2. INTRODUCTION
Music without sharpness or a voice with no depth is quite boring. No one enjoys listening to a speaker system without a precision clarity in it. Music basically is made up of varying frequencies in the air
A speaker system with perfectly matched crossover networks can be used to produce a hi- fidelity sound output.

4. A three way speaker system is able to produce good hi-fi output
A three way speaker system is able to produce good hi-fi output. It consists of three different types of speakers to handle different frequency contents in a music. The woofer uses the low frequencies, the mid range may handle the speech part and the tweeter is better suited for the highest frequencies in the music.
But these speakers wont work properly until the discrete frequencies are fed to each of them. The result is better achieved using a circuit network of inductors and capacitors also called the crossover network.

5. Types of network Active network & passive network

6. Active crossover
sound system is termed “active” when each driver (tweeter, woofer, sub) has its own channel of amplification.
An active crossover gets wired between the receiver and amplifier and cuts out the unwanted frequencies before the amp wastes energy boosting them, so the amp can focus on only the frequencies you want to hear.
Active crossovers usually have volume controls on every channel or pair of channels so you can keep all the “voices” of the different drivers in balance. Some active crossovers include other sound-processing features like equalization for further tweaking of the sound to your personal satisfaction.

8. Passive crossover
A passive crossover doesn’t need to get hooked up to a power source to work.
There are two kinds of passive crossovers:
component crossover
In-line crossover

10. Component crossover
Passive component crossovers step into the signal path after the amplifier. They’re small networks of capacitors and coils usually installed near the speakers.
Component speaker systems come with their crossovers set for optimum performance, and they are simple to install and set up.

11. In-line crossover
Besides passive crossovers that operate on speaker-level signals and connect between your amp and your speaker components, there are also in-line crossovers that connect before the amplifier.
They look like little cylinders with RCA connectors on each end and simply plug into your amplifier’s inputs.
