It's basically about getting the speakers and listening chair(s) where they give the best/flattest/most even response in relation to EACH OTHER...nothing more.
The room is basically a pool filled with bass modes/waves. You ideally put your listening chair(s) where the bass is the most even/balanced, and then placing your speakers where it compliments the reponse from the seating possition...were talking ONLY bass response here.
You can start by placing the 802's woofers/port where your head will be(once you've disovered your seating), then play some bass steady music while you move around near where the speakers are to be located, finding the best spot for bass response. Ideally you do the same for the other speaker, in a symetrical fassion. If not, you balance as close as possible and find a "balance" between them, keeping soundstage in mind as well.
You may then play test tones up to 300 hz with a sound level meter, and see how it measures. Flat/even is what you want for best dynamic range, reponse, etc.
You may then interchange the speakers for the seating possition! They correspond to one another.
Basically, if you're not getting good response, you can measure your system with test tones, an write down your measurements. If, say, you have a hole at 80hz/63hz,50hz, whatever, then you simply play the test disc at that(those) tones, and measure around till you find the spot(s) where the room couples well at that frequencies)...then move the speakers there and compare.
It's basically a balancing act.
I garantee those speakers can make bass. You just don't either have your seat(s) or the speakers(or both) set up right in relation to each other. That's it.
Other variables would be if you have a big bass hole/suckout due to structure or large trap of some sort. This is rare on a large scale, and is likely just setup error.
