Blade he does well, he plays precisely even with fast beats (also 160bpm Darkpsy is not a problem) and really quite deep down. the kick bass is hammer, comes very crisp! However, I doubt that he plays 18Hz at -3dB. Sounds subjectively much quieter. Can also be due to my hearing. Too bad I still find that you can not regulate continuously the phase. Therefore, there was only 4/5 stars. Overall, I am but still very pleased with my purchase. Rest assured that your visit goes down the jaw if you romp the Sub times let =) To room size: In my stands in nem 10m² little room, but this is not a problem. On the contrary, in the room there since the sub in there is often times a very ordinary gravure printing and with room modes I've only one unrelevanten spot problems.
