What is the best subwoofer you have ever heard?

It depends also about your wishes and how you will use it? Is it for multi chanel or also for stereo use. Since today I did not hear a Rel or Velodyne demo were in stereo use the instruments still were very small and direct to point out. The EQ system of Velodyne solves the acoustic problems very well. But even at show's wenn I use my own music I never heard it 100% syngron with the speakers. These days I use the PLW-15 with my way of Audyssey pro measurment. It is the first time I have the stealth integration I was looking for.

Bo1972, I have always used my EARS to dial in my REL sub,it sounds very well integrated and does not muddy up my super fast main speakers (Dynaudio). The REL is very fast indeed and accurate.The REL allows my main speakers to be faster! And Its my EARS that tell me this Not some device. Not theres anything wrong with measurments but at the end of the day its YOU who has to like what your hearing. "If it sounds good, it is good". My quote of the day ..lol

I listen to music with my REL Britania series NOT helicopters and explosions, so my views are reflective of my 2 channel audio exp. The REL studio series are not good musical subs.They are meant for HT. I like a sub that has the woofer facing you for best musical sound. Not one thats pointed at the floor.

And IF any one post that SUBS are meant to be felt not heard is full of %$#@! because you have never heard a great sub then.

I am talking about use for home theater, not music. I am looking for a sub that has impressive visceral power and punch. Also, a sub that is fast, detailed, low and accurate. A sub that can pressurize a room without distortion. A sub that can be felt in the chest, not just the feet when planted on the floor. I am looking for substantial power as well as accuracy.

I am considering Paradigm Signature Sub 2. Would any owners like to comment on this product?
