Although I also
posted the same on
the tread entitled "Stereo Bass using subwoofers", please allow me sharing it here again.
Even though just personally this type of synthetic music is out of my preference, I downloaded the intact mp4 video by 4K Video Downloader for analysis.
I extracted the sound into intact aiff format using JRiver MC28, and loaded the aiff file into Adobe Audition 3.0.1 for analysis. The entire track spectrum is;
Then I selected the 1:05 - 2:20 portion for Fq analysis;
Averaged Fq response of 1:05 - 2:20 portion in 20 Hz - 20 kHz scale;
And also in enlarged 20 Hz - 200 Hz scale;
I also analyzed the 1:05 - 2:20 portion in FFT size 65536 (which enables precise Fq response down to
ca. 10 Hz, and shown in 10 Hz - 80 Hz scale;
I analyzed the 1:05 - 2:20 portion in FFT size 65536 (which enables precise Fq response down to
ca. 10 Hz, and shown in 10 Hz - 80 Hz scale and in -9 dB to +39 dB vertical scale;
Of course, I heard the track by
my multichannel multi-driver multi-way multi-amplifier stereo system in latest configuration, and found the sound in my listening environment is just reflecting the above measurements.
Edit:
There are only
ca. 1dB R to L differences in 16 Hz - 24 Hz and 32 Hz - 35 Hz area, as you can see in above spectrum. If I would get very close to the sub-woofers, I may feel the differences by my body or hand placed at the bass reflection port of my Yamaha YST-SW1000... Will try it soon. Just for your reference, relative gains for L & R sub-woofers are very carefully fine tuned to be equal with each other.
