Not happy with my sub after I moved

[Mudfrog]

I recently moved and I went from loving my sub to hating it. I'm using a BIC F-12 and it was getting the job done without any issues at my old place. The odd part is that the old room was much much larger. The room itself was around 2,000 sq ft with 12 ft ceilings. It was in a carpeted basement. Since I moved it is in the main living room which is probably a 12x20 room with hardwood floors and 8 ft ceilings. I ran Audyssey and in order to set the sub to 75db like it instructs you to I had to put the subs volume knob to 1 (out of 10). Audyssey then set the sub to +1db. When I watch movies I can barely hear the sub at all, I can feel it shaking the floor under my feet but the sound coming from the sub is to low and it doesn't match the rest of the audio's volume. It kind of sounds hollow at times if that makes any sense.

I plan on upgrading to a better sub in the near future but for now I'd like to enjoy what I have. Should I ignore what Audyssey recommends and increase the sound until I'm happy with it? I mean I know I can do that but from a technical aspect is there a better solution?
