Abstract
A driver arrangement for a speaker array (201) comprises a first and second driver (301, 303) each arranged with an on-axis direction at an angle to an on-axis direction of the speaker array (201). The first driver angle exceeds 5° and the second driver angle exceeds the first angle. A front section of each driver (301, 303) comprises a front edge of a radiating element and parts of the driver in front thereof. The drivers (301, 303) are arranged at least partly inline such that a first distance from a front axis (311) perpendicular to an on-axis of the speaker array (201), and intersecting a furthest forwards part of the first driver front section, to a closest part of the second driver front section is lower than a second distance from the front axis (311) to a furthest part of the first driver front section. The combination of angled drivers and the inline arrangement provides improved performance.
