Home audio playback generally used in homes, which is characterized by soft and delicate playback sound, appearance more beautiful `delicate, playback sound level is not too high, relatively few affordable power. Dance halls are generally used for professional speaker Kara OK hall `` `theater halls and stadiums, and other professional entertainment venues. Generally higher professional speaker sensitivity, playback high sound pressure, intensity, good endurance power, compared with home speakers, the sound quality is hard, appearance is also not very delicate. But in professional speakers in monitor speakers, and its performance is closer to home speakers, exterior generally more sophisticated `small, so these monitors are often home Hi-Fi sound system used.     2. Press the playback frequency divided: can be divided into full-band speakers' bass speakers and subwoofer. The so-called full-band speaker means to cover the low-mid and high frequency range `playback sound. Full-band speakers generally lower frequency 30Hz-60Hz, the upper limit frequency of 15KHz-20KHz. In most small and medium-Fi systems with only one or two pairs of speakers can be fully responsible for the full band playback tasks. Bass speakers and subwoofers are generally used to supplement the full-band speakers low and ultra-low frequency playback of special speakers. Such speakers generally used in large `medium-sized sound system, and efforts to strengthen a sense of shock of low frequency playback. When in use, mostly through an electronic crossover (crossover) after the division, the low-frequency signal into a dedicated bass amplifier, and then push the bass or subwoofer.     3. Purpose of points: Usually divided into the main playback speakers. Monitors and back to listen to speakers. Main speaker playback system is generally used as the main stereo speakers, bear the main playback tasks. Main speaker playback performance of great influence on the quality of the audio playback system, you can also use full-band speakers plus subwoofer combination playback.     Monitors for control room, studio monitor for program use, it has a little distortion, wide and flat frequency response, signal little modification and other characteristics, so most faithfully reproduce the original appearance of the program. Back to listen to speakers, also known as stage monitors, usually used in dance halls or stage for an actor or monitor their own band members sing or play sounds. This is because they are located on the main stage speakers placed behind the sound, you can not hear your own voice or the sound of the band playing, it is not a good fit or find the exact feeling, seriously affecting the performance results.

Press the box structure to points: can be divided into sealed enclosure, vented enclosure, labyrinth speaker, acoustic tube speaker and multi-cavity resonant speakers. Wherein the most frequently used professional speaker is vented enclosure, which features a wide frequency response, high efficiency, large sound pressure, in accordance with professional sound system speaker type, but because of its low efficiency, it is less professional speakers applications, mainly for home speakers, only a few monitors use a closed box structure. Sealed enclosure has a simple debugging, wide frequency response and good low-frequency transient characteristics of the design advantages, but higher on the dial sound unit requirements. Currently, a variety of speakers, vented enclosure and sealed enclosure occupied most proportion, structure form many other types of speakers, but rarely share.
