[Music]
what's up everybody this is aaron from
aaron's audio corner
and this is a video showing you the
steps or some of the steps
of how i measure speakers using the
clipper near field scanner there have
been
questions and sometimes i think people
maybe just don't quite
understand what the near field scanner
is now this isn't a tutorial
of any nature or anything like that it
really is more just a
hey here's the process that i go through
when i conduct my measurements now
in this case i am testing the cali in8v2
as you can see it's
currently on the stand behind me and i'm
going to start off with what i'll always
start off with is i take the speaker
i put it on the stand step one done
then i go through this process of
connecting all the wires so in this case
it's got the power cord
input and it's got an xlr input as well
those wires come
up through this tube and this tube
extends down to the bottom
and it runs out and those wires are
plugged into the clipper machine
clipping machine is on my computer desk
stand that's over here i'll show you
that in a second
and then that way you know when this
doohickey spins around the speaker to
measure uh the wires don't get tangled
up they're all
taken care of and sealed up in here they
come out the back
and they route into the speaker after i
connect the speaker
wires what i do is i make sure that the
speaker is centered up on the stand so
there's a metal stand right here
and i put the speaker on the stand i use
this yardstick
and i just walk around and make sure
everything is lined up well
why do i do that well it's pretty simple
if i were to
put the speaker off center and then send
this thing around and i told it the
origin point was at the center
well the measurements would be off
center so for example
uh if the speaker were let's give an
extreme example if the speaker were
pushed
two inches to the side well the
microphone center location
would be like right here
instead of at the tweeter and obviously
that wouldn't be a correct measurement i
mean that just makes sense
same thing goes for the vertical
measurement you know you want to make
sure that the speaker is
flat on the stand you don't want it to
be tilted one way or the other
i mean this is pretty common sense stuff
but make sure that you
put the speaker in the center of the
stand you just you know use your
yardstick or a
ruler or something like that and always
make sure you do that first because you
want to make sure that you set the
speaker up correctly the first
time you don't have to go back and
re-measure it another thing that i did
with this particular setup
is i'll talk to this camera over here if
you notice
the microphone boom stand thing here
it's got some
felt tape around the stand now this may
look kind of gaudy
and honestly yeah it probably is but if
you go back and look at one of my videos
i created previously and i'll put it up
here in the corner
uh what i talk about in that video is
the microphone boom that comes with
the clipboards it's more regarded for
engineering purposes
but since i'm not engineering and i'm
not r d i'm
publishing data for everybody to see i
wanted to make sure that my data is as
accurate as it could possibly be
and therefore i got rid of the little
microphone boom holder
because that was causing comb filtering
effects above like i think two kilohertz
or so
and i made sure to put my microphone
through a tube this is aluminum tube
and then i just secured it in with some
felt tape here to make sure that the
microphone stays in place but also that
there's no really hard surface edge or
anything like that that could cause
additional cone filtering so in regards
to how my
measurement system is put together it is
a-ok
i made sure to make sure that everything
was set up properly
before i even began doing my first test
just for what it's worth
after i have made sure that the speaker
is at the center of the stand
then i go to my computer setup so i'll
spin the camera around show you guys
what i'm looking at
right now and that's it now it's it's
dark but what you can see
here is my monitors it's just a 22 inch
samsung monitor i've had it for
no joke probably 14 or 15 years
seriously and then i've got a dell
laptop that i'll run
the computer stuff or the clipper
software through and then i'll show you
where the clipper
hardware is and the amplifier that i use
so
down here is the clipper box
and that's where all the ios run through
so the the power cable
the amplifier cable the signal cable all
that stuff
and if i'm doing powered speaker testing
i don't need anything else other than
this
but if i'm doing passive speaker testing
then you need an external amplifier so
in this case this is my external
amplifier
and the signal is routed to there
basically to provide
additional output comes back into the
clippers so the clipper knows what it's
going
out and uh it can account for any kind
of losses or anything like that in the
line
luckily you don't have to worry about
that uh let's see here
then i go to the clipper software so i'm
going to kick off this screen
recorder here and i've cheated a little
bit
i've already measured this speaker once
before did a couple days ago so i'm just
using the same template that i was using
before
and i'm just going to kind of quickly
show you some of the steps that you go
through to make sure everything is good
now
there's an initialization process that
you have to when you turn the clip on
