Ok i have been doing some testing on the sub and now i am a bit confused. I am upgrading from a velodyne vx-10. I played some parts from Kungfu Panda. I played the begining scene and the "skidoosh" scene. Ok now with the vx-10 the skidoosh scene had bass to it. When i played that scene on the phase tech it was alot quieter. My wife was like what happened, she said it was a dud. I played the same scene on a Element 12 inch sub from CC a few weeks ago and it shook the couch. Now the opening fight scene sounded great on the phase tech. I think i might have a input problem and need to play with some settings. Also another thing i noticed was when playing PS3 the sub shut down. I looked at the amp and the light was still on but no sound, wonder if it isn't getting enough signal. I have the level at +3. The amp felt hot. I lowered the signal down to +2.5 and set the sub volume to 11 position. I really need to get the user manual. I have the receiver set to "small" and the x-over set to 80. I had the sub set to 100 on the x=over but it sounds better setting it to match at 80. I will play around some more with it.
