i recently brought a marshall1960ax and ive been playing it through a Randall rh150g3 on a schecter demon fr tuned to drop c
my problem is it seems it cant handle bass very well when at loud volume (sounds terrible and viabrates a bit)

will different speakers fix this ...any suggestion on speakers
or will a noisegate or eq work
what speakers are in the cabinet now? I've got a 1960A, myself, and the bass response is phenomenal.
