ATC clone

I'm currently building a copy of a SCM100, I've got the HF and mid domes sorted, but I can't find any ATC 12" studio or hifi drivers, only the PA ones? I don't suppose anyone has a pair they're willing to sell?

That's very interesting for sure, can you share info, filters schematics, cabinet plans and such ?
It would certainly help the community and would encourage helping you in return
I am sure quite a lot of ppl here could be interested in such a project

Prototype un veneered cabinet. The front baffle screws on to the cabinet.

Port tube won't be that long! It's just resting there so it doesn't get knocked over.

Maybe these datasheets can help you find something equivalent... I think it would be the SB75-314, but these are for the original SCM-100, not the newer SL drivers.

I thought that ATC didn't sell any drivers anymore, but here is a shop with spare drivers in a catalogue. Maybe you could have some luck, but I suspect they'd want a Serial Number of the original to buy spare parts.

I've tried to buy them before from ATC, you're right, they want a serial number.

There´s a German company called aos-lautsprecher which offer DIY kits of ATC-alike speakers. Maybe you can get some inspiration there from their choices: https://www.aos-lautsprecher.de/lautsprecherkits/monitor/cm38/

I can only recommend them... A big step over my KH O300 or amphion one15. Hypex plate amps are great for DIY and the Volt Chassis are for example build in PMC monitors. Best Studio Investment...

Amazing ! Thanks a lot

Volt speakers definitely are a thing. A few years ago I heard a studio monitor developed at the university of Aachen (RWTH) using a 12" Volt driver. That was one of the most impressive set of speakers ever.

Obviously the Volts are great drivers, but I guess the question is whether they’ll reach as low as the original/play well with the port. I guess that any part deviation will mean potential changes to the port and crossover anyway.

Some similar specs to the original non-SL (albeit more efficient, higher XMax + power) from the Scanspeak Revelator:

The ATC50 ist not meant as ported loudspeaker. Its only for Ventilation at very high Levels. I never saw an original atcs inner life but i gues Theres a lot of damping Material inside.
The benefit of These hypex (253) amps are the digital Control of xover and plate amp gain to customize the system in your room. It does have an measuring function too.

Right, but the OP wants to make a copy of the SCM100, not the SCM50, this the 12” woofer and port (and why I suggested the Scanspeak rather than the Volt driver).
