Carver C-9 sonic hologram generator will do the same thing if you can't find the cable. It cancells interaural crosstalk. Try to get the cables. BTW speaker placement is very important. It's not for everyone, but I was addicted to it for years. Good luck.
Polk SDA Speaker info needed...
I've got some older Polk SDA 1A dimensional array speakers and people are telling me that the sound is much better when you use the cable that connects the two speakers together. Can anyone varify this and also tell me how I might hook mine up just for a listen without having the polk cable? Thanks..
