I once worked in the professional audio industry, and I would like to give you a suggestion. If the area is not too large, just use a set of home audio worth more than 3,000 yuan and add a reverberator (I guess you won’t have many channels. Input), low-priced professional speakers are shoddily manufactured and very profitable (some as high as 500%). For speaker amplifiers and reverberations, you can choose Tianyi, which is a well-known brand in the domestic HIFI industry and has a very high cost performance
