Handmade speaker basic lecture �I
　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　Masao ida
　It is a basic lecture for making a handmade speaker.
　From a beginner, please also looking-obtain maniacs and enjoy
　a handmade speaker.
　It was made the English version so that he could also understand
　overseas one.
　　
(13) AV clinic on which money is not spent

　　　　　　　　　　　　　　


　The upper books are Nagaoka of the 1985 issue of Mr. Nagaoka. Tetsuo's
　audio Clinic

　It is Clinic the audio room of audio lovers all over the country - entering
　- actually
　Carrying out clinic is written .







　I also read this book, and it carried out as actually written.

　Sound and the image changed very truly. Super-low-pitched sound is felt
　 much more, and sound is
　Inside [ the color has come out of 20% rise which comes out, and the image
　finely vivid moreover until now ]
　It was finely colored to.


　 This book can be used satisfactory even now, although no less than 20
　 years are a front.It is rather here now.
　I do not learn the method currently written and think that there is little done
　 direction which is.

　The tips on clinic are simple. It does not adhere to a not much fine thing, but
　they are foundations.
　It is carrying out faithfully. Furthermore, it is upgrade of equipments although
　it is easy to mistake.
　money- applying- a basic rack and a connection code -- it places and a stand
　etc. is important

　In order that, as for these, money may go to equipments, this is because it does
　not think.

　 It is AV clinic now. It is because it became not only in the audio now.
　At the expense of minimum, sound and an image change only by doing the thing
　 of only this.
　　
　



　(1) Put a ditch plank on the bottom of a speaker.

　　　　　　　　
　　In a Sub woofer 12kg per < concrete plate [ two piece / 1210 yen ] > piece




　　　　　　　　
　To a super swan 7.5kg per < concrete plate [ two piece / 834 yen ] > piece

　

　 A concrete plate goes into a hand in a home center easily.
　The even thing which is not round by contact to the floor is completely good.
　Furthermore, if a plate is forced on a wall, low-pitched sound reinforcement can
　be aimed at.

　which it crawls between the bottom of a speaker, and a plate -- black cloth is placed
　　　　　


　(2) Remove the plug without necessity etc.

　 The decisive cause of tone quality degradation is a pin plug without the necessity
　 for the amplifier reverse side.
　The present AV amplifier is computerized. It connects.
　A plug is amplifier to what does not have necessity since it is controlled.
　Is it alike and doesn't a burden start?

　Therefore, what is rarely used is many, although are removed and it is a principle.
　The user has tied to when or the pin code which may be used.

　Especially an AV amplifier has many connection terminals of a rear panel.
　Although my AV amplifier is onkyo TX-DS989Ver2, for a connection terminal,
　100 is.
　It is. It is because there are a digital system and an analog system and there are
　 a sound and an image.

　 A minimum terminal is a speaker terminal connected with a speaker.
　Audio optical input / output terminal
　Multichannel terminal

　Don't connect with an AV amplifier but connect an image to a direct liquid crystal
　projector.
　An analog is not connected without using it.


Since it is only this which left, only the terminal of 15 is used among 100.
　　　
　　　
　　　　　　　　
　　　　　　　　The plug without necessity is removed. Price of 0 yen





　(3) Put a weight (concrete) etc. on amplifier and a player.
　　　　
　 Put in the China plywood in between and put a concrete plate on amplifier etc.
　In this case, it is [ whether a concrete board is direct placed on the China plywood
　 and ] the China plywood.
　an insulator is used downward - also coming out - it is good

　It is the purpose that a problem prevents vibration of equipments. Amplifier etc
. is an air hole to the upper part.
　Please do not enclose completely

　As for the stereo amplifier of x former, calorific value is high. It is especially
　 a high-class model.
　Since calorific value is large, it is dangerous if concrete and a lead plate are
　carried recklessly.
　It is. A heat dissipation mouth is avoided, a board is arranged in the outside of
　amplifier, and a crevice is also left.
　Placing the whole surface on necessity and amplifier is least good.

　Although calorific value of an AV amplifier is not high compared with stereo
　amplifier, when it is me
　All A mouth with heat are not closed but it puts on the space of the half for
　 the upper part of amplifier. It is.

　Concrete has the fault that the place placed although it can do at a low price
　becomes large.
　Although it may say that a lead plate is expensive and it is hard to go into a hand
　 a space is few.

　It can do. It is an ideal to avoid several (4kg - 6kg per) exothermic mouths, and
　to place a lead plate.
　But a writer has not found it yet, either.



　　　　　　　
　　　　　　　　　　　In an AV amplifier 7.5kg per
　　　　　　　 < concrete plate [ two piece / 834 yen ] > piece




　　　　　　　
　　　　　　　　　　　In a broadcasting satellite tuner 5kg per
　　　　　　　　 < concrete plate [ two piece / 624 yen ] > piece




　(4) Rack Which Degrades Sound and Image

　 The board itself vibrates and, as for the thing using the plywood of in the rack
　 it causes degradation.
　Moreover, a heavy thing carries, and since there is no れ, it restricts a rack to
　a strong thing. It is sound by the rack.
　Dividing has much direction which is not known as it is unexpected.

