He never replied

The thing is that I own ProAc E.B.S. cabinets (internally treated with bitumen and reinforced) I have upgraded with some Morel Supreme 130 tweeters, ATC SM75-150S mids (they are the problem to go ahead in a passive mode) and original ATC SB75-234 woofers. I also own the original E.B.S. passive crossovers, and I would like to know if they are about to work properly making some changes or I should go for another set of crossovers. Any info or recommendation?

Thanks in advance!

Regards,
Jgtx.

I think ATC use LR4 filters throughout. I also think I read somewhere that for their active models they use 16 Ohm version drivers, these not being offered for OEM or retail sale.

The 16 ohm mid is available retail but the "Super" version is harder to get.
Ordering from ATC directly is the best bet to get the 150S...but it is pricey.

Tried it. Didn't work. They keep the S version for their own speakers now.
