Solution for Whizzer Cone Rattle?

[tripathdude]

I built the Half Chang cabinets for my Pioneer B20. I modified the drivers with two coats of puzzle coat on the main cone and two coats of damar on the whizzer cone. I removed the dust cap and installed a phase plug. The speakers sound great except when I play bluegrass with alot of bass or techno music. Should I remove the whizzer cone? What would you suggest?

I just finished the shadow cabinet with Dayton 8" subs and the suzy chang cabinet with Pioneer A11. I will post a comparison between the half chang and the suzy chang with subwoofer cabinet soon. Thanks

Howdy tripathdude, did you try the 98 cent tweak yet?

(98 cent tweak info starts about halfway through the post)

I look forward to your comparisions of the Chang family!

Hey, back to this 98 cent whizzer tweak

I see DD's drawing (of the whizzer tweak), and am wondering if it is a non-glue reversible mod? Does one merely pressure fit the foam between the whizzer and cone and it works?

(Sorry if so many already know the answer--any comment greatly appreciated)

The reason for asking is one of my fe166's seems to make a buzz/rattle on high energy transients in the cello register. That whizzer really dances around at high spl's, and it looks suspicious.

Thanks in advance, dudes/dudettes...

Techno - OK. But bluegrass with a lot of bass? Must be some new grass I don't know about.


Or maybe you meant "Bass", like the fish.....
