High-quality speaker system - the transmission line speakers.

OF: Eric Source: Network reproduced Hits: 5685 Update Time :2006-1-9 15:33:54 how not a big issue of the monomer to a satisfactory low frequency, I think design is the ideal transmission .way. .But because the speaker structure is complicated, so few people try to create. .This description is an author of 8-inch woofer design for the main test for the DIY person for the results to ensure a pleasant surprise. .Dimensions as follows (Figure I for the low speakers, Figure II for the high speakers): Figure I Figure II  the timber for the HDF (high density board), the general speaker box is MDF (medium voltage intensity plate), the front baffle is 2 .6 points of the HDF bonding, and the rest use 6 points HDF. .The design for the high and low speaker speaker separation, the reason is to high flexibility. .Reason 1. In the high speaker volume, low cost, like it can do several different types of monomers loaded and enjoy a different sound. .Reason 2. Want to get a good sound, speaker placement is very important. .Bass speaker and the back wall, side walls will change the distance between the frequency response directly. .The speaker will affect the high-frequency sound field depth, positioning, and so speaker stand can be placed in separate high speakers to identify the most appropriate for low and high frequency position. .(Speaker to correct positioning, the author intends to do in the next article for a detailed description, to ensure more effective than for equipment, please look forward to.) Speakers used in products VIFA monomer, of course, you can choose similar products .alternative, such as DYNAAUDIO, SEAS, SCAN-SPEAK, PEERLESS and so on. .Use the following monomers: woofer with 8 "long-stroke single, VIFA number M22WR0906. Alto monomer with 5" cone monomer, VIFA number C13MG0908. .Tweeter with 1 "aluminum monomer, VIFA number D25AG3506. See more information on the monomer three, four, five. The author intends to use electronic crossover way, so the first single frequency network on the outside, so .can be removed at any time. inductor frequency capacitance of the network is not easy to obtain, to Xining, the reader can find good quality electronic Plaza ready to three-way crossover, a number of sound-absorbing cotton Shunpian Mai, speaker terminals back. making speakers, .I remember on the first nail on the white plastic and then to ensure that all the joints where speakers completely seal. backplane first not to nail, because sound-absorbing cotton to fill in, and finally back on the white glue and nail. the speaker also denotes compulsory .full of sound-absorbing cotton, the use of a single convex basin Alto, this step can be omitted. Figure III Figure IV Figure V   speaker terminals monomers and by physical dimensions of holes to cut the best, if something can be smaller .Files can be repaired. such as the production of any doubt please contact us: E-mail ˉ ericson@vtcinet.com meeting note: the next speaker is best to increase the low pin nails. exterior veneer types of preferences to choose the color Keyi. To direct high speaker .on the low speakers, use speakers as special fixed plastic bubble gum, or a thick sponge pad. If using ready-frequency network, or to choose monomers, the efficiency may be different due to a single one should be self-adjusting treble .monomer before the body and the tenor resistance..
