[ACOUSTIC SYS]
well, who doesn’t know, speakers are such structures made from
who are singing something. and the speaker usually sings in them.
the speaker itself cannot sound good (if
just put it on the table). although some do.
So you can check it now to see if it is working properly.
and for it to work normally, it must be placed
in some building.
currently not in iron, of course.
speakers in plastic cases sound much worse than
in wooden ones. Multilayer plywood is also okay by the way!
(also a tree).
right now I'll tell you how I made minecolumn that stands
under my desk, which I listen to every day
spekk. and not the current one, my mafon sometimes I come to this system
I connect when no one is home.
this all sounds very, very good.
as I mentioned earlier, I got hold of a twenty-five-watt
speaker, but not a simple one, but a low-frequency one. I just love it
low-frequency sound... and the amplifier made it suitable
power and quality.
in short, I didn’t make a case for it from scratch
try, because I wasn’t sure of a successful result,
so I dug up a broken column inside
rectangular in shape (even two, I threw out the second one) and
I left the current frame (so beautiful, polished).
the column is not very large, medium in size, there is one
some not very powerful speaker probably lived, watts per
approximately five. (when she got to me, then there finally
no one lived).
oh well.
frame - this is without front and back panels. front
it wouldn't fit anyway, and the back one wouldn't fit me either
I liked it, it was too thin. back panel i
I made it from such a slab, like a wood chipboard
called, which is made from compressed sawdust, from it
they make a lot of things, it’s not difficult to find, even if it’s furniture on the street
some old thread, for example, or something like that.
and the thickness of these panels is one...two centimeters, in general
so thick. and cutting is not difficult.
well, I cut out the back with a jigsaw of the required size
panel, and the front one is the same. it's more difficult with her because nada
It was necessary to make a round hole in it for the speaker. then
measured the diameter of this very speaker (I have -
fifteen cm!) and drew a circle with a compass,somewhere in
the middle of this panel. and then drilled a hole in it,
I stuck my jigsaw into it and started sawing.
I'm tired of it, the panel is thick. and then I finished everything and
I applied the speaker to the hole and noticed that it had been sawed off
It’s a bit crooked, I had to straighten it all out with a file. I'll flow
a little - I'll attach the speaker and check how things are going there.
In short, it took longer to level everything than to saw it. a
this happens often.
then I drilled holes for the screws that the speaker
crepizza. a marked the places where there are holes for them
so - I just applied it evenly to the freshly drilled hole
and poked it with a pencil into its mounting holes.
I carefully outlined where to drill them. and drilled it. at
By the way, the holes are healthy, eight mm each, I’m
I was still in college, and all the desks were held together there
such beautiful bolts, just eight millimeters!
nonethe desk did not fall apart in the end, because I took it off
each has just a pair of these bolts (they also have nuts
even came in handy).
and I attached the front panel itself to the kapkacy with the same
bolts, positioned them symmetrically of course. then I also
I heard that when the speaker has phase inverters, then it
sounds cooler.
these are like these holes in the front panel of the speaker, in them
It is also advisable to insert some kind of tube (well, not
iron is clear), it should create a type of tunnel
inside the column a do not stick out from it.
and its length for each column is somehow protected. by
some very complex formula... well, let's get over it
I didn’t want to run to someone to find out, I’m just in
front panel cut out two round holes on the sides,
five centimeters in diameter and inserted two
a piece of plastic pipe, ten cm long.
currently the holes for them turned out, obviously, crooked and while I
I trimmed them, they became slightly larger than they should have been
diameter My tubes in them began to dangle. well I'm tada
I bought a tube of glue, as I remember right now - special glue NT88,
yellow, like “moment”, but just paste it on
the pipe wouldn’t have worked out (the hole was too big), then I thought
- I thought and finally came up with an idea - I took a rag, cut it out
a strip of it, lightly coated it with glue and wrapped it around
tubes, about three turns I made.
When the glue dried, the tube had difficulty entering
hole, the rag did its job... I anointed it and
glue on the outside and stuck it into the hole. and it's ok
everything stuck, tight and even, I like it, three years
no longer falls off...
then I found out that I still need to make a filter so that it
low frequencies passed to the speaker. there's a reel there
with thick wire and a healthy capacitor. well you can
create it at the input of the amplifier, there the current is made from
several resistors and capacitors,but I wanted
so that it is in the column, otherwise it will suddenly be needed
connect it to an amplifier that has this filter on
there will be no entrance...
and finally, it won’t hurt in any case. I found
some magazine with such a filter, I redrew everything for myself
and went to do it. a reel of the required size made of cardboard
glued it together, unwound the wires of the desired one from some trance
diameter and number of turns wound on this coil.
Well, of course, not turn to turn.
then I connected the whole thing, check how it works,
but it hardly plows at all. in short, I'm with reels
I'm not friends with these. I got angry and threw it somewhere
further away. and then I was in a stall (musical)
filter from a broken column (a healthy one)
unscrewed it. easy and simple.
there were three of them, for three speakers, I barely found the one I needed,
the speakers themselves were no longer there. Well, I put it to
to yourself. it really works. NotI did the same!
I don’t feel sorry for you.
I cut out plywood for this coil with a capacitor
a small stand, secured it all and her
screwed it with two screws (or one?) inside to the wall
columns.
and it looks good.
I also found out that you need to hang a piece inside the column
cotton wool, it really softens the sound. no way
fill the entire space inside column a nada with it so that
cotton wool took up about a third of its volume. in short, don’t protect
difficult.
approx.
It’s not easy to push this cotton wool inside the column,
a wrap it in gauze, like so that you get such a lump.
and it would be advisable to hang it on strings inside so that
he was hanging there and not lying there. well it's simple. and I also found out
that you can paste the walls with something soft, for example
felt.
For some reason there is no need to glue anything to the front one. well what -
I found a felt boot from a friend and cut it into strips
(with ordinary scissors, by the way, it works) and glued it
the same glue. stuck fine.
here the tube ran out.
a I pulled a piece of fabric onto the front panel, it’s fine
It looks so good, black, dense, pleasant to the touch.
synthetics, I'm not particularly into themI'm figuring it out. in general
beautiful.
a nailed it along the edges with small nails. yes even
the bolts on which I screwed the front panel hold it,
I first stretched this fabric and nailed it down with nails.
then in the places where these bolts should be inserted
I dug the holes and put the bolts in there.
I was picking something sharp into this fabric first
stuck a pencil, like, threads in this place
moved apart (the point is not to tear this fabric), a
then I put the bolt in there.
I connected a long, black, three-meter wire.
I placed the speaker under the table with the Spectrum, and the amplifier
also under the table, on the right. sounds great that's all
soft and wet, I really like itI like it!
well, I told you how I made my column, maybe
will help someone, or just curious to know...
