Re: Technics SB-7000A

I am new so I am trying to learn this website. I have a pair of Technics SB-7000A loudspeakers I purchased new. One of the woofers is bad. Is there a source for replacement or service that can make a repair?

Anyone's assistance will be much appreciated.

And what precisely is wrong with him?

Re: Technics SB-7000A

What is the problem with your woofer? Because sometimes there is a dust between the speaker's coil and the magnet and he began to scratch.If so - turn speaker horizontally with the speakers down and let it run for awhile of average power. Many times this helps - it just cleans itself.
