Your description suggests that there is a resonance problem between the tonearm and the new cartridge. If the resonance point of the cartridge/tonearm combination, which is a function of the tonearm's mass and the cartridge's compliance, is too high (typically in the 11-12 Hz range), then the tonearm can begin vibrating (similar to oscillation) so severely that the tonearm / cartridge can actually bounce clear of the groove. If you have a test LP with a resonance mode band, you should use it to check if your tonearm / cartridge combo to determine if it has a pronounced resonanance mode. If so, you will probably have to get a different cartridge (one with either higher or lower compliance) that works with your tonearm.
HELP Please what`s going on with this CARTRIDGE
Help; I installed a new cartridge.when playing an album I`ve noticed the woofer vibrating and shaking.When I raise the volume they really shake as if they were going to jump out the cabinet.Is there some type of sub-sonic frequency here. I have checked all of the cartridge setups and alignments they check out ok.Is this some type of high-frequency modulation.I cannot figure this one out.Thank YOU for your input.I need HELP.
