Repairing old speakers.

post #1 of 4
Thread Starter 
I've got a pair of OLD cabinet speaker from a Fischer Studio Standard component set. It's about 25-30 years old. The components all work but I'm not going to use them as they are just stereo Analog L/R connections. I might have use for the Amp100w 2channel but It's the speakers I'm really thinking about.

The woofers are paper and have dry rotted in storage. I'm thinking of getting new 12 woofers and fixing them or taking them some place to get fixed. These are the specs written on the back of the speakers.

Model..................St-920
Power.................20-90 watts
Imp.....................8ohms
Freq....................45hz-30khz
Woofer...............12
Mid.......................5
Tweeter...............4 Metallic horn
DIM.....................H-28, W-16, D-12
Reset button
Mid and Treble Volume control (boost?) on speakers

Has anyone had any success restoring something this old. They are very well builtshould I pay for a professional to repair them or is this something I can do on my own. Any comments appreciated.

They have more of a sentimental value than anything else as they belonged to my granddadhe liked his music and he liked to share it.

This is a sealed acoustic suspension speaker, I presume. Just replace the 12" woofer with something like this: http://www.partsexpress.com/pe/showd...number=290-335

Measure the mounting hole of the mid and look through the paper cone mids for a replacement. Be sure to look on the back of the drivers to find impedance stamped on them somewhere. The mid or woofer may actually be 6 ohms instead of 8, even though the entire system is labeled 8 ohm nominal.

Thx for the link and the additional info...I went to a place here in NYC and the guy wanted to charge me $65 each for 12" woofers. I never thought about the mids...they look fine but are covered by a metal mesh so I have to remove it to really see.

Thanks again

I've used http://www.simplyspeakers.com/ in the past. They've refoamed some drivers for me and I've bought their kits. Good people to deal with.