for the first time or once it's been
uh disconnected from power you have to
initialize it and that
basically just gets the clipper you know
to
understand its bearings so to speak so
it says you know
uh i'm this far out in the r axis or i'm
this high up you know it you tell it the
limits that it can go
and you set it up that way it's very
simple but that's just the
initial portion of testing then you get
to
what is the calibration point this is
the second step
that you go through and in order to make
sure that you move the microphone to
each of these individual points that you
want to
set up you would go to manual movement
so now i'm in manual movement and
clipple
sends out this really neat little remote
and this remote
actually controls i'll show you
the near field scanner so
with the remote i can control
uh the different location of the
microphone so right now
you know i'm moving the microphone
inward toward the speaker but what we're
going to do right now
is start off with the calibration point
so i'm going to say well let me cancel
this first
i want to put the microphone at the
calibration point talking to you camera
so what i'm going to do
is i'm going to bring it to the z-axis
i'm going to bring the microphone down
and i'm going to get down here
and i'm going to wait until it gets to a
decent point and we'll stop it
now i'm going to switch back to the
r-axis remember i'm doing all this from
the remote
pretty neat
and okay so the calibration point is
this
metal thing right here matter of fact i
can take it out for you if you want to
see it
i'll hold it up to the camera
that's a little calibration point so it
sits inside the clipboard the clipboard
software knows where it's supposed to be
relative to the center
line and you just make sure that you're
matching it up correctly
all right now my r axis is correct it's
right over the tip of the cone
and i'm going to push this twice i'm
going to get to my z-axis
and i'm going to bring this down and set
the z-axis right on top
and actually it looks like i can back
this out just a tad
uh the other way there you go and that's
pretty much perfect so i have set up my
calibration point in the clipper
software
and this is from an old test i'm just
going to hit set new origin
at calibration point okay that's fine
uh save yeah i've already done all that
so i just need to confirm it
yeah normally what would happen uh if
this were brand new run
let me go find a camera guy if this were
a brand new run i wouldn't have these
series of
points already loaded in the software so
it's going to ask me to confirm if i'm
if i want to make sure that
these points are okay and it is normally
they're all blank and it doesn't pop up
with a confirmed symbol but
i'm just saving myself a little bit of
trouble using the template from last
time
all right now the next point that i have
to measure is the critical point bottom
and what that means is basically get as
close to the pole as you can
without hitting any wires and in this
case you can see i've got a couple wires
back here i've got them velcroed
out of place and i'm going to go
up
oop let's go this way there we go all
right i'm going to go up
i'm going to go to a point in space on
the r axis
and this would be pretty close to it now
i'm not trying to go for absolute
certainty here i'm just providing a demo
i've already done the measurement
and we're going to say this is my
critical point bottom i'm happy with
that
and the next point would be the tweeter
point
and while i'm thinking about it let me
set this back to zero
okay tweeter point i'm one more r access
i want to back this out
twitter points now i need to go up
and i need to put the microphone right
at the tweeter
and that's pretty good z-axis now i'm
going to move this inward
got to be a little bit careful here so
right now i'm just a touch too high
so what i'm going to do is i'm going to
bring it down a little bit
and that's pretty good in line with the
tweeter now i want to back it out to the
baffle
they say about five millimeters or so so
that's pretty close
put it right there twitter point
okey dokey i'm gonna skip starting point
now reference point is the interesting
one
in the clipable software you set the
tweeter point but you also set a
reference point because they can be two
totally different things for example
most two-way speakers with a mid woofer
and a tweeter
the reference point will be the tweeter
point but let's say you have a wave
guided speaker with
a large eight inch woofer and a large
waveguide
dome tweeter a lot of speaker designs
like that
their reference point like their design
axis the way that you're supposed to put
your ears
on level at is the center point between
the mid woofer and the wave guide so if
this were something like that
then my reference point would be
different than my tweeter point
but it's not like that this is a
concentric design and my reference point
is the tweeter line so i'm actually just
going to move
the uh r-axis let me check this can you
keep up where i'm at right now
uh let's see r-axis all right i want to
move the
reference point basically the tip of the
microphone
to the baffle right in front of the
tweeter well not right in front but at
the tweeter line
but in the baffle space because the
point of origin of the sound that
everything should be referenced to is
right in front of the tweeter
right on the baffle and that's what i've
done here
and i'm going to hit save
