The CHL series adopts DUS AUDIO's latest collaborative waveguide technology, successfully coupling radiation from multiple drivers into a horn, providing efficient performance of a single horn driver system with high sensitivity, efficient power transmission, excellent directional control, and an ideal foundation for truly modular linear arrays. This coaxial collaborative horn arrangement embeds high-frequency horns within larger horns, cleverly utilizing the entire front area of the box as the horn, maximizing horn size and improving directional control at lower frequencies (longer wavelengths). CHL-24 is a large, long-range three-way (with built-in passive divider for medium and high frequencies) line array speaker Due to the use of built-in passive frequency division mode in the mid to high frequency range, the user's usage cost is better reduced. The CHL-24 is equipped with two high-power 12 inch low-frequency units, capable of handling frequency ranges below 500Hz The mid to high frequency section consists of two high-efficiency 4-inch magnetic tiles and flat film pure mid-range units, combined with two 1.75-inch high-frequency magnetic tile compression drivers, coupled into a 90 ° horizontal and 10 ° (adjustable in units of 1 °) vertically covered collaborative waveguide horn, forming a collaborative waveguide module in the frequency range from 50Hz to 18kHz. The box is made of high-quality birch plywood, with a high-strength waterproof and wear-resistant polyurea coating on the surface. The front of the speaker is protected by a high-quality coated steel mesh combined with a breathable waterproof mesh. There are four ergonomic handrails on the outside of the box, and a three-point balanced hanging bracket is used to connect other products in the same series to achieve sound field positioning. The directionality of the sound field depends on the number and angle of speakers, and can be matched with the geometric shape of the audience. It is perfectly driven and protected by a proprietary power amplifier preset by a professional processor. The CHL-24 speaker has a maximum output sound pressure level of 146dB SPL, which can provide sufficient energy for audience areas within 150 meters, meeting the needs of large-scale mobile performances such as live rock music performances, EDM DJ music parties, variety shows, and large-scale corporate gatherings Due to its relatively compact size, CHL-24 can also achieve excellent sound effects for indoor facilities such as Live Houses, large dance clubs, auditoriums, and other main sound reinforcement systems.
