Handmade speaker basic lecture �H
　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 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.

　
(12) Introduction of audio accessories
　It is introduction of accessories. I a rack, a speaker cable, etc. actually
　What is being used is introduced. If it carries out handmade [ of the rack ]
　it will become full-scale.
　Better . Please make by all means.
　What goes into a hand about a plan now can be purchased from the acquisition
　method.

　
　
　(1) A rack is important.

　The audio rack of Mr. Nagaoka design
This rack can be made from itself, if you look at the following.

　The high-class rack is sold. However, a price is so expensive that it is surprised.
　There are the 80,000 to 100,000th place and 30kg - 40kg of weight with three
　steps of plywood as an example.
　
　For a tone quality side, it does not think and the rack often sold in the
　supermarket etc. is also a deer.
　Board material is the structure called flash , and inside has become a cave.

　this - being also unsteady - there is also and intensity is insufficient Naturally
　weight is made lightly.
　It is. Let's touch, when it drops in at a supermarket etc.

　Since a bad influence comes out in respect of tone quality, please do not
　purchase such a rack.
　It is because a board vibrates and it has a bad influence on equipments.

　Please [ clinic / AV / on which basic lecture (10) money is not spent ]








　* How is it in handmade?

　 Since board material is the China plywood, do not those[ with a problem ]
　 it at all. It is height to its own equipments in it.
　It is alike. I made two racks of Mr. Nagaoka design.

　The photograph on this page is this rack. Height an AV amplifier rather than
　a plan
　Since it was, the plan was changed. Others are completely the same. It is a
　plan to graph paper.
　It entered.


　　　By the design of Mr. Nagaoka, a lower plan is used by Mr.Nagaoka"Way ship"
　　　
　　　　/good for weight / strong / sound - we recommend
　
　　　　 you to make this himself
　　　　　　　

　　　　　　　　Please look at the following drawing.
　
　　　　　
　
　　　　　　　　　　　 Use 21mm thick 910×1820mm board plywood.

　Since two 21mm board material is piled up and intensity does not have an
　 enough door or back board, either, it is a code.
　Connection is easy. When piling up, this which is not pasted up was actually
　done and was felt.
　It is [ being convenience and ] better also for sound not to paste.
　　　　


　　 How to make

　　　　　21mm 910×1820mm board China　plywood,
　　　　 China runbar core material, a bond, a paint
　　　　　
　(1) Examine how many it makes with the number of its own equipments first
　 or whether height suits.
　Neither width nor depth is those[ with a problem ]. The somewhat larger
　 one is convenient.

　(2) the case where it is made a three-step pile - the upper row of - 21mm
　　- thick - make from one sheet and put into the middle
　That is, if it piles up, it is made to be set to 42mm.
　It will be set to 84mm if a thing like a is made and piled up.

　(3) It is cautious of the above mentioned and is a board to graph paper etc.
　　Let's and enter.

　(4) For the price of 21mm of China plywood, since it is one-sheet 6,500 yen
　 grade, a fairly good thing is at a low price.
　It can make.


　Moreover, intensity will become weak if it is 15mm plywood. Practice which
　makes a handmade speaker
　How about serving?


　The detailed thing of board material should look at basic lecture (1).

　It will become the cut of plywood if a plan is made. Although plywood uses
　a cutter
　Individually, it becomes difficult work. It is asking the craftsman who cuts
　 special material.


　
　　　　　
　It is good also for sound handmade and a convenient rack is made in abou
　 one week. Former
　All the methods of are satisfied.

　(5) Use no nail. It assembles only with a bond. Moreover, dirt and a crack a
　paint Since it stops sticking, let's use it.

　I applied in Washin wood-carving oil, and finished with urethane varnish.
　Moreover, a rack.
　If the same paint as - car is used, the balance of the whole room is good.

　* How is handmade [ of a rack ] in front of handmade [ of a speaker ]?
　The rack which places equipments, such as amplifier, is different in respect
　 of tone quality. This rack
　It can be made easy to use heavily. By all means, please paint and finish
　beautifully.






　　　
(2) Speaker Cable Which Changes Sound

　　　Speaker cable

　 A price can also make [ sound ] a handmade speaker at a low price well.
　 However, a rack and a speaker
　It is an important thing indispensable to accessories, such as a cable, for
　a good sound.



　The speaker cable of 100,000 yen connected especially directly from amplifier
　is carried out 1m.
　There is also a what 100 yen thing.

　 An important thing
　
　(1) Use required sufficient length.
　If too long, it will become the antenna effect, and if short, a cable will vibrate .
　It is good for sound to change into the state where you make it crawl on a floor.

　(2) Use a strong and heavy thick cable.
　It will become thick if it is 4mm - 7mm grade in an outer diameter. A maker also
　sells mostly.
　Since it is carried out, please actually see or check in a network.


　5. 1Ch, Cable is Balance of Sound, if it Unifies into the Same Maker Make.
　Looks become good. I have unified into the monster cable.
　Internal wiring of a speaker needs to solder to a unit and is a code.
　を使います. A code is made into black and white or color exception in 1.25mm
　parallel code.
　Since distinction of + and - is attached, the code which is is convenient.

　Structure of a cable
　　　
　　　　　　　　　　　　

　 The speaker cable which I am using
　The bottom is a monster cable. The red tape is attached to +.

　　　　　　　　

　　　 Monster cable
　　Above -> XPHP (outer diameter 4.0mm 2.0mm 700 yen/M
　　Below -> NMC (outer diameter 6.0mm 2.5mm ) 1,000 yen/M








(3) Beautiful Digital Cable of Image of Sound

　　　　　 Audio Ｔechnica ART LINK square shape light plug

　It is pliant and they are software, a titanium combination sheath, and a material.
　Since it was beautiful and sound was good, it purchased .


　　　　　　　　　　　　　　　
　　　　　　　　　　　　　


　　　　 Audio Ｔechnica D terminal video cable AT-DV37V

　Highly minute quality of image is faithfully reproduced by hybrid of PCOCC+Hi-OFC.
　It is D4 terminal. A cable is the portion of a terminal although it is thickly solid.
　Structure it cannot be said that is strong is carried out.

　Although light is also so, since Sawayama of accessories is unnecessary, it is
　a high-class type.
　There is [ no disadvantage end ] to buy it. A good thing can also use sound
　 long well.
