【 Weak current College 】 loudspeaker setup basic---Power By 【 China power house network 】
Earlier <br> reader received a letter signed by Stanley, pointed out that the magazine has never been articles in a matter of explaining speaker positioning. .Indeed, we never really play the Hi-Fi on this fundamental issue for a detailed explanation, therefore, the following speakers will talk to the guy anyway, the beginning of the Basic Law! <BR> <BR> Ear to do the first level .<BR> <BR> tweeter speaker that the speaker or speakers (domestic terms), it will be the most broadly divided into two major categories. .First floor-type, one bookshelf, bookshelf or floor no matter, and anyway, are not very different approach. .First, the bookshelf speakers to take a stand 』『 only Liangsheng that it is inevitable, but also some floor speakers need to take short frame; such as B & W is 801 and 802, etc.. .The speaker height, for whatever frame 』『 take it or not, in general sufficient to ear level when seated listener treble prevail. .However, this problem is not only a speaker, also need to match the height of seat. .For example: If a speaker Road, Unit 27, designated to be supplemented with "high tripod, use a high after their treble level 37" then, if you listen to when you sit down with the seat so that when the height of the high level of ear .to or less than 37 ", and that will affect the normal effect, this will make the unbalanced low to high school. As for the beginning of man, the most obvious disadvantages to see lies; if the tweeter is below ear level, .sound field as a whole will become low. If the above ear level, will be covered in the bass treble and bass to form a lack of bass, treble too much, or have the illusion of a higher sound field, but with the positioning statement as a result of bass on .cover treble effect, become blurred. <BR> <BR> However, the above is not the golden rule, there are many examples of non-general to the design of individual speaker set, like MartinLogan, Magnepan speakers such as screens, or Bose .The Direct / Reflecting speaker technology, can not set the height of the above criteria apply. In addition, some giant floor loudspeakers placed too high above the tweeter, for example WilsonAudio the GrandSlamm, or as DvnaudioConsequence the tweeters were placed close to the ground .will be based on the instructions of the designer, to a distant listening 』『 stroke distance, to synthesize a balanced Frequency response of the whole. So, no matter what type of speakers to be set must first refer to the manual, see .There is no factory guidelines it is highly recommended to program. <BR> <BR> Speaker put the first 1 / 3, listening to chairs on the second 1 / 3 <BR> <BR> good! When completed .a high degree of set guidelines request, then we must deal with the left / right channel speakers between the two, between the speaker and listening position, and the back wall and side wall of speakers such as with the speaker distance. <BR> <BR> traditional .to say, whether a new place to re-set in a pair of speakers, or for a pair of new speakers, the first step; should listen to two speakers on top of one third of the length. to 25-foot great publication Hi .-Fi room, for example, speakers from the speakers to the back wall, 8'4 "(panel from the date). .Second, the left / right channel speakers from the two to the panel axis authentic, at least 6 feet, which is effectively a three-dimensional sound field showing the shortest distance. .Too close to it, will end up the most simple left / middle / right positioning effect becomes difficult to distinguish. .In addition, the two speakers of the panel should be completely parallel to the back wall and side walls each with a 90. . (Right angle), and several feet from the wall. .As for the listening position, you should set another one-third above the speaker and listening position as the length between the two will listen to divide into three equal portions of thecut-off point. .<BR> <BR> The traditional practices, such as the publication that solely to the two ideal-type 』『 rectangular Hi-Fi room, and the terms of the traditional style speakers. .The event of irregular diamond-shaped Hong Kong's common room, or a total area of more than a thin edge off the big-foot dining room, they can only play with half of the Hi. .Fi situation, and if the use of NHT class panel tilted to the inside back wall of speakers and in particular near the NaimAudio speakers only Liangsheng, such as the traditional approach of just simply can not get the desired effect. .So the above and continue down to provide guidance for the beginning of man, the same golden rule should not regard it, as long as close as possible to the conditions they is! <BR> <BR> Basically, the back wall of the left and right speakers should be parallel to .the left and right channel speakers and speakers from the back wall of the same, while the left and right channel speakers with the listening position should have the same distance, so that the left and right speakers can ensure that any direct sound arrives at the listening position the same time, so, .speaker and listening position should form an equilateral or isosceles triangle. .If an isosceles triangle, the side of the two speakers with the listening position as the bottom, to form an acute triangle is better. .If the words were obtuse triangle, the first point and the two speakers to listen too close, or too much distance between the two speakers, too wide, in both cases, the sound field will be very easy to end up like the odd Central Results .large. .For example, a soloist of the lip, across the left and right speakers, a more extreme left and extreme right can only have two location, this is called the effect of large headphones! Like listening through headphones as the two-channel stereo playback, only the center of the skull .of a human voice, and the extreme left far-right music, feeling completely not to mention three-dimensional stage. .So be sure to properly engage the back wall parallel to the speaker before the triangle, otherwise