How to fix Technics SB-T20 Speakers?

Chellspecker · 10th September 2012, 06:35 AM

I have a pair of these speakers, and they've been great. I picked them up at a thrift store a number of years ago. The bass on one has become very distorted and I think I may run into the same problem as described here: Technics SB-T20

I have never repaired a speaker before, but I would like to try to repair them rather than just ditching them. They work fine otherwise. Any help would be much appreciated. Total DIY Audio noobie here. Thanks.

Hi,

Bayonet mounting is like a camera lens, usually rotate counterclockwise
to remove, used quite a bit in that period, its not common now at all.

Some points on the driver that would allow this are a clue to it being the case.

rgds, sreten.

apologies to the OP in the other post, don't know why I didn't reply.
