I am using the cable so far very satisfied. For the length of 5 meters, the price of just about 10 euros in my opinion perfectly fine. The processing does not look cheap and the cable can be bent relatively well without going the same broken. I use the cable to my devil Sub (US 2110/1 SW). It crackles nothing and I have a clean, clear bass.
Conclusion: Whoever manages without Oehlbach and Co, which was accessed here.
