WOW!!! I can honestly say I have once again gone way over the top....I got the PB-12/2 Plus in Rosewood (btw, the wood plus's do come with a paramtric equalizer same as the Ultra's - the manuals have not been updated so you need to print out an Ultra manual to set the equalizer - I have diabled it for now. The Plus in the black box does not come with the equalizer). I got the sub on Friday afternoon.....Saturday night getting ready to go out and listening to digital music channels on Time Warner cable and the door bell rang. It was the neighbor. Note, I live in a new freestanding house with alleys on either side and a firewall in the one side wall....There is about 6 feet between my wall and the neighbors..the neighbor said that it was like thunder going off in her house. Note, I had the bass up way higher than you would normally listen to it, so I toned it down a bit. When watching Matrix, the my wood floor on the second floor literally felt like it was buckling...I had to take apart my gas fireplace and tighten all the bolts and put small felt discs between two pieces of aluminum that would rattle. Watch the scene where NEO is in the helicopter and using the machine gun to free Morphius and it feels like there is an earthquake and sounds awesome. The scene where Neo and Morphius are fighting feels like someone is being slammed down on your floor everytime Neo gets thrown down. Two thumbs up, but I probably should have just got the 12 Plus...no need to two 12's except for showing off when a friend comes over......
