Where to check/fix?

Hi all,
I have a pair of old Fidek floor standing speakers. Recently I realize the right channel midrange are not working. Just the tweeters are working. There is nothing wrong with my amp so I am wondering whether could you guys advise where I can bring it for it to be checked or probably being fixed?

might be easier to help you if you could let us know where exactly in Malaysia you are located friend. Perhaps this is one of the reasons to fill out 'location' when you register here, a bit more seriously. 

Nevertheless, if you could let us know where you are (pj? kl? penang?) i'm sure our friends here will help you. 

Right now all i can say is take it to an electronic or hifi shop. 

Sorry about that. I have updated my profile and by the way, i am from Petaling Jaya, Selangor. 
Any shop that is around this area which i can go to?

3 persons can help you.

2)Mr.Oh call him at 012-2060888
3)Or Edmund Jude at 012-2174777. Edmund is in Kelana Jaya area. 

All excellent and very professional.
