Please recommend tutorial articles that recommend some basic starting-point room acoustic treatments, for stereo music reproduction. I'm thinking of basic approaches like the "live end / dead end" treatment; opposite-wall treatment to tame slap-echo; area rug placed to absorb first-order reflection from speaker to listening position; using furniture to absorb reflected energy; using bookshelves to diffuse reflected sound. Different viewpoints on "how much absorption is ideal". Just the basics, before one purchases the expensive room-tube treatments.

Here's a specific problem: I'd like to improve the acoustics in my kitchen, but there's not a lot of wall area available for treatment. I'd like to consider some creative approaches. For example: Highly effective ceiling treatments; highly effective panels for limited wall space (less than 10% of wall area).

All suggestions welcome!
