1, NS series of speakers using computer-aided design: the use of advanced equipment with engineering application features integrated tank calibration, with OTO sales advanced manufacturing technology professional speaker, and ensure the high quality of the product. Selection of imported paper tray unit, with high-precision oxygen-free copper inductors, polypropylene capacitors United States BOSE professional speaker, sound more pure. 2: NS Series speakers as an independent full-range speakers, eliminating the need for an external crossover drive trouble, a strong low-frequency driver and a 1.75 inches (44.4mm) high frequency compression driver mounted on a constant directivity of 100 degrees x50 Elliptic fiberglass horn on. HF horn can be rotated so that the multi-angle enclosure both horizontally and vertically positioned, make the system more compact. Suitable for outdoor mobile sound reinforcement systems, indoor SHOW it, shake it slow and fixed installation systems and other places. 3: small box, big power, high sensitivity. 4: multilateral type box, suitable for more applications. Problems coverage angle 90 degree rotation horn, solve different applications: 5. 6:12 grain M8 nuts hang out holes plus standard of stent struts, durable and easy to install. 7: sound soft but just professional speaker, treble delicate and beautiful, clear and transparent. IF round and plump and flexible professional speaker leading brands, real and natural. Reducing the human voice and musical instruments give you an impact. And WS-15, WS-18 or WS-218 subwoofer, etc. supporting the use of the composition of full-range system to expand or enhance the low frequency output, but will produce unexpected results. What are the characteristics and different lines Chen point source and point source common is it? Principle linear array is mainly through close interference with the horn tweeter and woofer so that the sound is formed between a cylindrical wave, the general points out sound source is a spherical wave, spherical wave from the doubling of energy consumption per 6dB, The cylindrical wave only 3dB, and therefore spread quite far from the line array is generally used for large-scale performances. Also interference between line array speaker cabinet design is reasonable, the same number of ordinary speakers much sound coming out of a heap is certainly muddy sound than linear array of outstanding quality professional speaker | Wuhan Jiuhua video (Certified ) | Professional Speaker by Wuhan Engineering Co., Ltd.
