Whizzer cone removal

You might first try the non-damaging/easily reversible 98 cents open cell foam tweak.

Cut a thin strip of open cell foam and circle it around the outside bottom of the whizzer cone.

Readily available open cell foam is the Gray foam stripping often supplied with window mount air conditioners.

Or, just order open cell foam online.

Try difference sizes/amounts and vary the placement.

I use vintage Elac S517 drivers with whizzer cones (not listed with my setup) and have used various other vintage whizzer'd units from England and Japan.

Thanks everyone. 

@dekay I'm not sure exactly what you mean. If you can and wouldnt mind can you send me a pic?

@bache thanks for your input and experience regarding the whizzer situation. 

I get that I might be screwing the pooch here if I move forward with this. Why can't I leave well enough alone. I'm getting pretty great sound as it is. Curiosity killed the cat, or does fortune favor the bold, to be continued. . .  : )

My Hornings circumcised the Lowther drivers they used, removing the whizzer cone, and implementing a cone tweeter.  You may want to contact Tommy Horning for advice on doing so

Here's a pic of round foam dots used (I wrapped a strip of open cell foam around the back of the whizzer instead).

I first read about it @ Lowther America or DIY Audio.

Addendum...

As the "edit" function seems to be MIA...

Best not to "chop" the Decware drivers as they seem to be one-offs/custom-built and you can't go back.
