Help/IRS Beta Control woofer replacement

Need help in finding control woofer-any help would be greatly appreciated.
Regards, Glenn

I too am looking for the same to complete my IRS-III system and wonder if you've learned anything since your posting? I don't know how helpful this might be, but I own a beautiful set of original Beta's, so possibly we could determine the specifics of the accelerometer and placement for you to reproduce? I have been thinking of trying the same for my IRS III's, but would prefer to have some better qualified input from someone that knows this stuff.

Give Bill Legall at Millersound a call, (215) 412-7700.

As you can see, the entire IRS line is something he has up close and personal familiarity with.
