My take on Fullness is this:
When you sit up close, within 20-40'
the L1 systems sounds the "fullest".
As you move to the back of the club, the bass frequencies drop off,
however, the overall sound still seems well balanced, just "thinner".
To me this sounds like a pair of open ear headphones with a walkman
...crisp, but not heavy on bass.
It's not a bad sound though, to me it is pleasant and natural,
clean and clear rather than boomy or muddy at a distance.
I find the best visual example is a videotaping I made
of Bose user, Baby-Blue-Eyes's "Sinatra" band.
My wife taped them from the rear of a large tent,
even taping with the camera pointed away from the band.
The sound is smooth and consistent.
Then she walked forward to the band, and you can hear the changes.
At about 40' out, the bass quite suddenly becomes more apparent.This Video Clip
should give you a good idea of near/far sound perceptions with the L1 system.
Bear in mind the video cam is not the quality of the live sound
but gives a pretty clear interpretation of the "difference" to be heard.
That day, the other bands all played thru the bigger system you see.
When I was at the back of the tent,
I found their sounds to be quite less "natural".
It was somewhat fuller, but at the expense of the clarity.
I hope this is of a help to you, and that the filesize is
not too large for your downloading capabilities over there.
***BTW, I saw a NEXO line array at a Bebo Norman concert in St Louis last year.
Until today, I didn't know who made that system, but I remember that logo.
I was astounded at the sound, NEVER had I heard that good a sound
in a concert PA system (in a really big church). And NOT TOO LOUD!!
I remember searching the web for pictures to identify it,
and asking around the forums about it, trying to describe their wishbone shaped logo.
My wife and I talked for months about how good the sound was.
NOT PAINFUL, even as close as we were sitting, about 5th row,
right in front of the line array and it was very comfortable.
No earplugs...which is odd for me at a big concert.
I would liken the Bose L1 sound to one of these systems, only not so loud of course.
I was a Bose user at that time and was spoiled on the sound and was avoiding concerts
because the sound was usually too loud and too unclear for my new tastes.
But the Nexo was very, very nice.
