My speaker cones are moving excessively at low frequencies
Interconnect cables damaged
Make sure that the integrity of your interconnect cables is sound and they are firmly connected to your turntable and the SXV1.
SXV1 is close to external interference
Check the proximity of your SXV1 to any possible source of EMI and/or RF interference, for example computers, televisions, amplifiers, speakers, etc. Ideally the SXV1 should be placed as close as possible to your turntable.
Earth loop in system
If your preamplifier and/or amplifier have an earth/ground lift switch, toggle it and check which setting sounds better. The signal ground of the SXV1 is isolated from earth by default, this means that there needs to be a connection to earth elsewhere in your system to alleviate hum.
Tone arm set up incorrectly
Check that your tone arm is set up correctly and it is properly weighted and balanced.
Turntable susceptible to vibration
Make sure that your turntable is solidly mounted on a surface that not prone to vibration.