difficult to have normal Liangsheng! <BR> <BR> Adjust toe-in angle to the intermediary three-dimensional acoustic imaging and engage in proper triangle <BR> <BR> .relationship, and then to deal with is the Toe-in problems. .Set speaker at the beginning, should be placed flat. .Ie (* Toe-in or Toe-out), this should be the same approach. .Then find some people have a certain sound recordings in the central; just like the recent large hot "Voices" gold plate, try Track2, can listen to the voice of Rebecca at the central junction as, if not, there are two possibilities .First, the distance between the two speakers is too wide, it will first horn near the central Yi. .However, if less than six feet away from the two speakers, this is a Toe-in angle, we can be two speakers bit by bit to the central Toe-in, until it can create a clear central node as up. .At the same time we must note that the sound field on both sides of the instrument sounds or other sounds, will reduced between the two speakers, or even curled up, if this situation occurs, then the Toe-in too much, too close so the sound field .narrow, so we have to use two or three different kind of sound authentic, and ultimately to achieve the sound field left, three right-average distribution of energy as much as possible, if the sound field can be much the same time hold the two outside, of course, .better! * (Toe-in, that is almost two speakers in the original ground to the inside of the turn, so that baffle even for middle between the two speakers, and Toe-out is the opposite.) <BR> <BR> .In addition to Toe-in/out perspective, the two speakers also on the sound field from the left, the right of the average distribution of energy, have a fundamental impact. .If the environment to allow both the distance betweenthe left and right channel speakers more than 6 feet, we should try the same time to the outside speakers will be equidistant to the two out, see if you can pull wide sound field without affecting the average distribution of energy. .Circumstances permit, be bold and more dollars out of the ulnar, pulled a gap in the central sound field came to a halt. .Then came the two sub-speakers closer, then again until the sound field units, until the average. .Narrow width of the case are constantly repeated pull test, and narrowed the range back and forth each time, until the program booklet to find a sound balance between the widest and the energy and the distance. .In fact, many enthusiasts will for the sake of a wider sound field and pull the left and right speakers too wide, and leads the central fault of the sound field without knowing it, so pull back and forth above the narrow width of repair procedures is extremely important. .<BR> <BR> However, there is something else must be noted that changes in the two speakers from the angle with the Toe-in/out affect the relationship with each other, therefore been engaged in any one office, another chance to do a great need for further regulation .Many more to come when many times back and forth. .Ultimately, it can not be lazy to Liangsheng! <BR> <BR> Speaker and the back wall and side wall and then to talk about the relationship <BR> <BR> back wall of the relationship between speaker and speaker. .Maybe a lot of novices will be heard, the more speakers placed close to the back wall, the more bass fullness, the more powerful! Indeed, the more abundant the nearer the more strong, but the beginning of a strong man not to ignore because of the pursuit of balance, blindly speakers .pushed too close to the back wall, which will make the low-frequency over-projection, so that high frequency has been overshadowed by other, lost balance, apart from those who will become only the amount of bass without the bass line opacity. .Therefore, the market except for a few, such as the back wall stickers placed NaimAudio specify, the vast majority of speakers should maintain a certain distance with the back wall. .As for how much distance there is no certain criteria, according to the different speakers with different co-ordination with the environment fixed, as circumstances permit, may be back four feet from the back wall as a starting point, but the reality of the living environment in Hong Kong for the past .to two feet since they have to accept. .Then repeat them to move patient before or after pulling up to a point to find out the most balanced sound. .Of course, if both can achieve stereoscopic depth and layering, it is true a good thing! <BR> <BR> Finally, we need about the relationship between the speaker and on both sides of the wall. .This is difficult to generalize, so long as the close is at least two feet away from it! If five-six feet, of course better. .In addition, common side living and dining rooms to play the Hi-Fi in the situation in which one side is the speaker of the two feet outside the walls of the same time, on the other side have to be extended to eight, nine feet to the side wall of the dining room only. .This was a compromise, only the far side of the speaker from the wall, try a larger Toe-in angle to obtain more direct voice to the phase to see if we can adjust a more balanced effect. .<BR> <BR> Speak above for reference, in fact, put speakers also involves many complex variables, such as floor, ceiling, walls, furniture, decorative effect of sound absorption and reflection, as well as bring the proportion of space size .effects of room acoustics problems. .But these would be too complicated for novices who, or who engage in these basic skills properly before going to delve into it! <BR> <BR> Have to mention, engage in anyway, apart from a small accessories is essential, .is the nail foot, regardlessof whether the original nail attached feet, we need to nail horn pad feet, swollen or bass, treble and vocal unclear, imaging and fuzzy, the sound field is also greatly reduced aspect! if .speakers do not nail your feet, which had lackluster performance! So, even if only several tens of dollars "Hi-FiTips" copper nails effect can also have back from the dead! Remember to nail feet indispensable! <BR>.
