THE SPEAKER IS A TRANSDUCER
This means converting an electrical signal into sound waves
Is important to know that
Each home system of HI-FI reproduction, is formed by a chain of electronic equipment quite complex.
Take for example a basic system. It will be formed in this order:
CD PLAYER - AMPLIFIER - SPEAKERS.
Each element of this chain has its own importance. However the last ring, the Speaker System is the most critical. The electronic components of this equipment, must carry from the CD player to the Amplifier a music signal of electrical energy. The Speakers however, will have the onerous task of converting the electrical energy into another equivalent, into mechanical energy, into vibrations. So the loudspeaker is a transducer.
Therefore, the sound waves, emitted from the Speakers, are the electrical signal transformed in a series of compressions and rarefaction of the air caused by the mechanical movement of the membrane of the speaker. Now it should be quite clear why I said that the Speaker System is the most critical point in the Stereo chain.
This introduction is intended to make clear that a Speaker System, born from a complicated design simulated with the computer as a prototype. Following undergoes a serious and complex acoustic analysis that can be performed only by the designer who has created through specific and expensive laboratory equipment. Finally, after long listening sessions and various tweaks to the filters or rather the Crossover, the system can be judged well sounding.
