All of these issues become important and the combination is just too demanding of the number of measurements to get timely and valuable data. These include, on-axis, off-axis, centered, off center, with and without subs, different distances between subs/LF drivers, crossover slopes, etc. Multiple speakers are not considered since there are so many combinations of issues that could be measured.

These issues include the repeatability of the data, effects of microphone position, the effects of the room and a comparison to an FFT based analysis program. Data is collected to explore several issues through the measurements. The purpose of this paper is to provide comparative acoustic measurements between SmaartLive, and the real time analysis (RTA) and auto-EQ functions of the DriveRack 260 (DR260) under various conditions.
