Such speakers are very much favorable if one desires an improvement in the car audio system.  These are as follows:

Coaxial Speakers

These are the most common type of car speakers, installed by manufacturer. Such type consists of two pairs out of which one pair is in the front and other one is in the back. Though some manufacturers can offers up to 8 speakers. It consists of a cone woofer also with one tweeter mounted on top. The woofer can take care of mid-range frequencies whereas the tweeter can take care of higher range frequencies.

Component Car Speaker System

In this system, the tweeters and woofers are separate. It can include set of crossover filter network which essentially can improve sound quality by the distribution of audio signal to the relevant components. The high frequency signal is diverted towards the tweeter. Also the lower frequencies are directed to the woofer.
Let us now discuss the other important component of car audio system which is car amplifiers.
Car amplifiers generally offer better sound quality by driving the speakers. It obviously improves the quality of music and makes sound cleaner at all volume levels. Car amplifiers help to enhance signal from stereos to car speakers, and also acts as a self-sufficient power source.

The various types of car amplifiers are: four channel, two channel and mono. Mono car amplifiers are the single channel amps, and are matched to work for low frequency. The four-channel car amplifier helps to enhance signal to two speakers.

How Power Amplifiers Create Magnificent Sound Effects?

An amplifier is used in devices wherever sound is produced such as radio, TV and music systems. The significance of an amplifier is that it helps in the proper functioning of all audio devices. A power amplifier is a device that enhances the sound quality and provides better music experience.
Power amplifiers are the one which can convert low power frequency signal to higher frequency signals. Their categorization is based upon the amount of power delivered to the load. Classification of an amplifier is done based on linearity, signal gain, efficiency and output power.
Power amplifiers find their use mostly in transmission chains and, hence require attention for power efficiency. According to latest survey, power
amplifiers is often used in audio and radio frequency applications in various industries which include medical and military industry. There are ranges or classes of power amplifiers.
There are many different types of power amplifiers which can be purchased in the market -

• Tube amplifiers –
Also called as vacuum tube amplifiers as they make use of the vacuum tubes to increase the signal amplitude and power.

• Solid state –
These are the ones used mostly in transistors. These came into existence in the late 60s and early 70s. These can easily control all the bass frequencies than tube amplifiers.

• Circuit types –
It depends on the circuit types; they are classified into Class A, Class B, Class AB, and Class D.

• Audio-power amplifiers –
These are also known as the small signal power amplifiers as they raise power level of signals with audio-frequency range up to 20 Hz- 20 kHz.

• Radio-power amplifiers –
These are also called large signal power amplifiers which also raise the power level of signals. It easily amplifies specific frequency or narrow band of frequencies.
The power amplifier is often used to produce loud sound and also make it very clear to show the difference in acoustics between a noise signal and soothing sound.
As power is an important factor in such amplifiers the amount of power needed can be categorized based on the rule of thumb
• Medium Bands– 3 to 4W per audience member.
• Large bands– 5 to 6W per audience member.
While stepping up into the market the main thing that comes to our mind is the budget as more the power, the greater the cost of it. If budget is a constraint and if less powered amplifier is purchased it must be kept in mind that there is not any clipping. The other factor is the product specifications i.e. power that flows into the loudspeakers is less than the required it should be make sure that it should not damage the loudspeaker or the system, and create an unpleasant hearing due to the distortion. These also find use in home theater systems .
Power amplifiers find a major role in bringing in the best possible sound effects and hence are in demand.

Brief Introduction of Hi Fi System Types and Working

The word Hi-Fi system simply means where there is precise reproduction of wonderful sound and that too without any distortion or noise. Hi-Fi or high fidelity is the word used by home stereo and audio listeners and enthusiasts also called as audiophiles.
To know what exactly (Hi-Fi) high fidelity is we have go back to the history. It was later in sixties that the High Fidelity industry had grown to its fullest, but its demand started to dim after its conversion to stereo sound system. Also after that the transistor revolution came into existence. Ideally, such systems can eliminate noise and distortion, and give an accurate frequency response. Music enthusiasts or audiophiles can collect the home systems components with hifi stamp. These systems are incorporated by creating new ideas and devices. Hi-Fi speakers play a very important role in enhancing the quality of music. Also consumers have to choose the right speaker type to suit their specific HiFi music needs.
An ideal hifi setup includes CD players, digital audio tapes, digital audio broadcasting, an amp, pre amp, and home theater speakers. Many people try to connect to music servers, Wi-Fi equipment, TV set up, and DVD player. As compared to the cost of home theater systems the high fidelity system can be purchased at a reasonable price. It is not compulsory to purchase all the components of the high fidelity system at a time. This option in turn improves your hi-fi system and makes it easier and simpler. There was another major breakthrough in the audio industry with the production of innovative vacuum tube amplifiers which solved many problems.
In short there are three step work process in high fidelity systems which is the music source, the amplification of sound signals done by amplifiers and last but not the least the loud speakers which renew the amplified signals into sound. The playback tools included are DVD player, a CD player or TV.

