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.
