Full Review of ATC SM75-150S Midrange Driver

Looks like the ATCs are too hard to get. I'll keep my eyes open. But ordered the 18 6ND430s I'm set up for a quick implementation and they crossover well to the SB 29s.

The Purifi PTT4.0W04-01A look great for a book shelf system.

I prefer the ATC. The best way to describe the difference is the Volt sounds slightly thin and more analytical compared to the ATC.

[Drummer]

Craig, what do you find the sound differences to be? I've heard the ATC in a ProAc speaker with Scan woofs and tweet and thought it sounded fantastic. Buttery smooth. I've never gotten to even see a Volt in person. Glenn.

One more thing. The Volt and ATC drivers sound very different.

[Paul Ebert]

It may be that the Purifi PTT4.0W04-01A gives both the ATC and the Volt a run for their money performance-wise and for about half the cost (or less). Time will tell.

The EighteenSound 6ND430-8 looks like an easy to use device that may be a distant 2nd but good match for my taste and SB29RDNC at 2.5-3Khz. The $1200 savings can go to new carpet and some diffusers.

I tend to like devices that have low THD but with the 3rd order lower than 2nd. I guess I'm funny that way. LOL

Volt not ATC

I was referring to the Volt, not the ATC, but it could be back I guess....

They are back on their website, $ 750.00 each.

TMK, it's only available in the northern neighboring country, and from the same place as that makes their own caps in France.

It shouldn't be available there either. ATC changed their policy a while back and they will not authorize the sale of the mid to individuals anymore unless it is a trade-in on a damaged unit.

I found the Voice Coil review and distortion is very low but I've yet to find it in the US, I'll keep looking.

hello Jeff and others!

How does this midrange still rate today, is there something much better, or any better? Is it still available to DIYers, where? I
d like to keep the crossover around 400hz.

I'm going threw some life decisions and looking to finalize my main system. Cost isn't much of a concern. I'm selling down a bunch of junk that'll easily cover an expensive midrange. The AE TD15S will stay of course!!

Thanks!!

Check this out, Scott. The ATC is not available for diy, but the Volt 752 3" dome is. The open source monkey box uses the Volt, and the thread contains tons of measurements . Glenn.
