  32. The price of "The Listening Room" is about $45. If you want to learn more
  33. about speaker placement, you might like to check out old issues of the
  34. Journal of the Audio Engineering Society. They had an article or two that
  35. presented formulae for computing the effects of room boundaries on
  36. speaker response.
