Isolation cones.

I'm looking for small ( short about 1/4" to 1/3" ) isolation cones to place under speakers but no luck anywhere I look. Anyone has info. please help. Thank you.
Try these:

Less than Audiopoints and just as effective.
Single piece cones and or points are more effective and sound better than the multi element points described above.You have much superior coupling and energy transfer with a single surface/element device.Tom
They do not sound any better and the shamless self promotion of some posters is inexcusable.
There is no audible difference between the Audiopoints and Adona products. Used both on a variety of components.
