Before purchasing decisions especially the negative reports were important to me,
of which I can not confirm that right. Wearing my speaker system
the addition II, perhaps a revised version.
In fact, a slight buzzing sound heard when the signal input cable
loosely lying around "open" jack.
This buzzing sound disappears immediately when both input contacts to ground
are short-circuited. One must remember that the male end in subwoofer
Amplifier has a high sensitivity and an open input connector as
an antenna to the 50 Hz tone "from the air" captures.
It may be that the input cord is not very well protected, in my
Building it depends very briefly wound up at the output of my mixer.
Even fully up volume control I do not hear humming.
The build quality is good all around, visually, the system adds clean in my
PC space a, which is also often used for measurement purposes.
Now the important thing is the sound.
I have fed white noise amplifier, band-limited from 22.4 Hz to
22.4 KHz. The input level was chosen so that 75 dB (A)
Total sound Duck level at 1 meter distance showed.
Very surprising was the frequency response to pictured on the FFT analyzer.
In the heights beautifully linear, no waste to 20 KHz, the bass control was so
set that down to 40 Hz and here was a linear relationship. Though
is about 120 Hz, a slight elevation that will come in the near field
remained.
This sufficiently linear bass reproduction occurs when the regulator to 2 3/4
Points is. For the cheap price you can not expect that the
Volume control corrected aurally, others listening levels
then the bass content must be adjusted manually.
The symmetry of the volume control is the way sufficiently.
The advertised 360 ° surround sound I have not "found", but you can probably
Remove far from the central axis 0 ° without sonderlicher level waste
shall be measured.
These details will be seen that I am one of the listeners who no Wummerbass
also like the volume to be pleasantly with me.
Now followed by many sound samples with different music.
The Concierto de Aranjuez by the Modern Jazz Quartet MJQ, glorious as the dry
Bass goes down to E, or Radio Swiss Jazz, to name just a few.
These small, inexpensive plant plays amazing music, I would have
not think.
Of course, Logitech has not developed for a Mahler or Wagner since
must be ascended then already other formats.
All in all a buy rating for the envisaged purpose!
