none of what ? the speakers ? actually, thats what i am eluding to. seems to me, that the screen would throw light onto the cabinets, causing a distraction. i can see that effect in the pic you have posted.
i say "seems", as my speakers are not out enough to catch any light. and i have never tried them out. so i don't "know" what the effect would be.
anyway. great looking setup. i would love to see/hear it !
