Flex Focus loudspeakers employ shaded line array technology with ribbon HF drivers to extend sound projection in longer meeting rooms. Their Frequency response (120-20,000 Hz ±3 dB) has been optimized for speech intelligibility. Flex Focus Vertical Arrays are available in two configurations. A standard version with loudspeakers oriented for monitors which are mounted at a normal viewing height and an LAC (Lowered Acoustic Center) version for monitors which are mounted above normal viewing height.
