Measurement and Data
||Left is a frequency response curve.
Data shows very flat output from 40Hz to 1000Hz. It isreally hard to obtain
accurate low frequency datain regular listening room because of the effect
of standing wave in a room. Also, we have to think about the effect of
1, 1/2, 1/4 space question.
Anyway, this is near fieldproperty. Therefore, loweredge output will increase
in far-fieldlistening position, I suppose.
||Right side data is a impedance curve.
As you can see, around 35Hz is anti-resonance point. There is no outstanding
reflection in the enclosure. Therefore, I can remove a little bit of sound
absorption material, rock wool in this case.
Since impedance in higher frequency goes up soundly, we can cancel these
by impedance compensator
