A:
I used these speakers to present a homemade Halloween video to my son's 5th grade class of 30 students plus parents. Even though we had to place the speakers on the floor, the sound was crystal clear and loud enough to hear the crickets that had been chirping in the background when the video was being made--I was very impressed. I believe these speakers would work well in a presentation setting with 30 to 40 individuals. Particularly if the speakers can be placed off the floor.
