This paper compares two different types of floor-standing loudspeaker systems. Both were measured over an acoustically reflective hard surface in a large space. The first is a high-performance conventional three-way 12”-woofer studio monitor and the second is a ground-plane circular-arc CBT line array loudspeaker. Measurements included direct-field frequency responses in front of the systems at 20 grid locations ranging over different distances/heights and response vs. distance at seated and standing heights. Horizontal off-axis and near-field responses were also gathered along with ceiling illumination responses at several launch angles. The measurements reveal that the CBT system has vastly more even coverage at all these locations compared to the three-way monitor and in addition eliminates the detrimental effects of floor bounce.
