Even more telling is the consistent intensity across the frequency band. What is most puzzling is the regular periodicity. | |

The listening area is heavily carpeted everywhere. The ceiling is canted with the right wall at 7 feet high and the left at 15. There is a double doorway on the left that opens to another room so no reflections can come from this wall. The microphone is at the height of the tweeters. The combing pattern also occurs when I move the microphone to the left. If reflections were an issue, the asymmetry of the room would prevent the symmetrical appearance of the combing pattern. | |
