Hey guys, I have a question regarding my subwoofer and placement. The sub is a Martin Logan Abyss. It can either be downward firing or forward firing. Right now it's in a corner and downward firing. I recently mounted my TV and have an empty space below the tv along with a blank wall plate covering the existing coax and ethernet jack. I was thinking of placing the sub infront of the jack so it will cover it and break up the "emptiness". Picture below for reference.
I have a Radio shack digital SPL meter and have the sub and all speakers set to 72db. If I put the sub in the center below the tv and set it up to fire forward, won't the SPL meter show the same db rating even if I hear "less" bass by ear? I know that sounds confusing, but it's the best way I could explain it. Does anyone run a forward firing sub directly infront of their seating area? Also, will I benefit by setting it up as forward firing if centered, or should I keep it downard firing..I really don't know the advantages or dissadvantges of each. Any help is appreciated.
Thanks