The type of Hi Fi system is based on three kinds depending on their output power, design and functions. These are as follows :
• Midi Hi-Fi is made by accumulation of different elements like CD player and twin cassette player. These are very much flexible and easy to be utilized for.
• Mini Hi-Fi System, their elements are not as big as midi hi-fi systems and do require lesser place than Midi systems.
• Micro Hi-Fi systems are denser and its elements are built into a single component. Their output is minor and is mostly used at home. Its biggest advantage being precision quality and clarity.

Significance of Guitar Amplifiers in Rock Music

Guitar amplifiers simply amplify the sound signal fed to it from the guitar and it in turn drives the guitar loudspeaker. Electric guitars are considered a very passive instrument. Main reason behind it is that they do not need any direct power supply. Very few of them are powered by an onboard battery. Actually it’s the vibration of strings which produces signal in coil. A guitar amplifier is basically called a combination amplifier, which consists of a speakers and amplifiers. Its cabinet consists of processors, knobs, dial, buttons, which control the volume set.
In case of the guitar player, an amplifier helps to play one role it only makes the guitar louder. It equalizes the signal and removes distortion or any other effects. The essential task of the guitar amplifier is to produce boosted sound volume with clarity. The increased amplitude of output wave leads to the proper functioning of guitar.
Everyone is fully aware of what the amplifiers do; it takes the guitar's signal and makes it audible by boosting it to such amplitude which is enough to drive home theater speakers .It is always there with the sound signal and electric guitars have the option to control this distortion. There is some difference between amplifiers of electric guitar and that of tube amplifiers. The amplifier used in stereos, reproduce and amplify sound with minor distortion. Whereas with electric guitar amp, musicians need both distortion and also clean sound. What distortion means, it is produced whenever the signal is too powerful for that circuitry of amplifier. The various types of guitar amplifiers available in the market are electric guitars, acoustic guitars bass guitars and many others.
If the sound that comes out of the amp and speaker is loud enough, it will automatically cause guitar's strings to vibrate. It depends on whether the signal fed to the input of the guitar amp works or not otherwise the signal might be fed to the preamplifiers whose output is fed to the guitar amp. With the recent advancements in the technology adopted by musicians, the electric guitar still has a prominent place. It helps to inspire entirely new type of music. Since its invention in 20th century, electric guitar is considered the most prominent instrument in rock music. Rock band is really incomplete without it.
All the above information is just a brief introduction about guitar amplifiers, there is lot much to know about it in-depth.

Brief into Amplifiers and its Various Types

 An amplifier is a device that is meant to make the signal stronger as it passes through it. Many different types of amplifiers have been launched in the market. There are some of the amplifiers which use electricity such as electric guitars and other PA systems and are called the artificial amplifiers. Artificial Amplifiers allow you to fully control the tone and volume and are most preferred by music players.

Tube amplifiers require the occasional maintenance it hardly depends how one handles them.
Tube amplifiers are always the first choice of the buyers all because of its benefits. If by chance the regular maintenance is missed then it creates malfunction and also leads to the poor performance. Tube amps are the favorite among music lovers as they are distortion less. The purpose of a power amplifier is to take a signal from a source device and deliver it to the loudspeaker. They do have a power rating and its units are called watts.
The power rating of an amplifier is measured in terms of load impedance whose units is ohms. Its most common load impedance are 2 ohms, 4 ohms, and 8 ohms. They usually sound louder than the solid-state amplifiers which are of same wattage. The tubes need to be changed occasionally as otherwise its performance can deteriorate with time. These are considered one of the important component of the home theater systems.

