Looking for Teknasonic Vibration Absorber


I am looking for a pair of the Teknasonic Vibration Absorber Model C-10. It’s that plastic gizmo (from the eighties or nineties?) that sticks onto the back of a speaker to reduce cabinet resonance. I’ve scoured eBay and other sources. Does anyone have any leads for me?

Thank you everyone for your input - I really appreciate it.  Yeah, it’s a great product.

I recently put a set on my NEAR 15M’s and have been amazed by the improvement that they’ve made. They were great speakers before, but now I feel like I have really arrived – I am not really looking for anything else.  With the addition of the Teksonics, the sound is now extremely satisfying for me.  

In fact, the designer of the NEAR 15M was so impressed with the overall improvements that the Teksonics made for that particular speaker that he began to install one on the inside of the cabinet as a regular production feature and labelled it version II of that model.  

I actually have two pairs of the NEAR 15M’s, and my friend has a pair, so I am looking to grab two more sets of those Teksonics if I can. So, if any of you have any more leads for me about how to find some,  please let me know.  Again, I really appreciate it.
Has anyone tried the Marigo VT31 discs? Two of these discs have been on the back sides of each of my wooden speaker cabinets for some months now to damp resonance. They have had a very nice effect on my Nola Metro Grand 2s. I wonder whether anyone would consider the Tekna Sonics better still?
I used them on the back of my pair of Monitor Audio Studio 6s to great effect!
Thanks for bringing this product up again. I happen to have both the C-10 and the C12’s. I just put both of these on the base of my new Focal Sopra speakers, and sure enough it tightened up the soundstage.
Sorry but there not for sale now. Too bad someone else hasn’t taken over the design though...
