一、报告厅音响需要经过一段时间的使用后，方能发挥出它的优良性能，这就是所谓的&濒诲辩耻辞;煲&谤诲辩耻辞;。否则，它的重放声音会显得偏硬和过分明亮，或发紧放不开，这个时间过程对不同的音箱可以相差极巨，从数十小时数十天不等。
1、 The speaker in the lecture hall needs to be used for a period of time before it can give full play to its excellent performance, which is the so-called "pot". Otherwise, its playback sound will appear too hard and too bright, or it can't be opened tightly. This time process can vary greatly for different speakers, ranging from tens of hours to tens of days.
二、小型书架报告厅音响由于受物理因素的限制，它的低音动态范围不可能太大，所以即使它的低频延伸得很低，其现实意义也并不大，可见追求小型音箱的低频下限，实际效果恐难理想，更不适合爆棚音乐的重播。
2、 Due to the limitation of physical factors, the bass dynamic range of the small bookshelf lecture hall sound can not be too large, so even if its low frequency extends very low, its practical significance is not great. It can be seen that the actual effect is difficult to be ideal when pursuing the low frequency lower limit of small speakers, and it is not suitable for the replay of burst music.
叁、报告厅音响的标称阻抗常见的有4&翱尘别驳补;和8&翱尘别驳补;两种，4&翱尘别驳补;阻抗的音箱，虽说能使功率放大器输出更大功率，但由于阻抗较低时，对功率放大器的输出电流能力要求高，这对一些电源裕量不大的功率放大器往往造成失真增大，而且低阻抗扬声器对阻尼不利，会影响低频控制力。此外某些扬声器的阻抗在实际工作时，于某些频率可能降低一半值以下，所以还是选阻抗为8&翱尘别驳补;的音箱。(例如，不少础痴放大器的负载阻抗就不能低于6&翱尘别驳补;)
3、 There are two common nominal impedances of speakers in the lecture hall: 4 Ω and 8 Ω. Although the speaker with 4 Ω impedance can make the power amplifier output more power, when the impedance is low, it requires high output current capacity of the power amplifier, which often increases the distortion of some power amplifiers with small power margin, and the low impedance speaker is unfavorable to damping, Will affect the low-frequency control force. In addition, the impedance of some speakers may be reduced to less than half at some frequencies during actual operation, so it is best to choose a speaker with an impedance of 8 Ω. (for example, the load impedance of many AV amplifiers cannot be lower than 6 Ω)
四、小口径扬声器单元的报告厅音响虽可以取得非常好的听音效果，但这种音箱只适用于近距离聆听。对于较大空间的房间，譬如厅堂放声，应选择采用较大口径扬声器单元的大音箱，才能取得好的听音效果。
4、 Although the speaker in the lecture hall with small caliber speaker unit can achieve very good listening effect, this speaker is only suitable for close listening. For rooms with large space, such as auditorium sound, large speakers with large diameter speaker units should be selected to achieve good listening effect.
五、哑铃式报告厅音响采用两只相同的中低频扬声器单元，在高频单元两边作对称布局，能取得较好的低频和瞬态响应、较高的灵敏度和功率承受能力，大动态非线性失真较小，但它的中频段综合频率特性往往产生低谷，而且垂直方向性窄，所以它的中音性能应予注意。不过有些哑铃式音箱的下面一只单元仅用作重放低频，上面一只单元则重放中、低频，即所谓2.5分频，上述缺点就能克服。
5、 The dumbbell lecture hall sound adopts two identical medium and low frequency speaker units, which are symmetrically arranged on both sides of the high frequency unit, which can achieve good low-frequency and transient response, high sensitivity and power bearing capacity, large dynamic nonlinear distortion and small, but its comprehensive frequency characteristics of the intermediate frequency band often produce low valleys and narrow vertical directivity, Therefore, its mid tone performance should be paid attention to. However, the lower unit of some dumbbell speakers is only used to replay the low frequency, and the upper unit replays the medium and low frequency, that is, the so-called 2.5 frequency division, which can overcome the above shortcomings.
