    Handmade speaker basic lecture C

                                        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.

                  

 Introduction of the speaker of Mr. Nagaoka design
 it is easy to make 500 from the speaker of a certain Mr. Nagaoka, and an
 effect is high
 The speaker was packed. It goes into a hand about a plan now.
 A thing can be purchased from the acquisition method. It is related with books
 out of print, and is [ this ].
 Please look at E-speaker service and ask a question.

 
 (5) The speaker of 16 cm
           

The 3rd place

 
(1) SS-66 Moai

  Separate type monitor speaker
 The 3rd place of the Nagaoka speaker BEST10 which a reader chooses
       
 It designs in the form which responds to the hope of the musician K who is
  also an audiophile.
 When it is what was carried out and there was no severe order of Mr. K, it did
  not make probably. It is a speaker.

 It is wide and that it is a flat, the main, and a Subwoofer fur are separate
 four points.
 Joge -- in piles -- a floor type and the main -- Bookcase and the main
 It is orders that it can use enough, that it can drive by one set of amplifier
  etc.

 It wins a great success as a result.

A separate type is that time in a new genre also in the speaker of
    Mr. Nagaoka. It was winning a great success and was set to one of the
     popular works.

 Evolved Moai (evolution of 21st century Moai)

  SS-66 Moai by which Mr. Nagaoka was designed takes out a face with
  a popularity vote to a higher rank.
 By the separate formula of two steps of upper and lower sides, the model
 of the unit at the announcement time is changed into a new model now.
 It is carried out.

 The characteristic summarized how for how sound changes.

  Evolution of Moai
  The sound of Moaiwhich used the present unit and evolved can be used also
  as a monitor.
 It had the wonderful wide range of a degree and evolved into a speedy sound.
 The plan is using the same thing as the original of Mr. Nagaoka.

 Sound and the characteristic of having evolved

  When a new style unit is exchanged, it is large improvement in tone quality
  without making sense of incongruity hold.
 It has The exchanged unit is the succeeding model of the same Fostex.
 Therefore, the which is not considered as change of all plans although
  a thing with sufficient affinity is not wonderful, either
 having been settled firmly so far -- present -- business -- isn't it good
 news in the inner one, either?
    
  The recording monitor to which it had a wonderful wide range and speediness
  was equal all over the districts
  Even if it carries out, the sound and this which can be used are the feature
  of Moai

 This became a new style unit and was upgraded further. Especially T96 A-EX is.
 It is more fascinating and the high region which is full of a feeling of substance
 jumps out. This super-Loud-sound region
 A pleasant sensation is irreplaceable.

 Moai is made.

  If three ways are purchased with a commercial speaker, we will recommend
 you Moai.
 It is not difficult to make only because of a box. A vertical bus reflex structure
 sake
 It is making the duct of a bus reflex correctly.

 A unit, a wiring code, capacitor CS0.47micro F, and coil LS2.2mH
 Making a capacitor cheap, although it is required, CT0.47micro F and a coil are
 L3.5mH.
 It can also carry out. A reason is the newest network element, if original.
 It does not use. The conventional thing is also arranged enough.
      

  Although there is a size a height of 1m, the side is not so large as 25cm.
  Although it is a tall boy
 The view of a network element differs from the speaker of three commercial
  ways.

 A network is very simple and are a coil and one capacitor.

 This is carrying out the work which makes it simple by Nagaoka style and
  employs the sound of unit original efficiently.
 Maker make is a coil and a capacitor in a complicated network, if it is said
  [ how ] whether be.
 Since a lot is used, the freshness of sound falls.

 Since it does not make artificially, for a network, sound is simply as it can do.
 The power which a unit has by carrying out is efficiently employed in the
 maximum.

Moai is a developed type. Since it can do in the combination of a unit
     it is a back load.
     A phon is the speaker which is completely different.
 



                       
 

 
The 9th place

 
(2) D-168 Super Rare
               
 An original super rare (FE168SS use)
                
  Rare is the small ostrich which lives in South America, and Mr. Nagaoka is a
 swan. I think that it named by the large thing.

 At 16cm, the design of the back load phon of Mr. Nagaoka is super rare.
 There is D-37. The original unit was both FE168SS.
                    
             
Rare (alias United States ostrich)

  The difference in a character
 The comment of very interesting Mr. Nagaoka the sound which attaches
  FE168SS It is.
         D-37= monitor tone
         super rare = music nature


 It is both wide and they are a flat and high efficiency.
 if compared with a 10cm super swan -- a super rare one -- hard
 It is powerful and is dynamic.
        

  The breadth of 450mm, the depth of 470mm, and 全 quantity are 1130mm.
 the center of a floor to a unit -- until -- the position of the ear when applying
  to 1015mm and a sofa

 Board thickness uses 15mm and four 3x6 plywood.
 basic structure -- a super swan -- the same -- the back load phon of a rear
  surface opening
 The whole is made from a head, Pipe, a body, and three.

  Assembly
 How to assemble is a D-101S super swan because of the same structure as a
 super swan.
 Please give me. Here is explaining in more detail.


If an assembly works as the turn of distance, it will be satisfactory first.
  a whitish image [ like a swan ] whose paint is -- the method of brown finish

  It seems to be good. Although it will be teak material if it says byThurs
   a paint is good at his liking.

 (3) D-37

  FE168ES (limited sale)
 It corresponds to FE168E (unit only for back loads of the H.P. oscillating
  version).
 It is the design for FE168SS at the time of manufacture. A unit can use ES
 and E.
 It can sound with the room of 6 to 8 mats as a 16cm back load phon.

 A basic design is a slender tall boy in D-57.
      
 powerful -- D-37 completed by unit FE168SS
  The unit of the time of a design was FE168sigma. powerless on a back load
 It was not the best in a unit. The cabinet with the it same at the appearance
  of SS
 When it was alike and SS was attached, it experimented in what becomes.

 It was the sound of a special different dimension. and there is a powerful scale
 It became sound.

  How is it in unit FE166 ES-R of limited sale?
 From present FE166Esigma, since a magnet is powerful, it is in reproduction of
  heavy low-pitched sound.
 It becomes advantageous.

 Since loud sound and low-pitched sound are between 10cm and 20cm musically
  the degree of 16cm is good.
 There is the feature to reproduce.
 The room also has the merit which can fully be sounded with 6 mats.

 A conclusion is arranged enough.
 A part to have been upgraded is useful
to reproduction of low-pitched sound.



  The depth of 45cm, a width of 240mm of Speaker attachment hole, and full
  length are 1000mm.
 Since board thickness is 15mm, a reinforcement board is attached in all boards
  and intensity is a problem.
 There is nothing. The side of basic structure is the same as that of D-58 grade
 at 30mm.

  Carry out five-sheet weak use of the 15mm thick 910×1820mm plywood.
 It is the speaker which becomes main.

  The addition of Tweeter
 Loud sound will become beautiful if super Tweeter is connected only by the
 capacitor.
 It connects with film capacitor 0.47micro F or 0.68 micro F by reverse .
 Although super Tweeter is arranged by FT96H, T90A, and T925A
 the thing in this with the lowest efficiency -- FT96H -- efficiency is higher
 than it but
 We recommend you T90A.
            

* Since it is the same as D-58ES about an assembly, it is handmade
  speaker D-58ES. Please give me
 Since this is entering a manufacture process photograph, the one where
  handmade is the more nearly first is also understood.
  I consider.
