I wanted to give an update to this post, I ordered the towers and center from Dennis at Philharmonic Audio and I have to say I'm quite impressed. Dennis was great to deal with, he sent me the before and after frequency responses, and for the money I'm not sure there are any better options out there. Comparing them to the stock Pioneer monitors I got (I know it's not a very fair comparison), they sound much better. My problem right now is getting the lip sync matched up, my receiver has a setting that you can adjust the audio delay, but I need to delay the video... trying to figure out how to make that happen.
@Zeiglj01, thanks for pointing me to Dennis, I'm quite pleased. He built the towers and center for me and had them shipped within a week, He screwed up the billing and accidentally charged me for his Philharmonic 3's, I was very tempted to tell him to keep the money and send those instead. I already made an enemy of my wife for a few days with the cheap ones (she doesn't understand why we need more speakers when the TV has it's own), so that really would have made her mad. Maybe later on I will be contacting him again to upgrade.
I haven't gotten a sub yet, but I'm leaning towards a DIY. I'm still in the research phase, but ITS has an 18" sub, the model of it looks a lot better than anything else I could buy in the price range. There are lots of builds with that sub so it would be easy to just copy one that worked well. also, from what I'm seeing most amps comes in at least 2 channel for subs. When I start feeling the upgrade-itis itch again it will be easy to add another sub for cheap.
