FS: ATC Setup with EC23 Active Crossover

Before I potentially part out this setup, I thought I would attempt to sell it as a complete set. I am located in Ottawa Canada, and would ideally like to sell within the eastern Ontario area. Shipping would be too difficult.

This is a loudspeaker that started off as the passive Proac Studio Tower, and slowly shifted towards an ATC SCM50. The original Proac Studio Tower had the ATC mid and woofer, and a lower level Scanspeak tweeter (now replaced with the Seas T25). After many years of research and sleuthing, I was able to put together the existing setup which includes the following:

  • ATC SM75-150 Mids
  • ATC SB75-234LC 9” Woofers
  • Seas T25-003 tweeters (these are the non-ferrofluid versions that ATC supposedly liked more than the T25-001 version)
  • SB Acoustics Satori WO24P-8 9” woofers (currently installed in the system)

So you get two sets of woofers to try - the original ATC or the new SB Acoustics Satori WO24P. The Satori provides lower bass, but does not have the power handling of the ATC.

The Proac Studio Tower boxes were modified with the following:
• Internal bracing added
• New Removable baffle to match ATC SCM50 layout
• Threaded inserts to fasten the baffle to the box
• Rear ported, but could be changed to front
• Speakon connectors used

Electronics: I was able to source a very rare ATC EC23 active crossover a few years ago. These were generally used in studios for the large SCM200 but use the same crossover points as the SCM50, 100, 150 etc.
- Currently set at 380Hz & 3.5kHz but can be changed through resister replacements
- PDF manuals and setup guides included
  • Comes with a plexiglass front (not pictured) which studios used to protect the values from getting changed by accident.
  • Adjustments include level, phase and has mute switches for each channel
  • Super quiet and works perfectly.

Let me know if there is any interest.

Price: $3200 CDN or $2400 US

And did you know that ATC no longer sells to the DIY market?
