It may be inaudible, but I can tell you it shakes my rafters like no tomorrow with the 8X15s in IB. It adds to the movie for me. The house is literally crumbling on the right explosions. Then again that is between 10-15, mine won't effectively hit 5 even for rafter shake but pressure is still sensed.5Hz and 2Hz are most likely inaudible, so there really is no point reproducing them...
Sub Sonic Filter FTW!
I wouldn't expect you to understand the pleasure I get from it though, because it ain't no high falutin hi-fidelity setup //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
