I used DRA Labs’ MLSSA system, a calibrated DPA 4006 microphone, and an Earthworks microphone preamplifier to measure the T+A Solitaire S 530’s quasi-anechoic frequency- and time-domain behavior in the farfield. The center of the line-source tweeter is just 32" from the floor, but as the loudspeaker on its feet is slightly tilted back, I examined the farfield behavior on an axis at right angles to the front baffle with the microphone aimed at the center of the tweeter. The grille was left off for these measurements.
When measuring a loudspeaker’s farfield response, the microphone should be at least as far away as the drivers’ vertical dimension. Otherwise, the low frequencies will be boosted due to the nearfield
