The accuracy of CAL's steering enables system designers to provide directed coverage even when mounting options in a venue do not allow physically aiming the loudspeaker to the area where coverage is needed. Multiple or split beams can be used as needed to fit the application. For example, a split beam can be used to avoid sound hitting a reflective balcony surface.

Because CAL is oriented toward vocal reproduction, very high intelligibility was a requirement. reducing reverberation through pattern control is of little consequence if audiences still can't understand what's being said. Studies have shown that phase coherence at frequencies as high as 10 khz are important to intelligibility, in contrast to the long-held belief that bandwidth up to 4 khz was sufficient. CAL has been engineered to maintain accurate beam steering up to 10 khz to ensure greater intelligibility.

These MAPP Online Pro predictions show a CAL 96 with a split beam configuration to avoid placing energy on the balcony face while still covering all seats. The top portion of the beam is steered at a 17° uptilt, and the lower beam is steered at a 9° downtilt, to cover the main floor-level seating area.
