Different frequency speakers
Low-frequency loudspeakers: usually withstand nearly 90% of the power in the entire system. The current flowing through the voice coil is large, and the vibration amplitude of the cone is large. The cone cone material of low-frequency speakers is usually made of paper cones, as well as graphite reinforced polypropylene cones, carbon fiber braided basins, glass fiber braided basins, bulletproof cloth basins and wool basins.
Mid--frequency speaker: It is the key unit of the entire speaker. Generally, there are two types of mid-frequency speakers: paper cone and dome. The dome type can be divided into a soft top and a hard top. The soft top is generally made of hot-pressed cloth-based material specially impregnated with phenolic resin. Its tone is more delicate. Hard dome is usually stamped with titanium film or aluminum film, and its sound is relatively crisp.
