front firing has always sounded better to my ears and room. martin logan? i owned some for a while. sounded best projecting into the room.
Sub questions
I have a sub (soon to be 2) that has the option of front firing or down firing. When I got it, it was already set up for down and I never bothered to try front. Does anyone have a strong opinion either way?
Also....the floors in my house are all ceramic tile. If I keep them down firing, would I benefit from putting small rugs under them?
If it matter, subs are run at very low volume and crossed around 60 hz (still dialing things in in a new room and with a new amp).
What say you?
