Message: Steve,
Thanks for the great advice and wonderful products,
each and every time.
Name: SJ
Message: It will be appreciated to explain how to install tube damping.

Herbie's reply: Damping instruments are placed on the tube simply by sliding them down from the top of the tube.

Message: Are there any white papers or essays on system isolation methods, etc. or is it best just to search on the forum for specifics? I have detuned car seats to isolate them from auto body resonant frequencies-any ideas what frequencies need to be avoided in an equipment rack? Is it better to stay stiff and create higher resonances that are easier to damp, or to stay compliant, assuming only frequencies too low to hear will get through? Dave

Webmaster's reply: There's a good intro to this subject at Herbie's forum here: "coupling vs. isolation" and lots of other topics.

Higher resonances are not easy to damp, especially micro-vibrations that cause a lot of problems with audio. Assuming only frequencies too low to hear will get through a compliant system is an unrealistic assumption. Different frequencies affect audio in different ways, with virtually the entire vibrational spectrum having potential to affect stereo performance. For an equipment rack, a combination of stiff and compliant is usually best, stiff for rigidity and control, compliant for decoupling and isolating the components and the rack itself. Choice of materials is most important, not just whether they are stiff or compliant.