and reference axis
reference axis that's pretty easy that's
the uh that's the plane that you're
going to be listening on and most of the
time it's
you know out in front of the speaker and
in this case yeah it is out in front so
the reference axis is going to be
that way away from the speaker so i'm
just going to move him outward
some number doesn't matter how much i
move them out clippable software knows
that i've moved it in the r-axis
so i've done that orientation vector
orientation is the
above or below the speaker so the
speaker is standing up and its
orientation is
vertically so i'm going to change the
orientation vector by
moving the microphone up okay
so there's my orientation vector it's
going up
pretty simple save
now starting point is the one that um
i won't say tricky but it's just
something you kind of need to pay
attention to so starting point defines
the starting point of the cylinder that
the clipper scans around
and by that i mean the clipper point the
clipper has a point in space that says
all right
this is the closest that i'm going to
get to the speaker
you kind of define something at the
bottom down here but it's different okay
so this is the closest point that i'm
going to get to the speaker in space
and my other measurements are going to
be based from that point
or backwards if you do a dual scan uh
and that's something else that would
probably
need to be discussed later on i want to
keep this kind of simple
so in order to set that up i'm going to
set my microphone up at some point in
space
above the speaker
uh and it it's somewhat arbitrary i mean
it's not fully arbitrary
but it is somewhat arbitrary where i set
the
uh starting point the clipper software
or the manual i believe says five to ten
centimeters
uh that kind of varies for some speakers
so in
some cases what i found works better is
placing the microphone further out to
make sure that you have proper summation
of a base driver and a port or multiple
base drivers in this case i do have a
large base driver
and a pretty decent size port so i want
to put the
r-axis point pretty far out and also
another thing is i don't really want to
put the microphone too close because i
don't want to get into the point of
potentially run into some distortion
artifacts from the microphone i mean
it's spl limit i think is 130 or 140 db
so you'd have to be pretty close but i
just you know it's another risk that i
kind of stay
mindful of so now the starting point is
set let me kick this off
starting point save alrighty
and i'm going to hit ok because i've
done everything that i wanted to do
now i go into edit setup
and you normally would test the speaker
uh test the outputs so what i do is i
use 4x averaging and in this case i've
already determined that 0.2 volts gets
me about 86 db
uh at 1 meter so that's going to be my
output voltage setup and then comes the
uh measurement array so how many points
in space do you want to measure
and here's the thing about that okay the
number of points of space that you
measure
can be anywhere from like one to i don't
know probably several thousand if you
want to do that the
the more simple the speaker is the less
measurement points you need for example
a subwoofer maybe needs like 100 points
this is actually covered in the manual
pretty well so i'm
trying to recall from memory uh more
complex speakers may need
a thousand two thousand twenty five
hundred for example the jbl hdr 3800 i
think i measured either 2200 points
or 2500 points a speaker like this
1000 points of measurement in space is
enough to define the spherical
uh balloon i guess if you want to call
it that of the
sound so the sound field and then from
that i'll
extrapolate the cea or cta 2034
measurement specifications
so i've done that i've set the number of
points
already i need to run this array
and it is done and now what i would do
is i would just say start so before i
start i will need to move this phone
now what i'm going to do is i am going
to start the process for measuring the
speaker
and i'm actually just going to do a time
lapse once this thing kicks off but i'll
show you the first few measurement
points
then we'll do a time lapse and then
we'll come back now i'm going to talk
through this because as i said before
i've already
measured the speaker so we're going to
look at the results of
the measurement that i've already
conducted but i just want you to kind of
see what's going on here
so the clipable machine is going to a
starting point behind the speaker and
now it's going to come forward
and it's going to measure above the
speaker it's going to measure in a
couple different places so let's let it
do its thing it's going to be kind of
loud so cover your ears
your little click microphone or not
microphone but amplifier
worst worst worse
okay so there's five sweeps if you
counted them the first sweep is a
pre-loop it's just telling the system
hey i'm about to do some measurements so
everything afterwards
first one worst worst
everything after this first one you can
ignore then it's gonna do the four
sweeps and it's averaging those to make
sure there's no external noise worse
worst worst worst because if there's
external noise you don't want that to
creep into your measurement also it
helps to lower the noise floor
worse worse
so i'm going to let this run i'm gonna
time lapse a video on my iphone
i'll throw it in here and we'll come
back and as you can see
