Coaxial speakers:one speaker has tweeter and bass, one top two. That is, two speakers are installed on the same axis, which are responsible for playback of high and low frequencies
Coaxial: All frequency signals from 20Hz to 20K Hz are transmitted to the listener's ear on the same axis;
Common point: All frequency signals from 20Hz to 20K Hz propagate outward at the same sounding point;
Common point coaxial: one point sound, synchronous transmission, positioning is odd
