Audio Car Tuning

Audio Car Tuning

Tuners Hello! Today we will talk about what many of you are passionate about and interested. This is the Car Audio Tuning and all the possibilities of putting together a music and media team with the best options and the best style Tuning. Let's start ...
The final word on the quality of in-car audio will be determined by the quality of the speakers and their proper installation. An inexpensive and simple stereo can give excellent results with a proper game of speakers and a stereo-art power associated with an investment premium will be thrown overboard if we try to connect the original car speakers or a poor quality . As mentioned earlier, one of the most important factors here are the quality of the speakers and their correct instalación.En variety of speakers as we find two main branches, uniaxial and multiaxial. The former are divided into three or four types, which are subwoofers, woofers, tweeters and media from low to high frequency response range, respectively. The multiaxial are those that integrate two or more types of speakers in one unit, as a medium and tweeter, for example, to save space and reduce costs. Uniaxial and multiaxial are available in round and oval.
Features: Each speaker type has its secrets. Some of its features below:

Tweeters: They have a frequency response of high-pitched sound, usually above 2 KHz (Kilo-Hertz). Rather small and light, between ½ and 2 inches, and do not require high power to sound strong. Their sound is very directional and must take special care in the location during installation.

Woofers: Are the speakers with the best response at low frequencies, usually below 250 Hz, 100 Hz or less when it comes to subwoofers. Require high power to give a high sound volume and move lots of air to the sound, which requires that the set up is necessary to provide boxes or holes in the window to take advantage of the trunk itself. Its dimensions are usually from 8 to 18 inches. They are responsible for highlighting the rhythmic beats sound more serious.

Media: They have a frequency response, size and intermediate consumption. They are best answered in the frequency range of the human voice and musical instruments.

Crossover: Also called crossover. This device is capable of dividing the frequency ranges of power output or the stereo so that each speaker reach only the signals corresponding to each type. In some powers or stereo and even multi-axial speakers are integrated components, although there are also independent, active and passive type.

New Audi A3 Range will Include Four Body Styles

No comments

At this year's Geneva Salon, Audi gave us a first glimpse at the next generation of its A3 series with a sport sedan concept packing a mighty 408-horses under its hood. Now, we learn that the Ingolstadt automaker will return to the Swiss show next year with the actual production version of its premium C-segment model.

The third generation of the A3 will be lighter and more fuel-efficient than its predecessor while Audi will expand the range to include more variants.
In an interview with German magazine Auto Motor und Sport, Audi’s chief designer Stefan Sielaff said that the company's answer to the BMW 1-Series and the upcoming Mercedes-Benz A-Class will “clearly be recognizable as an A3".
This means that the new model’s design will be an evolution of the current model, adopting the brand's newer styling elements such as the six-point front grille.
Sielaff stated that the company is investing a lot in the new A3’s “precision and quality, so that the customer understands what he spends his money on.”
The new A3 will be the first model to be based on the VW Group's new MQB modular platform architecture, which will underpin a variety of models ranging from the Polo to the Passat. The new platform is designed for transverse engine application, but is flexible enough to be used in cars that vary significantly in size.
This flexibility will also be applied to the A3, which will be offered in four body styles sporting two different wheelbases. Apart from the three-door and convertible models that will measure 4.26 m in length and feature a 2,595 mm-long wheelbase, the A3’s range will also include five-door Sportback and four-door sedan models, both with a 2,630 mm-long wheelbase.
“We have basically created two couples, similar to the Audi A4 and A5 range”, says Sielaff. “The front end will be identical in all four versions, but the sedan and convertible will have wider wheel arches and slightly different shape to the side panels and rear lights.”
Sielaff also reveals that the interior of the A3’s production version will be identical to that of the Shanghai Motor Show's A3 e-tron concept sans the white leather covering the dashboard. Its main features include the four round air vents, the wider center console with the integrated MMI multimedia controls and the pop-up screen at the top of the dashboard.
The all-new A3 will be around 10 percent lighter than its predecessor and among other powerplants, will get the VW Group's new 140HP turbocharged 1.4-liter TFSI engine with a cylinder deactivation system that enables it to work on two cylinders on partial loads, thus contributing to the new model’s lower consumption.
With less than six months remaining before its official launch, the A3 is practically ready. Sielaff, however, ends with another revelation concerning Audi’s plans: “We are currently working on the TT successor, the new Q7, the R8 successor and the next A4/A5 family.”
