CT304

Product type: 【CT Series】All-weather
Product Profile:The CT304 loudspeaker features four 3-inch full-range speaker drivers and one 3-inch passive radiator. Arranged in a curved array, the drivers are closely and vertically aligned, with each adjacent driver offset by a 4.5° vertical phase shift. A single loudspeaker forms a vertical 18-degree arc, while a two-loudspeaker array forms a 36-degree arc. Inspired by the widespread application of phased array radar technology, acoustic engineers developed "Constant Beamwidth Transducer" (CBT) sound reinforcement technology. The CT304 loudspeaker utilizes the CBT sound reinforcement concept, sacrificing the relative phase coupling effect of adjacent drivers (less than 5°) to a limited extent. Compared to traditional vertical column loudspeakers, it provides a more uniform sound field distribution in the surrounding environment, achieving uniform sound field coverage that is unaffected by frequency and distance.

Product details

Equipped with CBT (Constant Beamwidth Technology) phasing, it achieves uniform sound field coverage unaffected by frequency and distance.

Without DSP intervention, it effectively reduces comb filtering between adjacent units and minimizes drastic sound pressure variations in the near field, 

resulting in relatively consistent sound pressure across a larger area.

It lessens the impact of environmental factors on the sound field, allowing the loudspeaker to perform optimally in various environments.

Multiple units can be quickly connected to extend projection distance.

The sealed enclosure and specially waterproofed driver materials provide all-weather functionality.
