The issue persists with all subwoofer kits, I must have missed that product page. But we cannot ship to your region unfortunately.
The issue is that the power supply of the Rythmik amps often cannot properly handle 220V mains, usually creating a persistent hum that can't easily be fixed.
Due to this issue, and the ongoing chip shortages, Rythmik isn't currently able to work on a version capable of handling 220V regions.
They have also recently asked us not to ship any amps to those regions.
We dont know when or if Rythmik will have a permanent fix, as it may be dependent on the chip shortage subsiding.
