Founded in 1975, Jieli has become the world's largest audio company in terms of car subwoofer shipments, and won several first places in the first IASCA finals as early as 1989. With its abundance and deep diving, the Jet subwoofer has always been an indispensable musical companion for American consumers on the West Coast highway. In addition to the smooth low-frequency performance, excellent installation adaptability is also an important guarantee for its popularity. The interior space of the car is expensive, and the excessive volume occupation has always been a problem that the rear subwoofer cannot bypass. Jieli is targeted to adapt to 28 of the world's most commonly used car brands, hiding the subwoofer in all corners without reducing low-frequency energy, and maximizing the balance between audio quality and interior space. However, the promotion process of Jieli in the Chinese market is relatively weak, and the general distributor is located in Beijing, and the price ranges from 2,000 yuan to 20,000 yuan.
