Good morning speaker doc. I have a good sounding yamaha NS555 floor standing speakers. Last two years ago, one of the tweeters blown off. I have it repaired/rewound at AVX sa HP pero hindi na naibalik yung dati nyang tunog. Two months ago, na dead naman yung isa pang tweeter. I wonder why, hindi ko naman ginamit ng three weeks, after that dead na siya. Up to now, hindi ko pa napapagawa. Kaya ba natin eto irestore sa dati niyang sound quality?