　Having made this lecture into clinic has a look at the rack which he is using once
　again.
　It wants. If it can do, I will have the clinic of what he is using carried out.
　 Then, sound and an image become good more.




　The clinic of a rack is carried out.

　1. Do the front and the rear surface use the rack of opening?

　2. Isn't Board Material Structure Called 　Flash　?
　　It will sound a pompon if internal space strikes by the hole opening.

　3. It is unsteady, there is and there is no intensity.

　4. The glass door sticks like furniture or the reverse side is closed.

　5. It is what was in the house and use with the makeshift for the time being.


　It is x worst. The bad influence of these racks is carried out to tone quality.



　a good rack - tough matchless - even if it moves, so that it does not move
　　- equipments -- a rack -- heavily
　It is staying on. A rack had better have simply Shigekazu Tei who does not move.

　It is so expensive that it is surprised at maker make to fulfill these conditions.
　Maker make 80,000-100,000 is also carried out. Those who are using the rack of
　cheap for the reason
　Many one thinks the present condition.
　
　
　 A rack recommends you a its original work.

　A reason is this.
　1. It unites with the size of equipments and height and width are also united.

　2. Since the China plywood etc. is used, a budget is made low.

　3. If it applies in the same color as a speaker, a feeling of unification will come out.

　4. There is a rack with which Mr. Nagaoka was designed.

　About a rack, it is to basic lecture (9) about the rack of 21mm of Mr. Nagaoka design.
　It has carried. Please look at here.
　　　　　　　　　　
　 My rack is a rack of China runbar wood core material 21mm of a design of
　 Mr. Nagaoka.
　By the two-sheet pile, by 42mm , since intensity does not have a preeminence,
　 door, or back board, either
　It is easy. A pile accumulates and is easy in handling because of a system.
　　　　　　　　　　　



　　　　Its original work (China plywood / China runbar core material)
　 　　　　　grade of 10,000 yen - 15,000 yen of a rack

　　　　 　　　




　　　　　　　




　(5) If Sound-absorbing Material of Speaker is Reduced, Standup Will Become
　Good and Fine Sound
　It comes out well.

　Glass wool is [ whether although put in mostly, it is few recently, and ] zero
　 a long time ago.
　It is thought that is good. Since this thing is also related to degradation of
　tone quality
　What is necessary is just to do.

　The sound-absorbing material of a speaker is reduced. Price of 0 yen


　(6) Surround the surroundings of a screen with black cloth.

　 However it may be a high-class projector and a screen, the surroundings of
　a screen
　Light reflects and is not beautiful if it remains as it is. It is black cloth
　(if it can do) about the surroundings.
　When it surrounds by thicker perfect black, an image is the beauty of improving Tei.

　For an image, how to make from a relation with the room is the equipments itself
　 although it is not the same.
　The screen money serves as foundations in front of it rather than is spent,
　
　If the stand which places ー is improved, projection will change completely.

　I did handmade [ of all the home theaters ]. A screen and software are put in.
　It is in the color as a speaker of the projector which can be placed with the
　stand place and same with the China plywood.
　It finished.

　even if the mode also sets up adjustment of an image low in front of a check
　and in the back again -- beautiful
　It came to be reflected.



　* It is the super-Hi-Vision home theater updated from the home theater in detail.
　　Please have a look.

　　　　　　　　　
　　　　　? This is black cloth. A price is from the 500 yen grade per m.





　 Although there is still this continuation, today is to here.......... It is Masao ida　

　　　　
　
　　　　　

　It was how. He was able to be enjoyed.

　Making is important for a handmade speaker. An audio does.
　It is the back deep world which can be understood. 1950 to 1970 age is amplifier
　and speaker.
　The car was handmade. It is a maker the direction and recently to know these
　days and come to do again.
　Fun is not felt for and there are those to make personally.

　The speaker of a design of Mr. Nagaoka is known and it is only that the
　wonderfulness of the sound is handmade.
　It is the world which is not made.






　 It is glad if you make this homepage reference.

　(1) You Which Makes Page of Handmade Speaker, Basic Lecture, and Super Swan
　　Please have a look to the reference for making a handmade speaker.

　(2) Super-Hi-Vision Home Theater, Ultimate DVD Audio, Record Player
　Please look at to an understanding of information, the connection method,
　etc. related hard.
　　
　(3) Board Material of Speaker Which Mr. Nagaoka Designed with E-Board Material
　 Cut Service
　Cut service is offered.
　Although a speaker is natural found in this basic lecture, it is designed personally.
　It is sufficient, and if there is a plan, I will cut what [ adaptation / what ].

　(4) The purchase of a unit etc. can perform E-speaker service. Full range
　The product of a unit and other Ｆostex [ a terminal and ] is treated.

　　　　　　　　　　　　　　　　　　　

　(5) A reader's voice Q&A is carried to the question which cannot answer by mail.

　(6) This whole HP should click and read guidance of a lower homepage.
　　




　(7) The ideal of Mr. Nagaoka is a handmade home theater. "Way ship" is the ideal.
　It is the made building. I also make the home theater made with a handmade speaker.
　is very interesting.





　You also surely look at my homepage and build your home theater.
　Please carry out. And future is [ my homepage and ] also the degree of
　association forever.
　Thank you for your consideration.
