所有的扬声器都有其强项和弱项，在有限的预算下，低价扬声器容易吸引人，但却往往得不到优质的效果，而对于任何价位和档次的济南音响而言，都需要有相应的参考规范或指南，简单来说我们可以从以下四个方面测试济南音响扬声器的品质：
All speakers have their strengths and weaknesses, with a limited budget, low speaker easily attract people, but can not get good effect, and for any price and grade of the Ji'nan sound, all needs to have the corresponding reference standards or guidelines, in simple terms we can from the following four aspects test Ji'nan audio speaker quality:
1.低频的质量 劣质扬声器所产生轰耳若聋的低频是那种臃肿松厚、短缺档次感和硬朗感的声音，好的低频应是干净明快，档次清楚，不会快人快语，即便各种低频乐器如大小鼓声、低音吉它和钢琴的低音，都能容易地分辩出来。所以不要容易低频的量感所蒙骗，劣质低频不如干净的声音来的自然舒适。
1 low quality inferior the speaker produces detonation ear if deaf low frequency is the kind of fat, short thick loose sense of quality and strong sense of sound, good low frequency should be clean and crisp, clear grade, not straight talk from an honest man, even if low frequency instruments such as drums, bass guitar, and the size of piano, bass, can easily distinguish out. So don't easily low frequency quantity feeling deceived, inferior low frequency as clean sound natural and comfortable.
2.中频的人声 人声是最常听到的声音，优劣其实并不难觉察，注意人声能否有不平常的鼻音或被抿着嘴发声的感觉。一些扬声器的“箱声”同样会干扰中频，令此频段的声音隐约不清。中频音染相对于其余频率音染而言更为严重，多数可听到的声音频率，或是音乐的频率都集中在中频范畴，这点对乐曲而言都会成为重播的阻碍。
2 if the vocal sound is most often heard the sound of the merits, is not difficult to perceive, pay attention to voice can have unusual nasal or be pursed her lips sound feeling. Some speakers "box" will also interfere with intermediate frequency, make the band sounds vaguely not clear. If the sound to dye relative to the remaining frequency noise pollution is more serious, most can hear sound frequencies, or the frequency of music are concentrated in the intermediate category, it will become a replay of the impediment to the music.
3.高频的柔韧感 劣质济南音响  http://www.jnzqyx.com/ 扬声器的高频尖声插耳，听得人头痛欲裂的，极端状态下把优雅的小提琴或女低音的美声变为尖利的噪音。同样，低音中不同乐器会产生不同质感，好的低音是能分辩出来的。再优劣一级的高频甚至能分辩出两把不同年份不同木质所奏出的不同音韵。最易控制的要决是，好的低音是不会令人越听越累的，幼滑而具档次，高至最高处仍可容易闻声。 4.低音量及音场结像 一些扬声器在低音量时较稳定，但当音量提升到某个指数便会失真，或“拍边”，出现各种非录音中的音乐信号。详细而言，若管弦乐是喜爱乐种之一，则必需通过此关。符合规范的扬声器在肯定水平上做到声音离箱，营造出清楚的音场和结像，显示出不同乐器的分点位置和质感。
High-frequency shriek flexible 3 high-frequency feeling inferior Ji'nan audio loudspeaker plug ears, hear the head splitting headache, extreme state of the bel canto elegant violin or contralto into sharp noise. Similarly, the bass in different instruments have different texture, good bass is able to differentiate. Then the merits of high level can even distinguish different phonological two different wood to play the. The most easily controlled condition is good, the bass is not a more listen to more tired, smooth and with high grade, can be easily heard to the highest point. 4 low volume and the sound field node like some speaker is stable at low volume, but when the volume up to an index will be distorted, or "time", the emergence of various non music signal recording. Specifically, if the string is one of the favorite music, you must pass this pass. In accordance with the norms of the loudspeaker on certain level do sound from the box, to create a sound field and clear like, showing different instrument point position and texture.
优质的济南音响扬声器播放出来的声音能浮现丰润的音乐感和空气感，和音符的弹跳力，人声和乐器声不会纠缠不分，展示出整幅过细有序的音像。久听之下也不会令人耳朵疲累。
The quality of Ji'nan audio speakers broadcast voice can emerge and music sense and sense of air, and note the bounce force, vocals and instruments sound not entanglement is not divided, showing the meticulous orderly video. It will not be long ears tired.
