1.it tampers with the arrival schedule of normal room reflections in ways that make it hard for your brain to get a clear fix on the listening-room layer.


2. the diffusor breaks up irritating slap and flutter echoes that often plague playback in domestic listening environments. These echoes---artifacts of reflective, parallel room surfaces---overlay the music that follows and obscure its inner details.

3.the diffusor tames comb-filter-type frequency colorations, previously addressed only by laboriously tweaking the physical position of the speakers relative to room boundaries. By decreasing the depth and increasing the density and irregularity of comb-filter notches, the diffusor makes optimum speaker placement decidedly less critical.

4. and potentially most remarkable benefit of diffusion is that the flooding of the listening room with diffuse sound fosters a sensation of complete envelopment or immersion in a musical event, as opposed to the disengaged puzzling over sonic minutiae that too often passes for the audiophile listening experience.

In sum, with adequate diffusion, you can theoretically get a small listening room to sound rather like a very good concert hall because, psychoacoustically, all the same basic ingredients are there: a large enough time gap between direct sound and first reflected spike; lack of slap and flutter echoes and comb-filter colorations characteristic of small rooms; and the envelopment that comes from a dense, smoothly decaying reverberation that permeates the whole room.
