ST 43 is designed for applications to project vocal frequencies of the most subtle sounds throughout the venue. With a narrow vertical dispersion of 20 degrees, it is ideal for use in reverberant venues. The cabinet features a 4 x 3″ (75 mm) driver in a rigid, uniquely-styled extruded aluminum enclosure with a dedicated omni-directional mounting bracket. It has no parallel walls, which helps to eliminate all cabinet resonances. Additionally, its broad horizontal and narrow vertical coverage contribute to reduced reflection from the ceiling and floor in highly reverberant venues.
The ST 43 delivers consistent audience coverage with excellent accuracy and projection. The curved shape of the enclosure allows it to be surface-mounted close to walls and facilitates ceiling installation by using an omni-directional bracket, which maintains the dispersion pattern at all frequencies. An amplifier module powering the ST 43 is within the CR 210s subwoofer cabinet housing. The visually-distinctive enclosure can only be used in a vertical orientation and is available in an attractive matte finish.
