Some very good reading of the technical at a readable level.

| Listeners with hearing loss not only exhibit high judgment variability, they can also exhibit strong individualistic biases in their judgments. This comes as no surprise, since such individuals are really in search of a “prosthetic” loudspeaker that somehow compensates for their disability. Since the disabilities vary enormously, so do the biases. |
As these good white papers appear to be in the process of being removed from their servers to make space, I'll attempt to save them here so others may read them as well.

Loudspeakers and Rooms for Multichannel Audio Reproduction - Part I
How many loudspeakers? What kind? Where do we put them?
Here we look at the basic theory of multichannel audio systems, leading us to understand why certain loudspeaker designs and room arrangements work better than others.
Loudspeakers and Rooms for Multichannel Audio Reproduction - Part II
What makes a loudspeaker good? Can the same loudspeaker sound good in different rooms? What about “acoustical” treatment of rooms? Can I customize a room to suit my personal tastes?
Loudspeakers and rooms operate as a system. One cannot be separated from the other. Knowing this allows us to design better loudspeakers, ones that are ‘friendly’ to different rooms. Knowing something about room acoustics allows us to use furnishings and acoustical devices to improve stereo and multichannel reproduction, making the listening experience more pleasurable.

Perfecting the low frequencies. How many subwoofers? Where do I put them? Where do I sit? What about “bass traps”? How do I get rid of “room boom”?
Here we look at what it needed for truly excellent bass performance in rooms. An understanding of room modes, or resonances, is essential to achieving uniform bass over a listening area. The right kind of equalization can help to make that bass sound good, but it cannot do everything. Some traditional forms of equalization have a good chance of getting it wrong. Interestingly, two or more subwoofers, strategically located, can be very beneficial.
