You will be delighted to know my Duelund CAST Sn-Cu 100v caps arrived. I've had them clipped into my starter network for a few weeks now. They are awesome. I need 4 more of these in 3uF so I can combine them to work between 5 different speakers - on the tweeter network.
It's a lot of money for caps, but it's really nice when you spend money on something and it's worth it.
So what is below are some version of what are in that speaker, likely on the tweeter. With it having MTM mids, there is probably a 100uF+ value on the mids, and BIG values on the woofers. Those are the values necessary for those spots, and in CAST would be HUGE money. So, I bet that's what the Mundorf are for.
