I dont care what quality of parts you put in this crossover it is an abomination in terms of complexity and total number of parts. Seems to be a very complex way to approach whatever problem Mr Thiel was attempting to solve. When I look at a crossover like this I simply scratch my head and wonder why.

This info on the caps below in italics is from the owner that stripped them, and "time alignment" parts info from Thiel. The two midrange units, for example, are electrically "moved backward," by the equivalents of ¾" and 3/8" respectively, to bring their acoustic centers into the correct alignment. It does *look* like there are 2 ELs at the bottom of the picAll coils apart from one are air-cored, and the capacitors are polypropylene and pure polystyrene types Cheers George |
@georgehifi Yes, I read all of your earlier post. I’m just saying it looks, LOOKS, like there are two ELs on that board. All the yellow caps are probably the custom-for-Thiel polystyrenes. On other models I’m more familiar with these were 1 uF bypasses (much of what I know comes from Tom Thiel). The larger black ones with red ends look like Solen polypropylenes. But there are two smaller black ones with a middle hump and rounded ends that are similar shape to ELs. For example (Link) |
But there are two smaller black ones with a middle hump and rounded ends that are similar shape to ELsPossible, but the guy that stripped those xovers and posted the pics says they are plastics, Those ones have "two little men" on them after I zoomed in on them, which I’ve never seen, and they seemed to have been bypased with poly’s If they are bi-polars electros then yes change them as they are only a couple of dollars each.
