Rythmik's are very musical and integrate well with the mains but depending on your room size, may not have enough weight/ punch. I had the E15hp.
I currently use seaton Submersive hp+ master and slave sub. It's every bit as good as Rythmik sealed subs but a lot more potent in output, specially mid bass.
