used the phono stage in the T+A. Not only did it eliminate the woofer throbbing, it sounded great.
