In the Thread: How to USE “Resonating Oops” in loudspeakers
Post Subject: The Russian take on the “Resonance Oops”Posted by Romy the Cat on: 3/10/2008

There is a speaker maker in Russia, Moscow – Alexander Kniysev who just introduced his own take on “Resonance Oops”. What he does is not my cap of tea and I see a number of issues with his design that I would object but it is not my speaker. Nevertheless what Alexander does with this implementation and how he thinks about it I feel is very worthy attention. Watch out the lazy Feastrex people – this is what you should be doing. Here are some free translations of the comments Alexander made in responses to my questions.

“Those panels are rather an outcome of my intuition about sound then a design based upon formal acoustic principles.”

“The system implies harmonic integrations between driver and panel “

“In my view the panel influences sound much more then driver, I generally consider that if an audio acoustic system speaks only via a driver then it is a mistaken acoustic system.”


Certainly Mr. Kniysev’s way to implement the “Resonance Oops” and my ways are very different but it is what it is and I think Alexander’s attempt is educational.  The Alexander speaker has 96dB sensitivity and employs  in-house made dual-concentric alnico driver with both paper cones and leather suspension.
