Just ask Billy at ATC he will tell you.

You mean, asking directly to the ATC website information email?

moray james 1st May 2010 02:14 PM

Yes.

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.

The original Xover points are 380 Hz and 3.5 Khz, but i dont know filter type or slope!

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.

I got a set of 150S placed on my closet.
