When B91 singing
Let's start with Queen Band through the song “A Night As The Opera”. The narrow baritone range of sound can not run down causes the feeling of hard bass sound and the baritone male voice does not show the right sweet voice. High-frequency range also shows more highlights but still a lack of details. Through the song of Hotel California, the bongo drumbeat is heard well but is still not emotional due to lack of the long drone out, gradual turn off the drumbeat, and the voice is entirety impressive thanks to a clear separation of background music. A general feel of B91 is a set of speaker with a voice quality on high-frequency range, harmony, and suitable for classical music. With music and sound in the movie, B91 has shown all of its advantages thanking to a good ability to show on the middle and high frequency range. The sound on the middle and high frequency range in the movie is very impressive. With Hero film, the variation sound of an arrow in the wind gravitates from this ear to another makes viewers feel like you are flying with the wind. The sensitivity of the low and baritone sound at low frequency of around 500Hz limits feeling when watching movie. The footstep of army with 2 trillion people but like as "any person is going on the floor". However, this frequency range has a little in the movie in general, so the advantage in the middle and high frequency range still make viewers have high emotional changes according to the order performance of the movie. It is a sweet choice.
