is the best speaker belong to concert speaker category?

There is no specific brand as the large concert speaker systems are custom built and may have different types of speakers in them from several makers.

Some brands used for big concert systems are JBL, Electrovoice, Meyer, QSC, Renkus-Heinz and the like. A system may use Electrovoice for front of house, Renkus-Heinz monitors and JBL side fills. Or sort of combination.

Also note that concert systems only work in very, large rooms. The sound does not come together for 25 to 50 feet from the speakers. Closer than that, they sound like crap. All you get near the stage is hearing damage.
