Thanks everyone, before the salesman send in the noise pair to Tara, he took off the loose rca from both cables, he said he just try to see what's wrong with it, then Tara said they have no way to test it now, so they won't pay for my tweeters, the salesman told me he can give me $500 credit if I buy the $2200 ISM The One, 25% off, but not pay my tweeters if I don't buy anything, I think SF Stereo just be in bed with Tara.
