Choosing new router

sounds like the speaker is not shielded against EMI or you have a radiating source too close. Try moving wireless transmitters further away. If these are shielded speakers, then replace the cable with a correctly shielded one.

The router is 50CM away from the speakers, that is the maximum I can do. It still does that PSSSSS and sparks noise (It is very weak noise, but still annoying).
My speakers are not shielded I guess, they have Non Polarized AC Plug, I have seen on another forum I need something like this to fix the issue https://www.amazon.co.uk/dp/B015J289ZG/?tag=smallncom-21
its called mains conditioner, what do you think ?
It has something to do with the electric because if I disconnect the RCA cables it still does that till I completely turn off the speakers (or the router) so it stops. Do you think the mains conditioner will fix the problem ?

unplug all electronics one by one and see if/when the noise goes away. See if it is a wall wart power supply or a device. If it does not then, you need some sort of RF filter on either the power or shielding of the the speaker itself. a simple ferrite core choke on the power cable at the speaker may be enough. Or use a power filter. i would start with an inexpensive one.

The router is the cause. If I turn it off the speakers doesnt do the sparks. I biught the mains conditioner if it doesnt work I will return it back to Amazon.

Try plugging the router in a different power outlet to see if it makes any difference. I've seen cases where the actual source of the problem was the power bar itself where the equipment was plugged.
