Pioneer Headphones: Identifying + and - Polarity on Wider and Narrower Inscriptions

Hello.
My question is very banal, but unfortunately it causes a lot of trouble for me, so recently I bought pioneer phones on the exchange, as it turned out, after opening the pad, there are no instructions .
Now there is a problem where to connect + and where -, so there are no markings on the speakers, only the inscriptions differ
- one is wider
- the second is narrower
Help me please, which is a plus and which is a minus.

As a rule, it happens that:
- wide connector +
- narrow connector -
However, if you connect them relying only on the wires from the radio or amplifier (i.e. plus from the radio to the wide connector, minus to the narrow or plus to the narrow and minus to the wide) it will be indifferent to the speakers, because they will still play in phase.
Regards

if I connect the other way round, nothing will happen to the speakers?
Besides, when I tried it, I noticed that after a narrow plus and a wide minus dish, all the time trembled, not only with the bass. So I decided that wide is a plus and I hope it will be good

hmm, in general, nothing should happen to them
one should only remember that the "natural" first movement of the speaker diaphragm along with the voice coil is forward and then backward
therefore, with a strong impulse and reverse polarity, there is a possibility of mechanical damage to the coil by the magnet

I will say that my speakers are pioneer TS-A2065, maybe someone has the same and he has an instruction or for sure wide is a plus

You do not need any manual that you will never find in a Pioneer loudspeaker. It's just not there. You can check the phases on the speakers very easily. By setting the fader on the speakers you want to check and moving the balance to one side you can notice an increase or lowering the sound quality (bass). If after setting the balance on, for example, the right side of the speaker, if the speaker transfers bass better, it means that you have incorrectly polarized phases. At this point, just turn the cables in only one of the speakers and everything will be OK if you can hear a reduction in sound quality with balance regulation it means everything is OK and the phases are correct.

I think I wrote it quite simply and understandably.

I check the polarity of the speakers (of any manufacturer) in the following way: I take a 1.5 V battery or other DC voltage source of such value and connect it to the loudspeaker. amplifier.

Hehe no fact, the easiest way, and I forgot about it . I might add that sometimes a dot is painted on the basket that signifies the beginning of the winding (i.e. plus).

I will refresh the topic a bit, because I also have a problem with the phases in the speakers. In the car (Audi A3 8L) I have the original Bose sound system. 4 speakers in the front, 2 in the rear and a horn in the trunk. I used the MARTIINO method, and it turned out to me that in the front the left speaker plays without bass (the tuba does not turn on), the right speaker plays with bass (tuba plays), while on the back the left speaker plays with bass (with tuba) and the right one without bass (without tuba) ). I don't know much how to interpret it. Please help.

Maybe it must be great
