Audio Tips: Select Fullrange Ideal Speaker
Car Audio December 18th, 2009
Full-range Speaker fullrange (wide band driver) is not only suitable for the contest, but also suitable for the free daily tuning pillar A from the large box speaker system stacked, so it will not interfere with the view when in use.
Create SO’mers are interested in the model fullrange speakers can understand this one article. According to Ricky from home audio Revealing Sound, in the Tangerang area, select the fullrange be based on dimensions, materials, size of box.
Problem dimensions, Ricky continued, due to limited space in the car, then usually a commonly used measure between 2 “-4″. “The measure was virtually menghalangin safe and no driver’s view, the article this is very important for driving safety,” said Ricky.
As for the volume required, said he was ready smile, it is important, because the average driver to take fullrange box above volume 1 liter. So its placement in most cars become impossible alias unsafe.
“It would be better if the drivers will be able to work to maximum volume size under 1liter, ideally /-250ml-500ml,” said Ricky.
Quality Materials
Consider materials, to participate the election material effect on endurance driver in the car. Because the temperature changes in the car can be fairly extreme, from the high heat when sunburned, humid rainy season and at night. Plus the use of air conditioning, so the resistance becomes konus important materials.
Material from the paper that is not special treatment is usually most decrease resistance, so that becomes easily torn and not rigid.
While treated paper is usually quite resistant to temperature changes. “Material metal such as aluminum, titanium, plastic materials such as polypropylene, Kevlar material, carbon fiber materials are good materials for usage in cars because of resistance to these extreme weather changes,” Katya man who had lived in the land of the Kangaroo.
Frequency Range
Fullrange frequency range is ideally 20Hz – 20kHz. “Due to the limited size is usually in the frequency range of cars that can be achieved average / – 200hz to 20kHz. Where these drivers dikisaran play 200hz-8khz,” said Ricky.
In Indonesia, the use of the vehicle fullrange commonly used originally started I think it was in 2005 with the entry of fullrange drivers. At that time, maybe the price factor and the reliability of the drivers berkendala of the cooling system with liquid voicecoil who like to leak ferrofluid. What makes it less so boom.
We have many options with good fullrange driver and a lower price, you could say fullrange already widely used because of its superiority can bring the full frequency tone and sound effects are also more coherent, because the use of a driver who can bring almost all the frequency spectrum. Use of midbass used to assist low tone.
Sound Silencer Cabin Able to Reduce Car Noise
Car Audio October 16th, 2009
Many factors make sense of comfort while they are inside the car cabin, one of which is the level of silences.
Each car has a damping system with a level of silence different, especially among premium car class with the entry-level class. The higher the level of cabin space of silence means that the minimum noise that enters the car.
Almost all cars have a damping system is lacking, especially for entry-level class. Most of the noise from outside, such as another vehicle engine sounds, the roar of the tires spin, the rush of rain water diatap (roof) even up to the sound engine itself is still heard from inside the cabin.
Of course, all the noise they can reduce the sense of comfort and distraction when we’re inside the car cabin, but all that noise can be overcome by add-dampening sheets tailored to maximize damping for the car cabin noise level decreases.
According to Andrie, fitter from Bassindo, in order to function well reducer, fitting reducer should be at the required point on the body of the car, as in:
1. Doors / Doortrim: To reduce resonance in the plate body, usually the installation silencer is more directed dititik for audio, so voices can be heard more midbass deep (clear and round).
2. Machinery and barrier wall Cabin (Firewall): To reduce the entry of the engine into the cabin.
3. In this section spakbor (Space Wheel): To reduce noise tire rotation (Road Noise) as the car drove.
4. Kap Machine (Engine Hood): It can reduce noise from the engine and keep heat in order to paint the hood does not quickly fade.
5. Cabin Floor (Floor): Can maximize damping for noise, like the tires and axle and the heat coming from under the car.
6. The roof (ceiling): Can make more reducing cabin heat and minimize the sound of rain hit the roof.
Material Type and Silencer
Many brands and types of absorbers that can be found in the market, each with quality materials and capabilities to different thicknesses. Silencer itself there is a thickness of 2 mm and 3 mm. Problem type and material, almost every manufacturer makes a variety of damping silencer made in the function to be installed on a particular section, each assembly point has a type and a different damping materials, especially between the hood and doortrim.
