A:Answer The question of interference is always a crapshoot. You would have to see if the transmitters are both on the same frequency and channel and none of that info is easy to find. I would say try it, and if you get interference, return it.
But I would not say "try it" because the Rocketfish wireless subwoofer kit you mentioned does not come with speaker level inputs, and the Samsung unit does not come with a line level subwoofer output. So the two systems are not compatible. To use another systems active subwoofer would still require either speaker level inputs on the subwoofer, or speaker level-to-line level converter between the Samsung and the subwoofer.
