Dipole? Monopole? Listening distance? EQ?

It also depends somehow on the signal as well. In some recordings there might be reverberation down to bass range which helps in this matter. I remember synthetic bass was the worse stuck inside the head all the time.

It might be "Envelopment and Small Room Acoustics". Look at bottom of page 9 and 10, where he mentions in-the-head localization.

Puppet, If the listener is inside the small circle then this is not the same at all what Markus was suggesting.

Yes, could be that, or one of the several of his papers which also mentions about this. I believe it is in his website.

Do you believe the mixer/master engineer intended the bass to be inside the head ?

Thanks David,

I recently moved to a place where sound transmission to the neighbors is much more important, so I actually have been reading in. However, as you already pointed out most information regarding sound isolation concerns speech frequencies, while bass frequencies are actually much more problematic.

What do you think about the multi-sub approach and sound-transmission to the neighbors? In comparison to a single sub, multiple subs in general radiate more sound power for a given level at the listening position, so you might say there will be more transmission. On the other hand the extra power is used to cancel modes.

Of course not and as I already said, I don't get in-head localization like you do. All I get is deep, clean, tight, fast, articulated, ultra-smooth bass - best signal modulation reproduction

Maybe you're running the sub too high? Or it produces too much noise/distortion.
Didn't you find the smoothness of the frequency response quite enjoyable?

Which part? I was always talking about the source being very close, like 2'.
