RE: Multiple, smaller tube traps...?

Bass traps are placed in corners because they are the location in which all bass modes are present. You get more effect from a bass trap in a corner location than anywhere else in the room.

Say the fundamental standing wave for a room dimension is 20 Hz. That room axis will also support standing waves at 40, 60, 80, 100 Hz and so on at 20 Hz intervals. All of those modes will have peaks in the corner and the bass trap will work to reduce all of those peaks if placed there. The corners are the only places where all of those modes are present in the one spot. Yes, you can find peaks for each of those modes elsewhere along the walls, and also in the centre of the room, but only some of those modes will be present at any location where there is a peak, not all of them. They aren't all distributed around the room in the same way. You can treat every location where there is a peak along a wall, but you'll end up with traps at 4 or 5 or more locations along the wall as well as in the corners, and none of those traps outside the corners will be as effective as the traps in the corners.

If you want more bass absorption, go floor to ceiling in every corner and make the traps bigger in every corner. You'll get more effect for fewer traps by treating the 4 locations where every room mode peaks in the one spot rather than treating a multitude of peak locations elsewhere in the room.
