Box and the core inductors are used, then the difference between the two where the children do? In the end what is good? 4 Yongchuan City, Town, Liu Xiaojun zhutuo divider using inductors, inductance is generally a few cents from zero Henry (mH , lmH = I / IOOOH) to more than mh, with air-core inductors and core inductors are available. Air-core inductors of the biggest advantages is linear, that is very stable inductance, frequency, an impedance curve was linear, the Hi -Fi speakers divider choice. Air-core inductors for the divider, the high-frequency channel is very suitable, abercrombie marseille, because the inductance is not able to achieve small size, light weight, but also save wire, low cost; low- frequency channel inductor volume, especially in sub-frequently get lower rates especially if the air-core coils are used, we need more laps around, spending more enamelled copper wire, not only the size, weight increase, cost increase, but mainly to increase The total length of the coil wire, so DC resistance increases. The DC resistance of the speaker in addition to loss of input power, but also reduce the damping factor amplifier a speaker system, have an adverse effect on the low-frequency control. To minimize the inductance of the coil DC resistance is bound to use thick lines around the system, this way, franklin marshall soldes, the inductor size, weight becomes larger, abercrombie france, the cost is also higher. If the iron core inductors using low- frequency channel, can greatly reduce the number of lines circle, volume, weight, cost and other problems solved, but also easy to control the DC resistance of the coil in a reasonably large / J, or less. However, the iron-core inductor has its drawbacks, it is less than the linear air-core inductors, may cause signal distortion. For this reason, some fans of the iron-core inductor dismissive, even if seen with the iron-core inductor, to conclude that the sound will not be good. Obviously, this view is too arbitrary, biased or. Although there are some core nonlinear inductance, but as long as the design is reasonable, the impact of the signal can be negligible, enthusiasts regarded as a classic LS3/5A speaker is one of the most convincing example (LS31L—. .- curse L – I – twelve
