How about the doctor's stereo?

Dr. Audio has a patent for a direct reflection loudspeaker 91. If you want to create the effect of that kind of concert hall instead of effector equipment, Dr. Audio is a good choice; Doctor Audio has the world's smallest "treasure chest" speaker, which was developed in 1995. The "special formula" diaphragm material and NdFeB strong magnet unit make this small combination not only occupy no space, but also make the stereo effect more perfect. Doctor Audio Leisure 35 Series is the only intelligent home theater series in the world. Let even the "layman" who doesn't understand the sound theory spend only 1 minutes to automatically adjust the sound effect to the best in the room.
