The images have been removed by the host, so I've uploaded the xover schematic again here. (7 years later! How time flys)\n\n[URL=http://s608.photobucket.com/user/tenson_uk/media/ATC-20-Tweeter-Replace.jpg.html][IMG]http://i608.photobucket.com/albums/tt169/tenson_uk/ATC-20-Tweeter-Replace.jpg[/IMG][/URL]\n\nPlease bare in mind that this was simulated using the D27TG-35-06 as a reference instead of the original 27TG-46-06 becasue there was no data for that. It is said to be a drop in replacement. I then adjusted the crossover parts until the Scan-Speak 9800 matched as close as possible without massive changes to the crossover.
