Back to LFG
Gayo and Robusta
This is the third
time a test ride has been heard in Mr. N, after the Power 180 hearing test and the Power15n
test, this time I came to Mr. N to test my latest product namely Low Frequency
In this review I
do not want to discuss how the voice character of Mr. system
I have done in the previous hearing test, which this time I want to discuss
is Mr. coffee dish. N and also the performance of LFG for improving
the sound system. N
N is a
coffee connoisseur, so every time I come to Mr. N I always get coffee from Mr.
N. As I recall three
types of coffee served by Mr. N on my arrival, the first is Mandailing coffee,
the 2nd Arabica and the 3rd I forget what kind and the fourth time this
is a coffee blend which is a mixture between coffee Mandailing, Gayo and
Robusta which formulated according to Mr. exclusive formula.
According to my
tongue, coffee blend Mr. N has a taste similar to my favorite coffee Toraja
Kalase which has a bitter taste, not too hard, a slightly sour taste but
does not trigger nausea in the stomach. Incidentally on the day of this hearing test
is carried out a bit cold weather conditions due to heavy rain, so enjoying
Mr.Ni's blend of coffee while trying LFG gives me a happiness.
N your coffee is
amazing .. !!!

Mandailing + Gayo + Robusta
In the test with
LFG we tried LFG based on 3 parameters those are:
1. In terms of setting
2. Position of LFG
3. Type of output
waveform to get the best improvement.
Setting the level
that we first did was at level 80%, according to Mr.
N at this level
sounds sounded so stuck or if you can borrow the term digital audio format
we can say as a compressed voice. Then we try to level down gradually and we find
that the optimum level is about 35-45% for Mr. N room size of 4x6 m2, of course this is a new
experience for us both.
If applied to a
room of the same dimension, but in different places, with different systems
and with different music-listening preferences, it may be different levels.
LFG at Level 35%
In the hearing test
based on different positions, there are three positions we try:
1. Position in the
left rear corner
3. Position on the
three positions are seen from the sweet spot or spot of the main hearing
On the left and
center of the LFG position is placed at a height of about 1.5m from the floor.
In the middle position
of the LFG is placed facing the area between the speakers and the sweet
Overall, no position
where LFG does not produce good results, in any position the LFG always
gives an increase in the voice quallity. What is different is the level of quality improvement,
certain positions provide more improvement and other positions provide
less improvement. We found that placing the LFG in the middle position
facing the area between the speakers and the sweet spot is the position
that produces the best improvement.
In the picture below,
LFG is next to the senior product that inspired me to create LFG RR-777
from Acoustic Revive.
that also makes me happy is that I find that although LFG is placed on
the floor, LFG can still provide improvement, because generally others
LFG like products are always recommended to put in position about 1.5 from
the floor, this proves that the iron core choke antenna used in LFG is
able to make LFG emission waves become more powerful and efficient.

After we have tried
LFG based on placement, then we also test LFG based on output wave type.
In this trial I
see that Mr. N is excited about changing the output waveform
, I think for Mr.N LFG is a fun new toy for him because
it can test in various positions and variations of wave type.
trial we only play the CD and do not rotate the Turntable, and we assume
that it may take different level settings and wave types to use turntables,
maybe even for songs with different recording and music characters will
also need different settings , for a true Audiophille of course this is
a pleasant condition. Especially if in the future I find a new wave
of different types, then LFG will be a more interesting toy for a true
The most tested
hearing test parameters we tried were to try 5 wave types supplied by LFG.
If at any time
you have an LFG you may have a different positive rating, so LFG can make
the world of audio to be as beautiful as a rainbow filled with different
Briefly below are
our subjective conclusions regarding the performance provided by the LFG.
Mode 1, Schuman
This mode is the
mode that Mr. N makes the most natural sound system, clean,
stereo image and depht become wider to left right and back
Mode 2, Sinus 7.83Hz
We are of the opinion
that in this mode the vocal sound becomes subtle, so it may be a tap for
a rough recording or for those of you who sound smooth / mellow vocals
Mode 3, Square 7.83Hz
According to Mr.
N This mode produces
sounds similar to mode 1 but the sound character of the improvement with
this mode sounds a bit dirty.
Mode 4, Sinus 10Hz
We argue that in
this mode the resulting sound seems rather fast, so we assume that this
mode is suitable for those who like to listen to classical music with many
Mode 5, Sinus 5Hz
In this mode we
find that the sound seems a bit slow or it can be said to produce the opposite
effect with Mode 4
Overall I see that
Mr. N most likes Mode 1 is Schuman 7.83Hz
