Subwoofers down-firing or side-firing? Why?

I've tried both configurations with the exact same subwoofer.  With downfire, you do hear the bass, but you don't get nearly as much "punch you in the chest" type of sonic impact.

The Sub-x sub from Golden Ear has too side firing active drivers and a top and bottom firing passive radiator. Its much easier to get the placement right.

"....Downfiring subs allow the bass wave to move in several directions in the room at once. The problem you have with bass in a room is standing waves which can cause cancellation at some places in the room and re-enforcement in other places. By having the bass radiate in several directions at once, its easier to place the sub or subs so you can get more uniform bass because some of the standing waves can be less pronounced...."

I believe that is Rel's position on the matter, making for easier integration.  

sub woofers are only meant for HT, sound effects, and parties/HIP HOP/rapp, 
But never ever for real music. 
There is no such thing as a  <<high fidelity subwoofer>>>
a  sub is only for sound efgects = anti musical.
Just thought I'd make this clear.

You are correct it is "High fidelity subwoofer" there are no <<<< or >>>>.

GR research servo bass system, is about as high fidelity as you can get.
Mozartfan? Nothing below 60 hz is considered part of music.
HIP HOP / rapp isn't real music. OK you say so...

"I like big butts and I cannot lie", remember that song? I do, it's music of the most delicious kind... Yea...
