speaker driver makes a thud (right one) when amp power kicks in ???
hi , just started to notice a significant thud when my amp powers up ( mainly right speaker ) basically its the bass driver moving outwards !! . i have not noticed it before , the amp used to just click quietly when ready .
is this a sign of age , wear & tear etc ?? i have checked polarity & left right scenario all seems ok !! .
there does not seem to be any deteriation in sound quality when playing either .
i am currently using a nad cd (c521i ) & amp (c320bee) combo with acoustic energy speakers , silver anniversary single run speaker cable & qed one interconnects . (basically the five star budget setup from a few years ago )
if anyone has any ideas please let me know
best regards , rob .
