Subwoofers down-firing or side-firing? Why?


Just added down-firing subs (Omega 10", sealed) to my Omega single driver speakers. I could ask Louis, but why do you think he designed them to be down-firing?  My prior REL and Rhythmiks were side-firing (used with very different systems).

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.
