Just thought I would put my thoughts out there since I just got my pa-120 blk in this morning.
I have to say I was struggling between getting a ed-300, aa12, pa-120, dayton, and others. I just couldnt see myself spending 300+ on a new sub to replace my psw10 so I started looking at some of the "budget" models to fill my needs.
I have to say, after getting the pa-120 and putting it through a couple of scenes from TDK, I have to say wow. I havent really even tuned it yet, just set the crossover,phase, and volume, but all I can say is wow. I took the suggestion and shrunk my room by 25% and then put the sub in that corner spot, several feet away from the corner in my room.
Comparing the psw10 and the pa-120 is like comparing an m80 vs a firecracker. Im not saying the pa-120 is the end all be all but compared to that polk, it blew me away. Every bass signal gave me a quick bump in the chest, the boomyness that was there is now gone, and base just sounds soooooo much smoother across the board.
Eventually I will try and run dual subs, move the polk to the front of the room to smooth out the front soundstage, but for now I am just enjoying it! Looking forward to watching Valkyrie tonight!
As a side note; there were some people that were not happy getting thier subs and seeing dings or scratches on the laquere finish. I have to say it looks like they took heed of your complaints. I opened it up, box was fine, they put a large clear sticker over the top to protect it from scratches. I was suprised when I opened the box to still be able to smell that fresh wood stain, sub was fresh off the production line =)
All I can say is that I am very happy with this sub. If you are debating getting it, just get it, for the money you wont be happier.
