So is the pb1000 not the way to go, are is the klipsch rw-12d, pa-150, rhythmic or Hsu? I'm lost. Lol, you guys really know your stuff that's why I'm asking yall because I'm fairly new to all this. I'm surely learning a lot from all this! LOL
It depends on what you are after. Each sub has its strength, although the lower cost subs have certain compromises.
The Klipsch will dig down to the 20s and should get pretty loud above the 30 hz range. It's bass might not be quite as tight as the Hsu, SVS, or Outlaw sub, but it won't sound bad. It is generally regarded as the best bang for the buck at anywhere near it's price, especially when it's on sale, like it is right now.
The SVS PB1000 might have better sound quality, and it will have deeper extension. I don't believe it will have the dynamic range of the Klipsch sub, especially above 30 hz. In other words it will sound more consistent and controlled, it just won't get as loud. The same is going to hold true for Hsu's 10" subs, the STF2 and VTF1, high quality bass but not real loud bass.
The PA-150 gets enormously loud above 40 hz, but not so much under that, so its not great for deep bass, but pretty good in mid bass, and it will stomp on all these other subs in upper bass. It's 60 hz + bass actually bests the SVS PB13 Ultra, SVS's $2k flagship sub. A good case could be made for this sub on the fact that most recorded bass is in mid to upper bass ranges. I don't know how it fares with respect to sound quality.
The Hsu, Rythmik, and Outlaw $600 subs, respectively the VTF2, FV12r, and LFM-1 Plus, have very good deep bass extension, very good output across the entire bass range, and great sound quality as well. The catch is they are a bit more expensive and larger than the others.
It sounds like the PA-150, and the larger Hsu, Rythmik and Outlaw subs might be a no-go for you because of their size, they are big'uns.
