"And listening to the speakers space is one", all kinds of sounds are produced in the interaction between the speaker and listening space of two. According to the various conditions, can find the most suitable for your speaker placement in the "swing eight law".
★ three one seven ratio method: the length of the room are divided into three equal parts (three), the horn is placed in the 1/3 length (a), the interval between two horn 0.7 times for 2/3 of the length of the room (seven). Horn best slightly inward projection angle, but also no inward projection, the listening position can not paste on the wall.
Effect: this method is used for larger size, the ratio of uniform (such as 1 ∶ 1.25 ∶ 1.6 or 1 ∶ 1.6 ∶ 2.5) space, can obtain sound field balanced sound with wide deep.
★ three three one ratio method: the length of the room are divided into three equal parts (three), width is also divided into three equal portions (three), the first division point of the horn is placed in length and width of the (a). The loudspeaker can be inward projection angle slightly, even without inward projection can be, the listening position can not paste on the wall.
Effect: this method is also used in the larger space, the ratio of uniform size. It and the three one seven ratio method is the only difference is the interval between two horn is narrow. This method can get the sound field balanced sound with wide deep.
★ screw pendulum method: will the horn is placed in between 1/3 to 1/2 the length of the room, and then the two speakers try to depend on both sides of the wall (such as the room is wide is not close to the side wall), two horn inward projection angle greater than 45 degrees. The listening position after projecting angle cross intersection about 0.5 meters -1 meters.
Effect: this method is designed to cope with the soprano, Alto, bass too sharp skinny enough shortcomings.
★ equilateral triangle method: first is the horn to leave after the wall (at least 1 meters) and side wall (at least 0.5 meters). The second condition is the two speaker and listening position draw a triangle. The third condition is also 45 degrees or more two horn inward angle of projection. The fourth condition is the triangle can be big or small. The room is small, after the power is small, deltoid; room is big, after the power is large, triangular to draw more.
Results: it has the advantage of reduced the walls reflected on excessive interference horn direct sound, well positioned and wide deep sound field. This is to be able to hear the most, the most direct, the most clear details of the pendulum method.
★ long side pendulum method: the horn against the pendulum, with long edge room horn back wall, the rest of the regular triangle pendulum. The listening position can not be stuck on the wall, leaving at least 0.3 meters distance.
Effect: intermediate frequency and low frequency quantity feeling enhancement, the soundstage depth is poor.
★ diamond pendulum method: this method is limited square space. The square space as the diamond, the horn is placed in a diamond on both sides by the wall. Horn behind the lozenge pointed and the listening position behind the lozenge pointed arc or cylindrical acoustic diffusion treatment, horn should not rely on the side of too close to the wall.
Effect: this method can solve the square space bass rumble standing too strong problem. If the square space don't swing, will into the furniture to "calm" standing wave.
★ wall pendulum method: Horn close to the back wall swing, regardless of the distance from the back wall of 50 cm or 30 cm are never mind, you can prepare.
Results: high frequency, low frequency weak sharp, use frequency, can let the full intermediate frequency and low frequency, high frequency, in the whole, the balance can be. It will make the sound field depth, width. But if the sound phase and screeching trade-off, sacrifice the sound field performance and get the voice is the right approach.
★ Cabinet method: this method is designed for no small speakers use tripod. If the speaker is placed in the cabinet, to cushion the marble or granite in the horn under the pyramid, placed between the horn and stone. If the vibration absorption of iron sandbag or iron on the horn on the top. If the speaker is placed on the bookshelf, the horn upper and lower, left, right with books. At this time, the pyramid without the use of.
Effect: a sound will plump and firm, not a high frequency. At this time to listen to the sound for the first appeal, the sound field is the second.
★ three one seven ratio method: the length of the room are divided into three equal parts (three), the horn is placed in the 1/3 length (a), the interval between two horn 0.7 times for 2/3 of the length of the room (seven).
