Active with volume control LED display for active fret fret Chi Hui Pu Technology

Roughly speaking, if you like the frets with a modern look, as long as with subwoofers, do not have to worry about its quality performance due to design reasons, not as good as the traditional style of the speaker (only on the principle of analysis, without regard to subjective feelings of judgment the sound quality is good or bad). It frets that 360 sound field system, the sound field generated from the theoretical analysis must be better than conventional speakers, which sound more suitable for watching movies and music. Waterproof frets power 50w 60w 70w 80w 120w frets install more than just a speaker cone angle in the housing, the sound column is more than just a speaker through permutations and the same phase connected together. Sound column directional characteristics in the horizontal direction and almost single speaker, but in the vertical direction is greatly improved. As it spread like a fan in a horizontal direction, but appear strong directional characteristics in the vertical direction, forming a thin much thicker near the "plate" like three-dimensional radiation effect. Phase column installed near the sound stage proscenium, this "sound plate" points the audience, with a strong beam of sound energy radiated to the back of the auditorium, the vertical distance between the front speakers due to different causes of each other weakened, in order to reduce the impact of high frequency comb effect sound effects, on the use of a plurality of closely spaced tweeter, with a minimum interval arranged in a line (20KHz ideal wavelength of 1.7cm, requires high-frequency or full-range speakers Center separated by less than 1.7cm, but the hearing range of the human ear can not easily achieve the desired 20-20000Hz, and the ear of the high frequency of the corresponding age became weaker, so it does not have to be so close, it should be based on the actual circumstances, of course arrangement as closely as possible); while the woofer bass Since longer wavelengths, you can use a little less of the speaker unit and the front panel evenly to fret, not too tightly packed to link wavelength.
