How many rated ceiling speakers do you usually use to play hotel background sound? It covers an area of 400 square meters and has 8 points.

If there are only 8 points in 400 square meters, I think there will be a problem that sound can't be heard in some positions. The background music mainly plays intermediate frequency and a small amount of high frequency, so the caliber of the ceiling speaker is 6 inches. In addition, since the ceiling is within 2.5-4m from the ground for playing intermediate frequency and high frequency, the average power of each speaker is below 10W, which is enough, but there are many points, about10m. If there are few dots and the power of a single dot is high, some areas will be very noisy, which will affect the conversation of guests, and some areas will be very quiet, and the effect of background music will not be achieved.