Vacuum Tube Amplifiers Costly But True Value for Your Money

Vacuum Tube Stereo Amplifier consists of vacuum tubes which are used to amplify audio, power and other alternating current signals before transistors were invented. This vacuum technology is still used by guitars. This tube amp basically operates on vacuum tube or valves. Audiophiles usually desire these tubes as tube amplifier is considered ideal for home listening as it produces natural and smooth sound.
The Valve tubes in the vacuum amplifier produce even harmonic distortion and the sound produced is very pleasant to the ears as compared to that of transistors. Most musicians around the globe prefer to use such amplifiers
because of their high reliability. Also known as Valve amplifiers, they use electronic components called Vacuum Tubes" or "Electronic Valves" for amplification purpose in the circuit and do not use solid state transistors.
A tube amplifier response is different as compared to a transistor amplifier towards the signal level clipping. In case of tube amplifiers, the transition is less abrupt compared to transition amplifier.

It is based on the technology which was invented around early 20th century: the triode. Its major component being a triode provides high-power i.e. distortion less audio amplification. Commonly used vacuum tube amplifiers are the Class-A amplifier circuit and are commonly found in guitar amplifiers. This type of amplifier circuit issued where a high fidelity output signal is required.
These tube amplifiers are used by musicians who always want to produce warm sound from guitars or other musical instruments. These are a bit expensive in comparison to other amplifiers reason being quality doesn't come cheap. It is the cost of raw materials in it that is more in number as compared to solid state amp and also the labor required is more. With the result the end product gives sound which is totally the true value to the money spent.
Choosing the right amplifier out of many totally depends on the style of music you want to play. A 15 watt will be enough for use at home. For those who can really spend more can opt for 30, 50 or 100 watt amps in combo or single cabinet configuration. It all depends on the user’s choice and requirement.
Their classification depends on the tubes which are used.
• Preamplifiers tubes used mostly in guitar amplifiers
• Power amplifiers tubes have sound and output power limit.
The above information describes the vacuum tube amplifiers in brief, for music lovers there is lot more interesting to know about the same.

Amplifiers With Desired Specifications

The amplifier can take up the signal from head unit and increases its amplitude to drive the speakers. It is always preferred to use separate amps for high and low frequency but its is not always important. There is one biggest problem if only amplifier is used for all frequencies and it is that the different frequency levels cannot be adjusted. Sometimes amplifiers are used for the low frequencies (bass) and then their head units which have built-in power drive the higher frequency speakers. These are very much in use for the car audio system to give maximum boost to the car speakers.  

There are many basic parameters which are to be looked upon while selecting the power amplifiers:
RMS Power: The output power from amplifier should always be matched to what the amplifier needs to drive the speaker.
Power Supply: The amps which have regulated power supply will surely supply constant power regardless of input voltage.

Room Correction Systems a Breakthrough in Audio Industry

It is a well-known fact that every room suffers from high or low frequency modes and dips and also the sound waves which bounce inside the room and produce interference pattern. The room correction system can soak up the sound waves energy as it approaches the walls, as there is nothing to reflect, to cause interference peak in the room. It is an extremely effective and affordable solution, but it takes up a lot of space.

Digital room correction is a process where in the digital filters are designed to amend or change any of the unfavorable room acoustics effects and are applied to the input of a sound reproduction system.  These modern room correction systems can help to produce substantial improvement in time and frequency domain response of the sound reproduction system.

The digital room correction system configuration can be done merely by measuring the response of room at the listening location of the loudspeakers. The computer software reverses the effect of the room and also the linear distortion in the loudspeakers and amplifiers. The room correction filters are causal, there is always some delay. For audiophile the room correction system can feature the sound of bells and whistles which make the ears to tingle.
Like any traditional component, the room correction system was constructed to help installers correct the acoustic problems due to various room dimensions. Through link up of the PC which runs the room correction software people can measure their home entertainment response to sound and later system can create a model called Room Knowledge. The correction system puts all the heavy audio data into use by the correction of frequency irregularities and unleashes full capabilities of the audio system. This digital room correction is used to help home theater systems to gain significance as it can produce better sound.

The Digital room correction is the new advanced form of digital technologies that allows user to fine-tune their system to eliminate any of the room interaction. These systems should be expertly crafted as they are not cheap enough.The Digital equalization technique provides very narrow response peak and notches, also with precise phase correction so the idea of electronic room-correction has become very popular again.

The room’s response always varies throughout the area, as different reflected frequencies interact with each other at different places. To conclude it is for sure that these systems have become the need of the hour.
