This article is unnecessarily complex, and offers solutions that are (mostly) applicable to older speakers. Most modern studio monitors put the tweeter in a waveguide. By doing that, it accomplishes two things: * The loudspeaker frequency response is consistent, no matter whether you're standing directly in front of the speaker, or to the sides. IE, the placement of the loudspeaker is less important than with older designs. * Most importantly, a waveguide takes the energy radiated by the driver and it focuses it into a narrower beam than a conventional tweeter. By doing this, reflections off of the sidewalls, ceiling and floor are less of an issue. To make a long story short, modern studio monitors with a waveguide are less fussy about placement. Reflections off of the sidewalls, ceilings and floor can still cause issues with lower midrange and midbass response, but these issues can be fixed with EQ to a large extent. The reason that EQ is less effective at high frequencies is because the wavelengths are so short. For instance, 5khz is 6.8cm long. Because it's so short, equalizing that frequency for one point in the room can screw it up at ANOTHER point in the room. Low frequencies are much longer, and because they're longer, EQ is more effective. For instance, 500Hz is 68cm long. Because of this long length, if you EQ a speaker to flatten out a peak at 500Hz, that EQ will be effective over a broad range of positions in the room.
