how much of the LF on your front channels is directional?

how much of the bass on your front channels is directional?

there is this new piece of equipment, for the couch vibrators i have. it is a preamp sort of thing, that can input 3 channels(sub,left and right front) and output 2 channels(left and right couch shaker), with a filter adjustable from 20-500hz

its supposed to let your couch have stereo vibrations, but how much bass is directional on the speakers.

its a quality company, and their shakers won av product of the year 2004, so im sure it's going to be cool regardless, but how well do you think the stereo vibrations will be noticed.

I'd say cross them over at about 100Hz. But to answer you're subject question, THX says it's 80Hz and below that's non directional, but I say when the distance between peaks of the wave become longer than the distance between your ears (~100Hz I think) the sound becomes directional.

so does that mean that once a frequency reaches 80-100 or below, they will be at the same volume on both front speakers? ..since you couldnt tell where it was coming from anyway

Just because a sound is non directional dosen't mean it's not in stereo. most of the time, yes, LF is mono, but not all the time.

That being said, there are many other things that lend to a sound being directional, distortion being #1. Amplitude being #2
