With the small box body and high power mode, the front loaded horn inverted phase structure and six order band pass structure are adopted to give full play to the characteristics of the horn structure, greatly improving the system's sound pressure output capacity and the linear working range of the system
China Flower Expo Park is located in the east of Yuehai, the west of hydrophilic street, the north of yuehailanshan road and the south of Yuehai Huanhu Road, with a total planning area of 5300 Mu and a total investment of 1.5 billion yuan. The construction of Expo Park is based on "long-term, high standard construction", centering on the characteristics of "mountain, water, return to hometown", relying on the natural landscape background of Helan Mountain and Yuehai, combining with the requirements of the continuous construction and improvement of the park, and based on the central area of urban development, expanding and extending the green vein, improving the living environment.
GLS line array system full frequency linear array system is used in the sound reinforcement system of the park (la-210 and la-25 are used for fixed installation, and CLASSIC MC series are used for power amplifier)
Four seasons Pavilion
More than 40 sets of all-weather customized linear loudspeakers developed by our company have been shared in five areas, including flower expo park and four seasons Pavilion
Linear loudspeaker
Combined with the efforts of 19 years of Ge Lei Shi people, the developers applied advanced design concepts and according to the needs of the market customers, used the small box body high-power mode to adopt the front loaded horn inverted phase and six-step band pass structure, gave full play to the characteristics of the horn structure, greatly improved the system's sound pressure output capacity and the linear working range of the system, extended the sound energy projection distance, and comprehensively To improve the effect of super low frequency, it also benefits from the use of high-quality bass driver with high efficiency. It has a strong sense of low-frequency energy and amazing explosive power, excellent transient performance, strength and hearing resistance.
