M1500Ⅱ car speaker system is an upgraded version of the M1500, with the following features: The shape of the aluminum basin frame is redesigned, which is more modern, more concise and more stable. According to the special acoustic environment in the car, the frequency divider of the M1500Ⅱ car speaker system is re-optimized and adjusted to make the sound more in line with human hearing habits, making the mid-high frequency more round and clear, not easy to fatigue, and never tire of listening for a long time.
    
Bringing together Swans' very advanced electro-acoustic technology, excellent production materials and rigorous production technology, the Swans car audio family has added a new member - M series professional car speakers. M series products all use aviation aluminum-magnesium alloy diaphragms. The great advantage lies in its strong rigidity. Under the working conditions of large dynamic range, it still maintains low distortion, good high frequency response and strong detail resolution; it is very suitable for Set up a car 5.1 theater system, and reproduce the musical essence of rock music and pop music.
 
There are four models of M series products, center surround: MC-25, MC30; set series: M1500, M1600; the center and surround units are designed with 2.5-inch and 3-inch full-frequency speakers, aviation aluminum-magnesium alloy diaphragm, equipped with With high-recovery PU loops, it has very good stiffness and dynamic stability. High-power high-temperature resistant Kapton voice coil skeleton and high temperature resistant CCAW wire voice coil with no eddy current loss, high-performance NdFeB sandwich magnetic circuit provides powerful power for the output of high sound pressure. High adaptability engineering plastic, beautiful appearance.
The diaphragm material of the M series set speakers is also made of aviation aluminum-magnesium alloy. The material formula of the shock cone is readjusted to improve the overall specific elasticity rate, and the sound is clearer and smoother. Largely optimized high-performance magnetic circuit with low-distortion design, the mid-frequency performance is delicate and natural, and the bass effect is more powerful. After years of improvement and optimization of the tweeter unit BT28, the sound is more delicate and charming, transparent and fluent, clear and natural; the power carrying capacity is greatly improved, and the frequency range used is wider.


In the design of the crossover, the concept of Hi-End and our exploration and research on the restoration and positioning of the special environmental sound field of car audio in the past two years are combined. With a specially customized speaker unit, the sound image positioning, imaging power, and music performance have reached a very high level, and according to different car interiors (leather or cloth), it also provides accurate treble sensitivity adjustment, making it easier to use. convenient.
