If subbass is really non-directional I wonder if you could blindfold someone and have them tell if the L or R sub is playing while switching them back and forth....

You shouldnt be able to tell... [img]graemlins/dunno.gif[/img]

 

if you had your subs crossed over very high with a big difference in their position you would notice. but, for the same reason really low bass sounds like it comes from your windshield, stereo bass isn't exactly the most useful thing... the human ear can't detect the direction subbass comes from.

 

The only way you could tell, IMO, is if the woofer was playing over 300-400hz... (depending on the size of the woofer)

Other then that, I guess its possible that the woofers could load differently in relation to where you are sitting.... that could give them a slightly different freq. response...

 

hmm...all very good points made.
but if your in a car with some pretty powerful subs and you play the right sine sweep you can actally feel the bass hit it's peaks from one end of the car to the other as the frequencies max out at different points in the car. (actually i do this quit frequently when i'm giving demos to people, especially hot chicks - 9 times out of 10 a girl gets horny from the perfectly planned "sine sweep vibrations" [img]graemlins/thumb.gif[/img] )

come to think of it...i guess it might be more effective for me to realize my "moving bass" if it were over the front a rear stages. too bad subs aren't commonly installed in the front. another problem is that a lot of CD's are recorded in stereo and not 5.1 surround sound....ahh, that's when car audio will get REALLY fun - when CD's come recorded in surrround sound.

You should hear it coming from the center as that is where you would hear it in real life.

Subbass is non-directional - meaning it is very very hard to identify from which direction the sound originates.

Personally from what I have heard (i have tried stereo subwoofers in my house) there is no difference between stereo subs and subs stacked on top of each other in terms of imaging.

Output yes - big differences. Much better with the subs stacked.
