First look at the unit size and crossover point of the line array speaker. This can already determine a lot of information. For example, if the tweeter is a 44mm diameter tweeter, the safe working frequency cannot be lower than 2K. If the midrange uses four 6-and-a-half inches, you can judge that the design is unreasonable, because Two 6-inch half-horizontal spacing Z should be smaller than 7 inches, and the low point of the interference frequency Z of 7 inches is about 1.34K (242 formula), so for the safety of the unit, if the crossover point is 2K, the midrange is at 1.34K Interference will occur. In order not to interfere, if the crossover point is 1.3K, the diaphragm of the 44 treble will soon be broken. So it is completely unreasonable design.
Look at the impedance curve. Especially for bass, if you design an unreasonable speaker, the impedance curve will quickly be seen. If you design a reasonable speaker based on the unit T/S parameters, the low frequency characteristics will not be bad. If the impedance curve shows that the volume is not enough, or the tuning is low , Or the tuning is too high, or there is resonance, or the volume is too large, the low frequency will not be good. Speakers with poor impedance curves often lack the designer’s theoretical knowledge. In Guangdong speaker factories, copycats are prevailing, and it is difficult for Chinese speakers to enter the European and American markets. One of the reasons is that there is almost no original design, and many people spend a lot of time on it. The original method of trial and error is used to make speakers, and there are few factories that use scientific methods to design professional speakers. This is also the sadness of the industry!
Communicate with developers. Before listening to speakers, if speaker developers can't find a factory for communication, it is often a COPY product. If the R&D personnel themselves are not clear about his design ideas, the speakers are probably not better than that. The structure of the speaker, how to determine the crossover point, the relationship between the size of each unit and the dynamic headroom of the entire speaker.
Whether to consider the mobile system matching. Many line array speakers are used for mobile performances. If the hanging parts, weight, and handle of the line array are not designed for quick installation, the actual use will inevitably not be able to meet the requirements of the performance. Whether the supporting system cabinet is simple to operate, small in size, and light in weight, whether the wiring and power supply in the cabinet are connected properly, is there a dedicated interface on the front of the cabinet for easy connection, and whether the audio system has standard preset programs in it? It’s OK not to send the full frequency to the cabinet. Is there any independent input for the full frequency and ultra-low frequency?
Is there a matching rain cover, is there a matching speaker cable, whether the design of the hanger is reasonable and safe (7:1 safety factor, have you done a tensile test), whether it can be suspended at a single point, and the vertical inclination of the array can be adjusted (There is a porous beam in the middle), whether the transportation package is a flight box or a wheel plate, the lock and wheels of the flight box must be made of reliable and strong materials (Z is easy to break because these two accessories).
