This article is a loudspeaker prima which is designed for people who have basic technical knowledge but have not yet before set up loudspeakers or for people who would like to know more about specific types of speakers. To start out, let me explain the basic operating principle of every dynamic loudspeaker. I am not going to talk about static loudspeakers. Those speakers are available but very rare and very expensive. Also, static speakers require a very high voltage and thus pose a danger if somebody was to touch the speaker wire which was not insulated properly.
Dynamic speakers operate by using a magnet which generates a magnetic field. Inside this magnetic field is a voice coil which is attached to a diaphragm. This was coil is electrically connected to a speaker terminal which is usually mounted at the rear of the speaker enclosure. By applying a voltage to this terminal, the quiet will experience a force that is then transferred on to the diaphragm. The final result are soundwaves which are being generated by movement of the diaphragm.
They are some twists in that they are some active speakers out there which don’t have a speaker terminal but instead an integrated amplifier which drives the diaphragm. Some speakers go a step further and integrate a wireless receiver such as Bluetooth speakers and wireless subwoofer models. These types of wireless speakers don’t even have an audio input but instead receive their sound by a radiofrequency signal that is being transmitted by stationary transmitter.
Over 90% of loudspeakers on the market are plain passive dynamic speakers. These types of speakers are rather simple in design and require an external amplifier. Setting up these speakers is rather straightforward. You will need a long enough speaker wire to connect the speaker terminal with the amplifier output. Also, make sure that the power source for the amplifier is fairly stable and that each cable is securely fastened.
You might want to experiment with using multiple loudspeakers if you find the frequency response of the signal speaker is not sufficient for reproducing the full frequency band. They are some subwoofers and tweeters out there which specialize in covering the very low and the very high frequency band respectively. Adding the speakers will enhance the frequency response and give you a better experience. However, you will need to balance the speakers with the remaining speakers.
