I recently moved into a larger home, my last HT room had 12x10 walls with 8' ceiling. I had a cheap 8" sub with 100w that came with a HTiB, it shook enough, forgetting that the quality was just trash. Now, I've noticed that it almost appears that my sub is not even working in the new home. The floors are laminate, the living room connects to the kitchen and dining and is pretty much open. There is a 4 1/2' wall separating the living / dining and it is open above that, in the kitchen there is a bar that stands 5' high and the other half goes all the way to the ceiling. The dimensions for this entire area is 30' x 24' x 10'. The 30' wall is divided by the separator I spoke of, it is 16' from the living room wall to that wall. So to that wall the room is 16 x 24 x 10 (But I included the above detail for more accuracy).
There may be standing waves, or the volume of the room is just so much that the sub just doesn't put out enough. It turns on, it does make sounds and some vibration, however, in the last room I would have it turned to 11o'clock and it would sometimes be too much bass (not for me but others)(on a 7oclock to 5oclock scale). Now I have it at like 3-4oclock and it makes no difference from 11-4oclock the sub seems to put out the same. I opened it up and checked fuses, none were blown. I think the room size has played with my head cause I was thinking the sub just went bad.
Anyways, I've been reading these forums for a while now, looking at budget subs etc. I was first going to purchase 1 budget sub ~250-300, but now I'm thinking that it wont be enough. I was thinking of raising my budget to be 400-450 and either getting a better quality sub or 2 budget subs.
My number 1 choice for budget sub right now is the PL-200, based purely on research. I also like what the PA-150 seems to offer. I noticed the HSU-STF2 is on sale right now too. After more and more digging I started to think that maybe because of my layout I'm going to have serious issues feeling/hearing base in my seating positions. So then I was thinking of maybe a higher quality sub closer to $500? I also thought about getting 2 HD-Sub12's for $400 total, although I've only seen very few reviews info on those particular subs, I cannot go over $500 shipped though, that is the absolute max.
Any and all input is welcome. I'm trying to attach a sketch of my living room.

I wonder where the best position for my sub is, I tried doing crawl with my crappy 50w RMS 100w peak Yamaha but it makes almost no difference (I think because of the shear size of the room I'm trying to fill). I don't know how the wall that divides living room and dining room effects the sub, is that corner ideal or the one where it actually is a full wall like the corner top right of the room? How does a sub reflect with Open walls like that? Thanks!
I almost forgot to mention this is 100% HT usage, if any music is played at all it will be usually through a TV channel and quality is of little importance, we want the best HT experience we can get out of our budget.
