The sound quality of Best Powered Speakers is much higher than the previous ones, but also its price is higher due to, among other factors, that there must be at least one set consisting of 3 different types of speakers ( woofer, medium and tweeters ; One for each channel or basic sound frequency) to enjoy acceptable acoustic quality.
Woofers: emit low (bass) frequencies.
Subwoofers: they support higher powers than the rest of the types of loudspeakers listed here, and they are in charge to emit sounds with frequencies inferiors to the serious ones.
Means: As its name suggests, they emit mid-range sound frequencies.
Tweeters: Also called piadores since, like most songbirds, they emit the highest (high) sound frequencies. This is the type of Best Powered Speakers that are more sensitive and delicate, so they should be treated with great care and should not be approached under any conditions to the maximum of their power, as recorded by the manufacturer.
Cables and connectors
There are basically 3 types of cables that can be found in any sound system: power, speakers and various connectors.
They are the ones that present a greater danger to the people when they are manipulated. Through them they feed, with electric current, the devices that need it (sources, amplifiers and some types of loudspeakers).
To correctly handle this type of cables, we recommend reading the free guide How to plan the electrical installation of your home , with keys to protect electrical elements such as cables and outlets, ensuring the highest possible level of security for system integrity and Of the people who make use of it.
Like electrical wires, copper wires are covered (usually and in the simplest cases) with plastic protection, but in this case only two phases (the ground wire is not necessary) and a diameter reduced. Those that are specially marketed for this purpose are usually distinguished by two colors, usually red and black (positive and negative), so that it is easier to respect the respective polarities (+ -), a particularly relevant issue that can not be omitted in any way.
There are basically two types of connectors depending on their shape: males (or aerial) and females (attached or chassis). The former have a cable that ends in a connector that must be inserted into a chassis, which in turn is normally designed to be integrated into a device to which the overhead connector must be connected.
Connectors on sound systems
Apart from the form, logically the function of each connector will determine its membership in a group or another defined by these functional characteristics. We basically find the following types of connectors depending on their functionality:
XLR connectors : are connectors with legs or “pins” (usually 3) males, and females with respective slots, especially used for connecting microphones and audio input devices in professional or semi-professional sound systems.
Euroconnectors: less and less used, have been overtaken by HDMI and USB connectors. They were used to connect video and audio sources to other playback devices.
RCA: despite increasing competition (especially with the USB and HDMI connectors), still resist pressure. They have 3 jack type terminations, usually different in color (yellow for the picture, and white and red for stereo sound channels). They are used to connect video and audio sources to other playback devices).
Jacks: These are typical wires often with ring-ended terminations, used for connecting headphones and / or some sound / video sources. They can come in different shapes and sizes sizes (a quarter inch, maxi-jacks , or an eighth of an inch, mini-jacks ).
HDMI: are the video and digital audio connectors. They offer better quality and optimum definition of the sound and video transmitted through them.
Cables in sound systems
USB: widely known by the majority of the public, are used to connect digital storage devices (mainly) with computers and video and / or sound players, among others.
