Between "tweeter" and the "Woofer"

Acoustics - the most important link in the automotive audio system. That is it affects the sound quality, so if the budget is short, it is better to save on the head unit, where a considerable part of the cost falls on options, many of which are used to put it mildly, rarely. Speakers in the car must be set such that you are credible and respected by all others. We feature a speaker, and lotions hardly ever happens - are almost all going to sound. The relatively high price of the speakers, however, does not always guarantee high quality.

  One of the most common misconceptions about speakers is that the majority considers the main characteristics of the dynamics of his power, when in fact the main feature of this option is only then that he was nothing said. That is not to say, unless, for whatever method it is measured, and that the manufacturer is usually not reported. Moreover, the "maximum power" determines only that the power at which the speaker "survive", although the user is more important when it starts to wheeze, and this, too, was unreported. Therefore, you should not assume that if the dynamics of the "A" listed capacity is five times higher than for the dynamics of the "B", then listen to it could be "five times louder." The most correct method of classifying the speaker - this is their difference in radiated frequency bands.

"Tweeter". High dynamic heads, popularly referred to as the "beeper", designed to reproduce frequencies in the range from 4 to 20 kHz. In practice, this most delicate sounds - the nightingale or the gentle sound of musical cymbals. Playback frequency range is provided in such high frequency oscillations of the voice coil and membrane dynamics. Membrane "tweeter" is made of hard materials: aluminum, titanium, graphite, polyamide, etc. "tweeter" speakers are designed with the most character of the radiation of sound waves compared to other types of speaker systems and more form the stereo image in the sound picture.

  Midrange speakers (midrange). To play the frequency range 400 Hz-5 kHz using midrange speakers. This frequency range is fully perceived by the human ear and plays an important role in shaping the sound picture. Virtually any listener can easily determine the quality of the mids, so when you install "midrange" have to pay attention to their position in the cabin and focus on the listener. Typically, the size of these speakers 4, 5 or 6.5 inches.

  "Woofers" and "subwoofers". "Woofers" reproduce the sound waves at low frequencies from 30 Hz to 1 kHz, that is very loud sounds such as drums or bass guitar. Membrane "woofers" are made of special thick paper, carbon, polypropylene or Kevlar. Most "woofers" are produced with diameters 8, 10, 12 and 15 inches. "Subwoofers" can be considered as a separate type of low-frequency speaker in a special wooden or plastic box to play the lower-frequency range (from 20 Hz to 1 kHz).

  Coaxial speakers. It consists of two speakers (tweeter and midrange), mounted on a common basket. Sometimes in this construct is integrated passive crossover network which separates the high frequencies from the average. The advantage of the coaxial acoustics - is simple to install and, because of the proximity of the speakers, the exclusion of undesirable effects associated with the latency between the tweeter and midrange speaker. Some speakers 'tweeter' may be removable, and a coaxial speakers into a component. You have an additional opportunity to experiment with the installation, thereby achieve the most high-quality sound. Such systems are more expensive than conventional coaxial acoustics, so before you decide to buy speakers with removable "tweeter", we should think about whether you engage in these experiments. Quite common also triaksilnye acoustic systems, combining in one basket, three dynamics working in different frequency ranges.

  Established music systems consist mainly of the frontal acoustics - four midrange speakers installed in the torpedo and the front doors. Less cars are equipped with rear and two 5-inch speakers, placed in the rear shelf and serve as "woofers". This is quite enough for those drivers who are not too focused on sound quality, but very little for those who are not indifferent to quality. The question arises as to replace regular speaker on more "advanced". It is believed that the most common type of alternative front acoustics are coaxial measuring 5 inches. Brightest representatives of this category - the dynamics Eclipse 8253 and Farenheit MX-5250S. Of the total mass of the rear coaxial speakers can distinguish Oval Power Acoustik PSP-6932, Dragster DC 903 and Alpine SPS-6939S size 6x9 inches. The only, but significant negative of these speakers is their crossovers. There are models with high-grade coaxial frequency filters, but they are extremely rare. In most cases, manufacturers are limited to a capacitor, "filter" beeper, which makes the sound is not as clean as that of component speakers, equipped with high-grade crossover.

  Despite the large number of pluses coaxial speakers, real connoisseurs of the car audio and car audio professionals prefer component acoustics. As the size - the same caliber pyatidyuymovy available here almost more than all other formats are combined. It is believed that it was "five" - this is the best compromise between our needs and their capabilities. Not recognized leaders in this category - Boss RD -15 and Focal Polyflex 130 HS - ideally work out the average frequency in conjunction with any subwoofers or meekly assume the proportion of the lower classes in three-color combination.

  Three-band acoustics have always stood in the car audio a bit aloof, and its production, by the way, decided not everyone - as a rule, it is highly specialized "speakers" of the firm. "Standard" three-lane configuration is as follows: bass driver (woofer) with diameter 6.5 inch, midrange - "Quartet" of the same series and the traditional dome tweeter (for a given manufacturer) design and size of the membrane. The most common deviation from "standard" - is a construction of MF heads. Until recently, the midrange was similar only to "woofer" in miniature, but later appeared midrange, more reminiscent of beeper-overgrown.

  Acoustics, referring to the category Hi-Fi, as all exclusive in this world, there is their own laws. The aim of such systems is usually not so much the achievement of high quality music listening as satisfaction of someone's specific claims to the car sound. Here, everything is possible, with many controversial civil class nuances, such as the desirability of making podiums under "Tweeters" or a separate processor crossover for each pair of speakers, neobsuzhdaemoy become the norm. That's true - when an extra couple thousand dollars is not important, you can afford to put some excesses. And the quality will be affected only in the better.
