Sidebar 3: In-Room Measurements
The following measurements were made at a single mike position at ear height (for a seated listener) using the OmniMic measurement system from Parts Express. Averaging multiple readings around the listening position has not been shown to offer more revealing results in my room than a single reading point, apart from smoothing out some minor ripples in the graph. All the graphs here were smoothed to 1/6th octave. While these results will not be as precise as those made with the tools used for our full suite of measurements (which dial out the effects of the room), they do provide a useful look into how the Monitor Audios performed in my listening space. All rooms act as a crude equalizer on the sound of any system, and the result will vary both from room to room as with regard to speaker positioning.—Thomas J. Norton
