酒吧音響回收專家認為，首先應(yīng)從音箱的選擇確認入手。最重要的一點必須銘記：包房音箱的靈敏度和功率的配置是系統(tǒng)搭配的關(guān)鍵----因為功放的功率配置要比音箱的額定功率大，因此確定了音箱的功率之后才有了配置功放功率的基礎(chǔ)依據(jù)。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.
靈敏度高的音箱效率高更容易推響，耗費功放的功率小，失真低。靈敏度低的音箱不容易推響，在發(fā)出與高靈敏度音箱同等的聲壓級的聲音時，其耗費功放的功率大、失真也大。靈敏度高功率又相對大的音箱具備了效率高、聲壓大和穩(wěn)定耐用的優(yōu)勢基礎(chǔ)。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.
酒吧音響回收專家認為，功放的功率配備應(yīng)比音箱的額定功率大1.3倍至2.5倍之間，因為功放的功率足夠大則音箱的聲音會豐滿、結(jié)實、動態(tài)足，功率不夠大則音箱的低頻表現(xiàn)不佳，聲音會感覺很虛。并且功放的功率不足更容易燒壞喇叭。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.
具有多年的工程設(shè)計使用經(jīng)驗的酒吧音響回收專家來總結(jié)，專業(yè)Hi房每平方米最少應(yīng)配置25瓦以上的全頻專業(yè)音箱功率、40瓦以上的超低音箱功率，否則不僅音效達到Hi的需求，穩(wěn)定性也值得懷疑。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.
酒吧音響回收專家總結(jié)道，專業(yè)音箱(布邊低音加號角高音)的聲音結(jié)實有力、號角的特性使中高音指向性太強，中高音比兩分頻KTV音箱更明亮清晰、但是聲音彈性不及KTV音箱。另外，由于號角提升中高音能量后，如果房內(nèi)無適當?shù)奈艋驍U散設(shè)計則容易產(chǎn)生中高音局部過強。
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.
