See Mr. Bruzzese's manufacturer's reply to the new Element Fire review. The elevated on-axis treble response in that graph should flatten out to the sides.

It would be nice to see a follow-up to the new review, with in-room measurements FROM the listening position and the speakers set up as recommended by Totem.

The elevated treble will not flatten out measurements do not lie however speaker designers and manufacturers lie every day.

Should also note that the LF blump may be an artifact of JA's nearfield measurement technique, and not actually that pronounced in a real acoustic space.

  Look at the speaker's impedance graph you will see the first impedance spike is smaller than the second spike this is because the cabinet is too small of volume along with a port that is too small.
  
  It is not an artifact from John's measurements. And Johns measurement Techniques are industry standard. And rooms really only effect from 200 HZ down. some will say 300 HZ down but that is wrong.
  
  All speakers have always been measured one of two ways. Back in the day they used to measure all speakers @1 watt/2.83 volts at 4' through the years sensitivity decreased so they moved the mic closer to the speaker, so todays standard is still @1 watt/2.83 volts, but they moved the microphone one foot closer to increase sensitivity so industry standard today is @1 watt/2.83 volts at one meter.
  
  Please do not think John Atkinson measurements are off I assure you they are spot on, and John is very knowledgeable and is not going to make mistakes he learned to measure from speaker designers over the years and he is doing everything right. He is one of the consumers only hope for the truth because the manufactures certainty are not going to be 100% truthful it will hurt their profits.
  
  And these like many other speakers have been independently measured and those measurements posted online, and they are the same absolutely horrible !!!

  what I find most challenging is the artificial brightness.

    In order for sounds to sound twice as loud you have to increase the volume by 10db so that 8db peak you pointed out is insane its almost twice as loud of the average response.
