I would love to hear about your dad's inventions and see pictures of his decoder boxes. This topic deserves it's own thread. Some people here were starting to get upset that we were hijacking a thread about Virtualization for (Stereo) Headphones by talking about multi-driver (vintage quad) units!HELLO!!!THIS WAS MY DAD'S WORKS!!
This is so amazing to find this thread online, talking about my dad's inventions (The Fixler Effect, Quad-4 Stereo, Surround sound headphones (with the first actual physical surround isolated - which prevented that weird "in-head" nasty surround effect).
I still have these ORIGINAL WORKING ANALOG decoder boxes
If I can answer any questions about his inventions or any of that, I would love to! So cool!
Other than a magazine advertisement I have never seen an actual pair of "Fixler Effect" phones. Koss and JVC used the basic (or similar) idea in some of their phones but I bet that your Dad received no royalties from either of them!
I would consider your Dad to be one of the great Quad Gods!
