Hi ... I'll just tell you this ... This kind Diora is standing in front of me and has been using 4ohms for half a year now and she has already been to many events and walks very nicely ... it was connected to the SW stage set :D

Ps and as for these raisers ... I do not know why you are such supporters of turning off the contour ?? For me, the sound with an outline is cleaner and more transparent ... Maybe someone will convince me to turn it off?

you advise me to let ARV stay ... let it be so ...

I already have practically everything I need ...

One more question:

As everyone knows, there is 2x35W RMS power at 8 ohms
this
at 4 ohms it is equal to about 2x70W RMS
then I conclude that
at 6 ohms it will be about 2x52W RMS ...
Yes ?

You forgot about one important thing, which is too weak power supply - 120W transformer will not allow you to get such power You can get the maximum of 50W / 4? of pure signal from it.

My friend VeNi, no one forces you to turn off this tweeter, but if you heard really good quality loudspeakers that do not require this type of muck to make bass out of themselves, you would recognize the same as most people who are bothered by rumbling around 100Hz.

Oh, OK

and some of you have a page where there is a crossover diagram for ARV-104-04-8

I will start looking for something tomorrow ... but for sure I won't find everything ...

Guy! After all, I gave you a crossover for this ARVka and GDN! What do you mean? Do you read any replies to your posts?

relax... I know, I know ... I saw it and I have it on HDD ...

because you see ... in this diagram, L1 = 1.2mH ... thanks to this there is a division of about 3500Hz ... and I would like to have a division of about 3000Hz ... and I think that it is enough for me to increase from 1.2mH up to 1.3mH

the problem is that there is no such coil for sale ...

and now the question:
maybe I would connect 2 coils together so that they were together equal to 1.3 mH? good idea ... it will work ... can you?

2 question:
What is RDC? (one of the parameters in the coils - expressed in ohms) explain to me because I have to choose the right parts for my verse

Rdc - if in [?], then probably the coil resistance for direct current.
Look, maybe you will find a coil as needed. If not, you can unroll a bit more. With the rest of 1.3 and 1.2 mH it is not a big difference, it would probably be difficult to remove it in the listening experience.
You want a lower cut - give a larger voice coil for the woofer. Do not try too hard with the tweeter, because with a lower cut, the power strength will be lower. You will have a tiny slump in the characteristics - "withdrawn" midrange.

I mean cutting from the woofer ...
at 1.2mH it is around 3500Hz
at 1.5mH it is about 2500Hz (I've seen graphs with such a crossover)

and i need about 3000Hz

then how? can I connect 2 coils together so that it gives me 1.3mH?

You can connect 2 coils. If they are not magnetically coupled (close to each other / parallel axes) - the resultant inductance will be the sum of the inductances of individual coils. If, on the other hand, you place them too close to each other, they will interact with each other and depending on how they are located in relation to each other, the resultant inductance will be greater or less than the sum of the inductances of individual coils.

All the better for transistors in the power amplifier :)

and will it be that:
How do I connect a 0.4 ohm RDC coil to a 6 ohm speaker ... the speaker will behave as if it had 6.4 ohm?

Not quite ... the coil will do as a crossover here

well ... like a crossover ... but from what I know, "the impedance of the speaker will increase" ... as if ... no?

If you connect any resistance in series with the loudspeaker, then the impedance as seen by the amplifier will of course be larger by an appropriate amount. The overall goodness of the loudspeaker will also increase slightly - Qts - as described by Igod here: http://diyaudio.pl/articles.php?id=5. The so-called damping factor, a bit. However, there is no need to worry about these two things, as long as the resistance in series is much less than the impedance of the speaker itself.

and thanks to this, I have a problem with my head that at least 8 ohms can be connected to my amplifier ... and I will buy GDN speakers that have only 6 ohms ... ;)

Added after 17 [minutes]:

Well, that's about the speakers and crossovers ... now I can start buying and assembling it all ... although there is still the housing ... but the time will come for that ...

if I make the columns, I will write reviews ... (+ photos) ... with thanks and paste it here

thanks to everyone for your help ... especially JS

Apart from the boost, the opposite phenomenon can occur - for example on old cassette tapes ... Input is not controlled. And then you can shoot to the max without using any equalizers and we still have no imaging.

I gave an example signal with the only true setting - all set to zero. The lack of linearity of the potentiometer characteristic can be corrected by playing somewhere on the half of the output power (i.e. where the Loudnesses do not work)

Helpful post? Buy me a coffee.

-> El Liero
Do not try to install a coil with Rdc = 2ohm, because you will worsen the bass control. Rather, assume that the amplifier will be fine on 6 ohms, as this is not a cheap Chinese tower. Besides, the amp's transformer won't allow for more.

And can I connect the 4? speakers to the DIORA WS 502 amplifier, which writes 8?? Nothing's going to burn ???

Look for! The topic was discussed also in the context of this amplifier.
Standard answer:
If you listen quietly, nothing should happen. However, if you play it loud, such exploitation will cause faster wear and tear up to and including the destruction of the power amplifier.

I deviate a bit from the topic, but I want to come back a little. Which potentiometers are better. From which group. Regards

Conrad Pihery - cheap and good.

Generally, B is used for audio, but it may be different in the case of foreign ones. Retailers usually know which to give, like you say to adjust the volume.

Topic summary

The discussion revolves around connecting 6 Ohm STX woofers and 8 Ohm TVM tweeters to a Diora WS442 amplifier, which is rated for 2x35W RMS at 8 Ohms. Users express concerns about the compatibility of the 6 Ohm speakers with the amplifier, which specifies a minimum impedance of 8 Ohms. Several participants suggest that while it is possible to connect the 6 Ohm speakers, caution is advised regarding volume levels to prevent distortion and potential damage. Recommendations include using a low-pass filter to slightly increase the impedance of the woofer and ensuring that the amplifier is not pushed to its limits. The conversation also touches on crossover design for the setup, with users sharing insights on different crossover types and their implications for sound quality. The need for careful selection of components and monitoring of amplifier performance is emphasized to avoid overheating and distortion.
