First of all, the difference between linear array and ordinary loudspeaker lies in the different radiation angles, which can keep a narrow vertical directivity in a wider frequency band. Generally used in large places, the listening effect of the audience in the back row is the same as that in the front row. This can't be compared with ordinary stereo.

If recommended, GAEpro audio series IP2 15 linear array audio is very good, and many five-star banquet hall projects have been done. Of course, JBL is also good. It depends on what model it is, after all, what kind of things are bought at what price.
