No Problem. I heard this sub in 2 rooms, one was approx 13x20 the other was 16x25. I auditioned this sub against the Servo-15 and the PW2200. I actually picked the PW2200 at the time as money was the deciding factor. I can honestly say that the Seismic was pretty close to the mighty Servo except when going REALLY low. The seismic had no problems delivering earth shaking vibs even at very high volumes. I'm already planning on "upgrading again" to either the seismic or Servo in about 5 months (The seismic has high WAF value!)
I do have a question - Are you looking at this sub due size restrictions in your environment? If your are, it's a no brainer!!
