RCA cable that gets the job done
Size: 10 Feet, Size: 10 Feet
I purchased this RCA cable to connect a powered subwoofer to my soundbar. The RCA cable works just fine and no issues with audio quality or connectivity. The cable is thick and heavy duty. The quality is very nice and doesn't feel cheap. The length of 10feet is more than enough to connect to subwoofer from the corner of the room to the soundbar that is in the center of the room.

Good cable for sub
Size: 10 Feet
Works great, the connectors seem a bit loose but they work really good. I compared it to the last less isolated cable I had plugged to sub, and very tough to tell but this cable does give a very slight boost in volume & seems to have good clarity.

Good cable for our sub
Size: 10 Feet
Bought this to replace a random RCA cable that kept giving us problems. This cable seems to run the sub much better.
