The wavelength is therefore 1.2m, which means the frequency is 285Hz. Destructive interference means the reflected energy must be 180 degrees out of phase with the direct energy, so 0.6m equates to half the wavelength. The front panel of the monitor is around 0.3m away from the wall, so aВ reflection nominally results in aВ round trip 0.6m further than the direct path from monitor to listening position.

The second really notable feature is the sharp suckвЂ‘out just under 300Hz, and some quick calculations of path length suggest that this is down to reflections from the wall behind the monitor. ItвЂ™s also an effect in the room that IвЂ™m aware varies somewhat with listening position. This is probably caused by one of the primary standing waves in the room, perhaps aided and abetted by the destructive effect of the first sideвЂ‘wall reflections, and it ties in reasonably well with the sound that IвЂ™m subjectively used to. The first feature of note in the measured response is the big suckвЂ‘out around 70Hz. ScreenВ 3: The Systemwide application, showing the measured monitoring frequency response and the inverse correction curve. IвЂ™ll describe the function of the other options and adjustments Sonarworks makes available in the window aВ bit later, but first, aВ little analysis of the measured performance of my LS50s and room seems appropriate. The display shows the Sonarworks measured frequency response in blue, the correction curve in green and the predicted resulting frequency response in purple.