Generally, the sheet-shaped silencer, but this time there is also the producer who makes a silencer with other forms, especially those devoted to the door. For this type of material, damper manufacturers who call their product is made of rubber mixed with Visco elastic materials, semi-synthetic elastomer blends elastoplastomeric materials and so on. Market is very much a silencer brands, among others are like: Automat, Vibra System, Checkmat, Dynamat and much more.
“There are things to remember, too, fitting a silencer to be adapted to the needs, the installation should not be too long .., Why? .. Because if the silencer attached too much and thick heavy weight can make the car increases, the effect could be the car feels a little more extravagant fuel, the installation technique was not to damage the cable channels, especially more channels do not close the existing water, as this to avoid karatyang not visible after the installation of sheet peredam.intinya not to destroy something that already exists from the manufacturer “, light Hendrik, installer of Audio Design.
Hendrik also provides tips for Somers who want to apply a silencer:
* Put a silencer if necessary, so we need to know and menyesuaikanaplikasi silencers. Is it only for limited purposes only, or indeed additional needs, as well as for car audio penghobi
* Find out first what was the dominant factor causing noise in our car taken into the cabin.
Let’s not forget to ask the experts first in terms of this additional damping applications, to avoid mistakes that make losses, both in terms of both financial benefits.
Select Subwoofer passive or active?
Car Audio September 15th, 2009
In a car audio system, to produce the correct sound should be able to remove high frequency, middle-and low equal portions, if not .. then the vote will not be comfortable to be heard. To be able to get the sound system of low frequency or bass sound then the need for a subwoofer.
Market there are two kinds of subwoofers, which is a passive and active, and generally a capable subwoofer out low frequency sounds in the range 20Hz-200Hz. However, every manufacturer that makes a subwoofer also produced with the specifications and design different. Therefore, in order to choose the right subwoofer and quality needed some way to know.
Passive Subwoofer (Regular)
Passive subwoofer is a subwoofer that requires a separate amplifier to be able to make it work, so that passive subwoofer is a subwoofernya products without any amplifiers and box.
According to the installer from the Mega Audio, nicknamed Johny Ko which has a workshop at the Green Garden office block A 14 No.50, Kedoya area, West Jakarta, in choosing a passive subwoofer (used) to see a few things first, namely:
1. Match your needs, that is here is as if the concept of the selected audio is more towards sound quality (SQ), then the subwoofer should be required to issue a bass thump and generally quite soft with a subwoofer the size of 10 “or 12″ are specified in accordance , whereas if the concept is more to the direction of Sound Pressure Level (SPL) pure is needed more than a powerful subwoofer that large, usually measuring 12 “to the beat of low frequencies to obtain more leverage to produce high value desible.
2. Note the value of the frequency response (Fs). The lower value means the better the quality is the subwoofer bass sound reproduction.
3. Sensitivity values are higher rates desiblenya the subwoofer to the voice response will also be better
4. Also with the ability to adjust the amplifier to be used to drive a subwoofer that has been owned. Amplifer with subwoofer’s ability to balance, not to power subwoofer bigger than amplifiernya capabilities. If there is a subwoofer will not reproduce the maximum time bass.
Active Subwoofer
Active Subwoofer (Active Sub) is a subwoofer that has been equipped box and amplifier, and the current active sub many models, there is a tube-shaped, box and a thin box. Of the total there are some important things that must be considered in selecting or when to use active sub like this, namely:
1. Active subwoofer with a large diameter and a large box out better bass thumper better than active sub thin and small size that can be placed under the seat. But for the efficiency of the place, you should choose a thin active sub that could be placed under the seat, kind of like this is good enough quality for the current daily demand and is very much due to simple design.
2. Select a sub output on the power of voice if you want a more powerful bass.
3. Placement (Placement) on the car must also be right because if not, the bass voice might not sound focus to the future, because it usually comes from the sub amplifier has a power amplifier current is not too great and the features are still minimal.
So practically active subwoofer more suitable for someone who is just more priority on ease of installation and placement in the car than the sound quality, while the passive subwoofer is ideal for those who prioritize a quality bass (low frequency).
In choosing a subwoofer, all kinds should seek more information about the quality of a subwoofer from a few people or friends who are experienced in the car audio field, such as audio installer. Because the sound quality could not be determined solely through the technical specifications of the subwoofer, about the taste is also very influential, and therefore listening to the sound quality directly would be better.
