EF series of three products: EF10, EF12, EF15
Customized high-frequency compression unit, the sound membrane material is specially treated, the tone is delicate and soft
Ultra-long voice coil design provides a stable linear magnetic field force, providing more stable sound under large dynamics
Low-distortion fiberglass horn reduces sound coloration and provides self-heating and realistic sound
Specially treated diaphragm material improves the transparency of the mid-frequency and makes the low frequency fuller and more powerful
Precisely designed crossover network, using low-distortion components, optimizes the clarity and intelligibility of the human voice
The box size is repeatedly optimized and debugged, with excellent acoustic characteristics
Using environmentally friendly water-based paint, increasing elastic components, delicate feel
Suitable for performances, restaurants,conferences, hotel banquet halls, auditoriums, multi-function halls and other high-demand amplification venues.
P.D loudspeaker the newly developed EF series passive professional entertainment speaker system is used in chain KTVs, nightclubs, clubs and other fixed installation places that require high-quality sound. This series of products is specially developed and designed based on the psychological and physiological hearing of Asians, highlighting the vocal part, with a thick and full low frequency, and is easy to sing and listen to. Low distortion, low-power compression speaker unit improves heat dissipation efficiency and reduces power compression under high sound pressure. Specially treated diaphragm materials improve mid-frequency transparency and make the low frequency fuller and more powerful;
The EF series audio cabinet material uses multi-layer high-quality birch plywood to make the cabinet, with a concave and convex complementary structure design, CNC processing, and high-strength glue connected to form an ideal rigid cavity. The cabinet size is repeatedly optimized and debugged, with excellent acoustic characteristics. The full-range speaker is equipped with multiple M10 hanging points to provide a variety of hanging methods for fixed installation places.
