So, Hello Everyone!

In general, I screwed up the speakers a little. It became much better to play than in the state in which they arrived to me. Although in a good way, it was necessary to think about the crossover, the midrange has a generally small diffuser stroke, or the resistance should have been hung in parallel, or played with the frequency, or something else. In general, I’m not particularly strong in this part. And not knowing the Z-characteristic of the speakers, I didn’t point my finger at the sky. And the crosses there are quite tricky for me. I wanted to remove a bunch of coils, resistors, resistors altogether, because... I think they spoil the sound. Well, I didn’t experiment at all. So it plays more or less and more money I wouldn’t have been disappointed, and time was running out. I might get confused myself, when radio equipment turns up. So the buildings are normal. I liked it. Made of chipboard, front made of 18 mm plywood.

Now the report.

They came to me in such a deplorable state:

The resistance was kind of coarse, and the speakers had different ones. It was then that I caught up. There were different midrange frequencies. In one column 6GDV 25 Ohm 13 cm! And in appearance it seems to be the same, but the GDS is 13 cm. One is jammed, so the differential does not move even when pressed. Well, it was clear that it had been wound, the glue everywhere was not factory-made, the second middle rattled when pressed. The housing under the midrange was broken in one. As I understand it, this is what they wanted to achieve more air. Everything is covered in dust and mold. In one column there were some children's rulers, balls, and pieces of plasticine all around. I forgot there were some cheap piezo HF ones screwed on top. Such ear cancer is worse than megaphones. Because There was only one HF 6GDV or whatever it’s called “yellow” one, turned off. In general, when I turned it on, I didn’t really know what to do with them; it was easier to think about throwing them away and buying speakers and reassembling the speakers myself.

Well, once I took it on, I had to somehow get out of the situation at an inexpensive price.

I started experimenting.
I took a car 4 ohm “silk” HF Ural.

I decided to break out the standard mesh, because... the grids spoil the sound, so they will be under the standard grid, and we don’t need two grids. As well as one. I didn’t want a full-time job at all. decorative plast. I wanted to install a wall of radio equipment, I wanted to putty it and cover it with film, but I didn’t have the film at hand. (Not this time.

And at the same time, I inserted food into the cups from other HFs so that they would sag and stick out and filled them with hot glue:

I started experimenting with low-frequency design, tried a round phasic longer than the standard rectangular one.

Still, there was something I didn’t particularly like.
I decided to stop at ZY. I cut out the plug.

IN seat they approached like family. But into the layer. the hulls did not fit and it was impossible to bore them there. At first I tried to mill out and remove the edge with a router, but I loosened it too much, but they still didn’t fit. I had to fix a small mistake with polyester. Strengthened the flange. And I decided to cut the housings a little and put the carpentry underneath. So the midrange will be screwed onto the plywood and as a brace at the front. and rear the walls of the glass will serve.

At the same time, the walls were glued a little with vibroplast and carpet with 88 glue, the front was missed. wall liquid nails...

I assembled the column, I press on the mid, look, the midrange is moving. I took it apart five times, I thought it was siphoning from under the wire. But then, as it turned out, it came from under the carpet, despite the fact that I stuffed the glass very tightly and the surface there was flat. In general, I poured 88 glue into it mixed with synthetic foam, such a mess, and probably coated the hole and cracks with liquid nails.

In the cross, I only replaced the wires incoming to the cross and to the mid by 2.5 squares:

Well, that's all. We assemble it, measure the resistance, it turned out as it should be.

I'm pleased with the result. But one GDN, at a low volume, the decel wheezes and rustles.
I'm taking it apart and figuring out the supply wires.
I began to move them, right in the place where they enter the diffuser, so it looked like a sore spot. GDN is from the 80s.) I used a soldering iron a little, everything became fine.

Well, I’m putting the front in place. cover. I glued foam rubber to the 88th.

Everything works, I’m happy with the result, it’s cheap and normal.

While I was writing the article now, this client called the person I did and said that one GDN stopped playing.)
I suspect that this wiring has finally broken off. He probably threw it properly, and this is the result.

I'll try to duplicate it with a second wire and solder it a little lower, where there's a through square. Tomorrow the mid will deliver.

And so they sound very decent and the bass was not buzzing and fast. Well, not very deep. Well, the speakers have a stated range of 40 Hz. From 40k they played normally. Well, pop. Infected Mushroom played with passion.)
Not for long though.)

Well, nothing. So it’s a good idea to replace one GDN for him.
