Demonstration Room

Where methods are tested before client work.

The CQS Demonstration Room is a measured, documented Dolby Atmos and DTS:X home cinema in Metro Atlanta.

What happens here

  • Speaker and subwoofer placement approaches are tried and measured.
  • Subwoofer integration is worked out with measurement, not guesswork.
  • Dirac Live calibration and REW measurement techniques are exercised end to end.
  • Every change is recorded, so results can be repeated and checked.

What we use

  • REW measurement software
  • Calibrated measurement microphones
  • Multi-Sub Optimizer (MSO)
  • Dirac Live
  • miniDSP processing

Why it matters to you

You get methods that have been practiced on a room we know well, with the same documentation approach we bring to yours: measure, optimize, document, repeat.
