then the difference between cheap components and expensive ones aren't that much in sound quality? so if i put components with the same
values but better ones the difference will be very very very small? ... or did i get this wrong??..
Yes, that is correct. If the mid range sound is not good, it is more likely that the mid range driver is not very good. Changing the crossover is not likely to help.
As TLS Guy pointed out, the inductors (large coils of copper wire) in this design are large. Air core inductors of the sizes for L3, L4, or L5 will require a long length of copper wire. That will be expensive. Iron core inductors use much less wire, and will cost less. Iron core inductors introduce a problem because of the higher hysteresis (an electrical property of magnets). However, the use of these iron core inductors
may or
may not create an audible difference when used in speaker crossovers. This is unknown until it is tested in a speaker. Few people have tested this, but many debate it. It is certain that iron core inductors cost less than the equivalent air core inductor, but it is not certain that air core inductors always perform better.
The capacitors in this crossover are also large (C4, C5, C2, and C3). Electrolytic type capacitors of these sizes will be inexpensive. Metalized polypropylene type capacitors of these sizes will be expensive. Some Mundorf capacitors will be even more expensive. Mundorf caps made with silver foil and liquid oil insulators (instead of plastic film) will be extremely expensive. There is also a debate about the effect of different types of capacitors in audio crossovers. But unlike the debate about iron core vs. air core inductors, I am convinced that using different types of capacitors (with the same capacitance values) in audio crossovers will make no audible difference.
thanx for the help.. im quiet the newbie at this
are the values in this pic??
If you are a newbie at this, you will probably have a difficult time building a new crossover with new components. New components will not be the same size as the ones, and they may not fit on the original board in your Infinity speakers.
Here are the values shown in the picture you posted.