you know the the boom arm is spinning
around the speakers taking measurements
and in real time it's storing those off
into the clipper software and once it is
done with that what i can do is i can
take that data
and i can use it to define the uh
spinorama data set
which comes from klipple's module uh for
the listening window module so
it's one of the options in the listening
window module
and it's it's pretty much all automated
once i do that
and i verify that the data looks good
which just means that fitting error is
low
that there's no noise that creeped in
for instance like
if i was measuring overnight which i do
often and maybe a thunderstorm came
along
uh you know it could corrupt the data so
for that reason i would need to
rerun measurements and there could be
other things along those lines maybe a
very very loud car
came and parked out front of my house
and made a bunch of noise just something
like that you know you just never know
so you've always got to make sure that
the data makes sense and then once it
makes sense
i go to my next step which is to
do my distortion testing do my
compression testing
maybe my near field measurements just to
check ports driver break up
kind of get an idea where the crossover
region is let's see what else is there
i just do all sorts of other
measurements so that's how i get to
where i provide you all with the data
it is a process it does take time some
speakers are
more complex than others for example
i've got this
dan lee let me see here let me move it
out
good lord this thing is heavy
[Music]
can you see this let me check the camera
make sure you can see this
okay yeah you can see this i've got this
dan lee
sound labs this is the i think it's the
sh-50
and it is a big old speaker synergy horn
the acoustic center i can't even
remember where it is i'm gonna have to
ask tom to find out for sure
uh but yeah it's gonna be a complex
speaker i don't imagine that i'm gonna
get it right the very first time
as far as you know understanding where
the actual acoustic center is and what
makes
most sense with setting up the reference
plane i'm sure the reference plane is
probably dead center
and the acoustic center may be actually
the center of the speaker uh
or i should say you know back in the
throat of the waveguide
but it's just an example of a speaker
that's probably going to take a lot of
different measurements
to fine-tune especially when it spins
around at the back i'm going to have to
set my averaging
to at least 4x because if i don't do
that what's going to happen is
the noise in the room by noise i just
mean modal issues
are going to creep up they're going to
corrupt the measurements because i doubt
there's been
much energy thrown to the rear of this
speaker i don't know
i'd guess that it's probably not quite
omni at very low frequencies but it
could be i just
i truly don't know so that's why i say
that
some of this stuff is a learning
experience for me but i really just
wanted to share with you all
a an idea of what it takes to do the
speaker measurements and
i don't want to say that the near-field
scanner is idiot-proof certainly i've
run into
issues and especially learning curves
but i mean within like two or three days
i was off to the races and measuring
stuff and i've learned some things along
the way to help me get better at it
the folks at klipple have been great
answering my questions and
so i mean yeah it's it's a great
incredible piece
uh if you are a manufacturer and you're
watching this video
you may not be but if you are and you're
thinking you know i've got to build an
anechoic chamber you don't have to build
an edict chamber my garage i don't know
this is what 22 by
maybe 14 22 feet long 14 feet wide
uh i've got the near field scanner so
the one thing that i will
note is the ceiling is 10 feet so that
means that with the base
z axis which is the height portion of
the near field scanner
i can only measure speakers about as
tall maybe around three feet tall
36 inches so roughly a meter tall but
the cool thing
is that i added the rx r-axis extension
brings the r-axis out even further
another
about half a meter and because of that
what i can do and i've done this
i can lay tall tower speakers on their
side so i can measure up to about
i'm going to say maybe 50 inches is
probably
pushing it 50 inches tall lay a speaker
on its side and measure it that way
and it's cool because in the clipper
software all i've got to do is say
the orientation vector instead of up and
down now it's left and right
super easy super super easy um but if
yeah if you're a manufacturer and you're
looking at something like this
it's to me it's a no-brainer uh or
alternatively you can send your speaker
to warquin if you're looking for r
d work one up in minnesota michigan
one of those places up that way because
i'm in alabama so it's up that way
send it up there i don't know what they
charge but it's not going to be the full
price of a near field scanner
probably a couple iterations to help you
really nail down the process of
what the speaker that you're trying to
achieve should be doing
uh and those guys are great at that kind
of thing i mean they're they're
engineers so they're gonna be able to
provide you with
advice on what to do but enough rambling
for me
i hope that that gives you a good idea
of my process
how the near field scanner works and
that's it so
i will talk to you all later i hope you
have a great one bye
