racedoc,
Main thing to keep in mind is the difference between adding "a subwoofer" and adding several. I've had "a" sub as has Tim and others, and what we're all saying is there's a huge difference when going to the multiple sub/distributed bass array/swarm type setup. Your speakers go pretty deep already, but the value we're talking about is a lot more than that. In other words even if you gained zero in terms of extension and headroom (you will, but assume not for now) then you would still notice a lot of improvement just in terms of the bass being a lot more articulate, musical and lifelike. Its just hard to appreciate until you hear it because listening to only one or two subs in a system that's all you really get, a little more extension, a little more volume. With 4 you open a whole new dimension.
In terms of ambience and soundscape, there's two very different ways people hear or perceive that. There's the higher frequencies where timing is so important and we all pretty well get that part. But the way we perceive and interpret low frequencies is quite different in that timing hardly even matters its the speed and smoothness of the bass that counts. Smoothness comes from more sources that create more modes, which equates to faster bass.
What I'm hearing, or better experiencing because of this, is less like more/deeper bass than more/deeper immersion in the recording. You just feel more "in" the space than in your room.
So to answer your question no, I don't think that "a" subwoofer will do much for you. But three or four? Yes. Definitely.
