These days it’s difficult to find computer systems, monitors or cases without some form of default/built-in speakers. But these PC Speakers are commonly basic or cheap in nature. These conventional speakers used to give output at 5.1, 6.1, and 7.1 surround setups but with the advancement in technology more innovative PC Speakers with a range of 2.0 (stereo) or 2.1 (stereo with subwoofer) models are flooding the market. A computer speaker initiates waveforms with the aid of Programmable Interval Timer. The aim of PC/computer speakers is to give uniqueness and create impressions of polyphonic music or sound effects into computer games or to any multimedia output.

It is not out of place to mention here that the first IBM PC model 5150 employed a standard 2.25 inch magnetic driven speaker which worked as just a tone generator The main purpose of generating or creating this sound was to serve as a feedback in case of hardware failure. There are many embellishments of computers available which let you enjoy and enhance the multimedia content of your PC speakers. They came in a wide range of designs and quality. Some more advanced (modern) PC Speakers provide state of the art features like bass and treble control and subwoofers which somewhat enhance the output, if you have a big budget you can even get speaker with built in control systems. Imagine that a computer speaker for computers with its own built-in computer? In laptops the default speakers come bundled with a basic integrated speaker, which unfortunately produce substandard sound. In this situation some audio software can augment the output of these speakers. Currently PC speakers are also powered by USB ports.

Many programs in a PC like ScreamTracker, Impulse Tracker, Module Player 1989 including device drivers for Linux and Microsoft Windows, have the capability to play pulse-code modulation (PCM) sound with the help of speakers. Several PC games like Pinball, Space Hulk etc., are the proof with the help of computer speakers they were able to produced superb music from computer speakers.

In some computers, Computer Speakers [] are affixed directly to the computer’s motherboard, in others the speakers are attached to a lead. Some of the common features of PC/computer speakers are: Volume control along with bass and treble control, a remote volume control, a led power indicator, A 3.5-mm or 1/8 inch headphone jack.

The most common type of car speakers are called coaxial speakers. Usually most car manufacturers will include at least a pair of coaxial car speakers in their models. Coaxial speakers are available as 2-way-, 3 way and 4-way speakers depending on their configuration or to be more specific the number of tweeters in the system. The most basic version of coaxial speakers, the kind that you would generally find in older cars has mid range cone woofers capable of producing mid range sounds. But the latest versions will also include at least one tweeter for high frequency reproduction. A tweeter is a device that helps your system to reproduce high frequency sounds, minimize sound distortion and gives clearer and more defined sounds. An increase in the number of tweeters will add more details to the sound. So while two way coaxial car speakers have one tweeter, three way speakers would include two tweeters and so on.

Many car manufacturers talk about the amazing effects of the 6 piece car speaker system in their models. But essentially this system just includes 4 mid range woofers with 2 detached tweeters and this is what you would get normally as well when you buy a car. So, if you are being charged extra for this you know you are being cheated.

A component car speaker system comprises of mid-range woofers, tweeters and cross over filter networks. However, the tweeter in the component car speaker system is separate with the cross over filters added for increased sound clarity. The filters channel sounds that are component specific that is only a sound range that can be handled by a specific component is channeled to it. For example, only high frequency sounds will be channeled to the tweeters that are capable of handling them while the low frequency sounds are channeled to the mid-range woofers. This significantly improves the sound quality by minimizing disruptions and distortions.

If you were to compare the two car speaker systems, namely coaxial and component, in terms of their price, the component car speaker systems are considerably more expensive. But the better sound quality makes up for the increased cost. Generally a three way component car speaker system is more than adequate to produce impressive sound quality. Since most new cars come with pre-installed or factory installed car speakers you may want to check if they have the cross over filters.
