Guys, have you had any speakers where the audio macam come and goes on either the left, right or sub? My Swan H4+H10 has this issue

Feel sayang to change just due to this issue as when it works, it sounds as great as it did when I first got it 8 plus years ago, but when the issue happens....

for example left and right got sound, suddenly left will disappear, and when i unplug replug the left speaker (each speaker and sub has its own power plug) it will come back but go off after a while.

the sub has a crossover switch (like the lever where you can push up and down), if I play around with the switch to find the "sweet spot" every thing will work, but after a while it may happen again. So funny issue which also happens thru phone 3.5m jack so i don't think its related to my source which is a Xonar DX on my PC

wanna bring to repair shop also susah, since overall weight around 30kg

reconnect many times already

Yes I replaced all the RCA cables and also the 3.5mm cable which connects to the sound card. Thought it was fine but started happening again shortly after zzzz.

I think your theory about the switch may be correct. Nowadays i need to play with that toggle for it to come back on all 3 speakers. If i disturb it further I will get certain component disappearing again.

Maybe need to put wd40 XD
