酒吧音响回收专家认为，首先应从音箱的选择确认入手。最重要的一点必须铭记：包房音箱的灵敏度和功率的配置是系统搭配的关键----因为功放的功率配置要比音箱的额定功率大，因此确定了音箱的功率之后才有了配置功放功率的基础依据。Bar audio recycling experts believe that, first of all, from the speaker's choice to confirm the start. One of the most important points must be borne in mind: room speaker sensitivity and power allocation system is the key, because the power collocation configuration amplifier than the rated power of the speaker, so to determine the speaker's power is the basis for the allocation of power amplifier.
灵敏度高的音箱效率高更容易推响，耗费功放的功率小，失真低。灵敏度低的音箱不容易推响，在发出与高灵敏度音箱同等的声压级的声音时，其耗费功放的功率大、失真也大。灵敏度高功率又相对大的音箱具备了效率高、声压大和稳定耐用的优势基础。The high sensitivity of the speaker is easy to push the high efficiency, power consumption small power amplifier, low distortion. Low sensitivity of the speaker is not easy to push, in the case of the same sound pressure level with the high sensitivity of the sound, the cost of power amplifier power, distortion is also large. The high sensitivity and high power loudspeaker box has the advantages of high efficiency, high sound pressure and stable and durable.
酒吧音响回收专家认为，功放的功率配备应比音箱的额定功率大1.3倍至2.5倍之间，因为功放的功率足够大则音箱的声音会丰满、结实、动态足，功率不够大则音箱的低频表现不佳，声音会感觉很虚。并且功放的功率不足更容易烧坏喇叭。Bar sound recovery experts believe that the power amplifier should be equipped with speakers rated power 1.3 times to 2.5 times, because of the power amplifier is large enough speakers will sound full, strong, dynamic, low power is not big enough is speaker of the poor, the sound will feel very empty. And the power amplifier is not easy to burn the horn.
具有多年的工程设计使用经验的酒吧音响回收专家来总结，专业Hi房每平方米最少应配置25瓦以上的全频专业音箱功率、40瓦以上的超低音箱功率，否则不仅音效达到Hi的需求，稳定性也值得怀疑。Engineering design has many years of experience using bar sound recovery experts to summarize, professional Hi per square metre room should be at least ultra bass frequency power configuration professional speaker power, more than 25 watts 40 watts or more, otherwise not only sound to Hi demand, stability is in doubt.
酒吧音响回收专家总结道，专业音箱(布边低音加号角高音)的声音结实有力、号角的特性使中高音指向性太强，中高音比两分频KTV音箱更明亮清晰、但是声音弹性不及KTV音箱。另外，由于号角提升中高音能量后，如果房内无适当的吸音或扩散设计则容易产生中高音局部过强。
Bar sound recovery experts conclude, professional speakers (bass treble plus selvage angle) characteristics of sound strong, the horn too strong point in the treble, alto frequency than the two KTV speaker more bright and clear, but the sound elasticity is less than KTV. In addition, due to the horn to enhance the treble energy, if the room is not suitable for sound absorption or diffusion design is easy to produce high pitched local too strong.
