Speaker Surround Repair - Sony APM-33 - square drivers
Posted 20 November 2012 - 05:55 PM
I was wondering if anyone has had experience with replacing surrounds on the square bass drivers of a pair of Sony APM-33 loudspeakers? They are around 6-8" across the flat sides from memory.
I spotted a pair for sale and was thinking about buying them and repairing them if possible. I have read on the internet how to manufacture new ones out of chamois, but would appreciate any other suggestions.
Comments on the speakers' sound (or similar model) also welcome!

People have had good results with the chamois method, it's a lot of work though.
The advent of 3D printing, especially in materials like rubber and foam, is starting to make our lives easier with this kind of thing.

I'm still wondering whether to just replace the bass drivers with others while still keeping the cabinets original...I have a few different 6" drivers to play with. Decisions decisions...

But if you decide to get rid of the bass drivers don't throw them out! Send them to me, I'll put them aside for spares as I have a pair of them too.
Personally, I'd order the surrounds from the Russian and re-do them. If he asks alot for postage maybe I could buy a pair too and we could split the cost.

I am new at this forum, but yes, I have experience how to repair these Sony APM-33W woofers.
If you have any questions let me know.
