The adoption of Class D digital power amplifier and 20W high-efficiency speaker design makes the output sensitivity up to 92dB.
The speaker built-in echo tube design presents stereo sound in bass to make people immersed in the high quality surround atmosphere and endless auditory feast.
High/low pitch optimization design, enhancing the response frequency in 50Hz and 20KHz range, regardless of high/low pitch sound quality is clearly distinguishable allowing teachers and students to interact under the pleasant sound.
The speakers installed at the front of the classroom are in a dilemma that they can be heard clearly at front but blurred in the back. The unique patented installation design of the CH-20 is easy to install in the center ceiling of the classroom creating a surround sound effect allowing the clearest and best sound quality in all space.
CH-20 Hi-Fi speaker allows teaching and presentations to clear sound quality. It can be used with flat panel displays or projectors to create the smart classroom.
