OK, I dialed it in and it sounds pretty nice for now. I ended up leaving the frequency where it is because when my brother came over to visit, he couldn't find the sub anywhere...lol. All he heard was bass. Then, I jacked up the volume and it was seriously mind boggling. The thing is, even at low volume, it's significantly better than the older PA-120. A huge difference in the musicality of the bass.
With the old sub, it seemed like there was only one "tone" for the bass. Now, I see that there are different frequencies of bass in a single beat or strum of a bass guitar. With movies, it's really nice and for the first time, I feel the clean bass in my chest. The entire couch shakes on certain movies. Now, I have to get all my favorite blu ray movies through netflix. It's times like this that I regret not having nice movies laying around. I tend to not buy much media. PS: Dolby digital on a blu ray sounds soooo much better than the same movie on cable.
Here is a quick and dirty pic of the sub in the corner. It seems like a perfect fit. I wonder if it's too close to the wall or the couch. Looks like about 4 inches between the driver and the couch and 4 inches from the kitchen island and 6 inches from the wall. The ports face out into the room.
The rest of my gear is as follows:
TV: Samsung 40" 7000 Series
Receiver: Pioneer Elite VSX90TXV
Center: Paradigm CC390
Front: Paradigm Mini MK3
Surround: Paradigm Atom V.2
Subwoofer: Premier Acoustic PA 120
I'll get closer pics afterwards.
