A crossover separates the high frequencies from the low frequencies, usually around 2000Hz, so you can send the highs to a tweeter or smaller speaker and the lows to a woofer. For some reason it sounds better that way than sending the full audio spectrum to both speakers.
It sends the correct frequencies, to the appropriate Drivers.
is a speaker made to be heard and loud

Sound energy is given out by a loud speaker. This energy is produced by the vibration of the speaker cone, which creates variations in air pressure that we perceive as sound.
there are none
Forward crossovers......
Because at very high frequencies, the inductive effect of loud speaker coil is so high that practically no current passes through it. Further, the diaphragm of the loud speaker cannot respond for such high frequency. Hence ultrasonic waves cannot be produced using loud speaker.
Figure it out yourself
