JBL is the largest professional speaker manufacturer in the world, and JBL has accumulated a large number of technical barriers in the production process of one hundred years.
1. In terms of feeling, JBL speakers give people the impression of wide frequency response, great dynamic, and strong high and low frequency sound performance, especially professional speakers, JBL's early 4-series monitoring speakers, with superior plates, neutral timbre, health and rich atmosphere.
2.JBL tone is characterized by high receiving power, between 200-300 W; High flexibility, high sound pressure level above 1 10dB; Good frequency response, flat frequency response and excellent transient characteristics.
3. Flat wire voice coil is an advanced technology invented by JBL company. First used in woofers, then widely used in tweeters, both aluminum and copper. Flexible flat cable has a high duty cycle, and the application of magnetic gap aims at improving flexibility. According to the test, under the same magnetic circuit, the flat wire voice coil can improve the flexibility by about 1dB compared with the round wire voice coil.
4. The spherical top unit of titanium diaphragm is also the first success of JBL Company. The Young's modulus of titanium data is better than that of aluminum data, and the upper limit of high frequency can be greatly widened and the power capacity can be greatly improved by using titanium film high-frequency speakers.
5.SFG symmetrical magnetic field magnetic circuit titanium diaphragm is a patented technology of JBL company. This patented technology ensures that the distribution symmetry of FB value on the magnetic gap is equal to the upper and lower positions of the voice coil, including magnetic flux balance, reducing the inductance of the driving source, heat conduction and other structural settings. Effectively suppress low-frequency distortion and improve power acceptance and damping characteristics.
JBL audio brand is very strong:
1. Throughout the 1970s and 1990s, almost no brand of speakers could really match it. At present, the only speaker that can reach or slightly exceed JBL quality may be GENELEC of Finland.
2.JBL's products are absolutely first-class in the following fields:
The studio manufactures monitoring speakers, numbered 4400 series.
On-site monitoring speakers for recording, numbered 4200 series (small), 4300 series (large) and K2 series (large).
Theater sound reinforcement system, numbered 4700 series and 4800 series; Cinema speaker system, serial number 4500.
Entertainment series, numbered with control at the beginning.
