I've got this sub as my first subwoofer in addition to T7Vs. I mainly play techno so let me tell you, the sound is chunky, fruity, aloud and if the monitors don't fulfil the spheric loudness in the room you can always let in a bigger frequency range on the sub pushing crossover to 120. However the punchiness comes and stays only at 80, at 120 you get this underwater bass, which is still great for all the sweeps, beeps, clicks and zaps in the tracks. Really enhances the frequencies left over from monitors for sure. Once we get to about 96db with crossover on 80 the big Adam brother unleashes it's power, everything that's below 10g starts sliding in the room and behind my neighbours wall, at this volume I've got numerous complaints and got reported to city council for being noisy.
All in all, as my first 2.1 system this exceeds any expectations that I had. Really feels like club even though I'm in my living room. Can agree with other comment saying that it gives you another perspective on how to mix your lows.
P.S. 'UPS' LOST HALF OF MY PACKAGE, AVOID NO MATTER THE COST.
