If your 6.5", 11 pound, 50W PC sub is problematic, I wouldn't expect any sub (sealed or not) that would be recommended here to work out regardless of where you position it.
For comparison, the Emotiva Ultra 10 is 10", 30pounds, and 200 Watts.
You can always turn it down, but unless there are regular times when you can crank it without worrying about the neighbors, I think you're paying money that will ultimately cause you frustration and resentment you're better off without.
Speaking of which, I don't know that rigidly mounting your speakers to the ceiling is the best plan either. 60Hz coupled to the ceiling is going to be heard in the room above.
You make excellent points here and definitely made my decisions a lot easier. Thank You.
Eliminating the option of a Sub and ceiling mounting the OMD-5's narrow my choices down so much. Without a Sub, it also basically eliminates the Bookshelf possibility. They simply (at least in my price range) can't handle the bass on their own so Towers are needed for my situation to handle the music/movies/games without the Sub.
I will be going with the Infinity P363's. Don't let me change my mind! lol They are simply the best option for me with my budget and living situation. They dig deep enough to alleviate the need for a Sub, they have unbelievable sound quality for the price, and they can be had for $350 Shipped. lol
My question now is what to do with the rest of the budget? I'm all about saving money but this is the money I saved for my sound system and nothing else. It's not that I'm determined to spend it all, but this is what it was delegated for so if I don't spend it here then I will just invest it into my "computer building fund" which isn't a high priority since I don't really plan on having it built until around Christmas.
I definitely don't want to just waste money either, though.
I found an Onkyo TX-SR508 for $199 Shipped brand new. That's $100-$125 Saved compared to my Denon and I believe the only thing I am losing is MultEQ which I have no use for without a Sub.
That leaves me around $450 in the Budget.
Should I go ahead and pick up the PC351 at least since it is like half price at $150 Shipped? I can't find much about it so I'm not sure what to do there.
The P153's are $140 Shipped which isn't a huge discount but still decent. Would those be great for the System or should I wait until I find a nice deal on the P163's?
My MAIN question is should I upgrade the Receiver? I'm scared to skimp on it since it is basically the brains and heart of the entire system. If I leave the Surrounds out for now, I would have around $450-$500 to spend on the Receiver IF IT WILL MAKE A NOTICEABLE DIFFERENCE.
Color GUI is not what I mean by a noticeable difference.
lol I mean if it will power the speakers better, sound better, have better video quality, etc. to a point where I'm like "man, I'm glad I spent that extra $200-$300 on this." haha
Thanks so much for the help! I promise you that I am getting close to having this finished. lol I just basically have to figure out the Receiver situation and Surrounds now (possibly the PC351 vs PC251 also) and I am done. The Fronts were definitely the hardest part and now that it's finished, the rest should be much easier.
*** EDIT ***
I just now noticed the "Thanks" feature so I'm sorry if I seemed unappreciative and selfish before this. haha I'm used to "Reps" but I didn't even see the Thanks. I'll try to backtrack and thank everyone for their help.
