Frequently Asked Questions

Ar-Q optimizes the frequency response to match the speaker configuration, preventing muddiness and ensuring a balanced sound regardless of array size – crucial for varying venue dimensions.
While designed for relatively level surfaces, the stability relies on proper setup and the use of the recommended frame; extreme slopes require additional stabilization.
QSC offers a competitive sound with a slightly more focused, direct sound than some competitors; it's exceptionally versatile, though flagship systems from L-Acoustics or d&b audiotechnik might offer marginally higher SPL in extreme situations.
