Guess How Big My Speakers Are

If you read any of my threads on here or looked at my virtual system you probably already know the answer to this question, but for those who have not, try this as a thought exercise. Given this plot alone how big a speaker do you think this is?

Frequency response plot showint extension to 20 Hz

 

Hints:

  • 2’ from sides, 1.5’ from rear
  • Ported
  • Not horns
  • No EQ applied. This is the natural in room response using short sine sweeps.
  • For a living room this is a well treated room with GIK soffit traps, bass traps and diffusion panels strategically placed.

I’ll reveal my answer if we get 5 guesses or more. :)

I imagine the graph would look very different at an 80-85dB level.

@onhwy61  Compression is probably the least measured feature of speakers.  Only SoundStage regularly measured it, and I expect these speakers will have some of that.  I'll try taking new plots.

I can tell you one thing though, the Mundorf AMT's I use for the tweets DO NOT COMPRESS.  They have amazing power handling and incredibly low distortion.  The limits of excursion in the mid-woofers though will probably be a factor.

What does the curve look like at the listening position with the room acoustics taken into account?

The measurements you see are from my couch! :)  I use OmniMic, which will automatically blend in gated high frequency with ungated low frequency.
