　　　　　　　An addition and effect of super Tweeter

　　　　　 Although the addition of super Tweeter is carried, try on
　　　　　 a basic lecture personally, and it is the sound.
　　　　　I want to have heard and come to carry.
　　　　　a basic lecture-hearing it- comparing- since it had not carried,
　　　　　 to the reader, I thought that he could not understand
　　　　　He also became what sound to try personally too, or it was interested.
　　　　　It did and was that that I understand has experienced and experienced
　　　　　that this was uncanny.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

　　This tried thing is the following item.

　　(1) What sound does the addition of super Tweeter become with sauce?
　　(2) Naturally 20Cm Addition of D-58ES is at 10Cm Super Swan but.
　　　　How is the addition of super Tweeter?
　　(3) How does sound change with the position to place?

　　 It will get very tired, if the performance of the actually same music is listened to
　　repeatedly and compared. However, this report
　　It and if many directions can have and obtain interest to the addition of super
　　 Tweeter was considered.
　　Since it is important also for a handmade speaker, it is not a basic lecture but
　　 exclusive use this time.
　　It considered as the page.
　　It is glad if it becomes reference of the direction purchased since it is your
　　 speaker life.

　　This is the fact of the experience.

　　　　

　　　　　　Super Tweeter system GS90A

　　　　　　Fostex GS90A was used.
　　Impedance 8ohm The number of reproduction frequency bands 7kHz - 35kHz
　　Output sound pressure level 102 dB/w
　　　　　　　　107Hx146Wx158.2D Weight of 1.7kg

　　The internal organs of a network circuit and the Attenuator are carried out.
　　It can be used only by connecting with the terminal terminal of a speaker system.

　　Internal-organs network With 6 db/Oct continuation good transformation
　　Attenuator
　　Sound pressure level It adjusts by MIN 15 - 1MAX.

　　　　　　　　　　　　　　　　　　　　

　　　　　　　　　　　　a. At the time of Volume MAX
　　　　　　　　　　　　　　A signal flows like an arrow and volume does not pass.
　　　　　　　　　　　　b. At the time of Volume MIN
　　　　　　　　　　　　　　A signal passes along volume in .

　　The portion which hits volume is moved and it is in a favorite tone.
　　It can adjust. In MAX, sound becomes large at the maximum.
　　Only with a capacitor, since there is nothing, volume is Attenuator.
　　The method of is convenient. It can be said also as a kind of tone control machine.
　　When there are how many kinds of speakers, it is a level for every speaker of the.
　　It can be united and used.

　　It is this book of Mr. Nagaoka that was made reference.
　　Nagaoka Audio which Tetsuo's reason understands
　　It is from description and a stereo to AV intelligibly about the technical term
　　 of an audio.
　　What are an analog/digital one? Description of a teacher of eye is pleasant.

　　　　Cautions 1. About a sampling frequency
　　　　　　What is it in 48kHz or 192kHz?

　As for reproduction frequency, a high region is extended, so that it is high.
　On theory, are actually audible.
　It is set to one half of sampling frequencies.
　Therefore, with CD, it is 22kHz and 192kHz in 48kHz to 20kHz of halves
　of 44.1, and is 88kHz.
　Since most of 15Khz(es) and BS of BS broadcast are A modes in 32kHz,
　a high region is extended.
　It is absent. However, a DVD audio will be approached if it is a B-mode stereo.
　　

　　　The number of cautions 2. bits
　　　　　What is it in 16 bits or 24 bits?

　The number of bits determines a dynamic range. This is from the maximum
　complaints.
　It is the thing of the width to the strongest sound. A dynamic range to the
　strength of sound It says like being large.

　Specifically, it is calculable by 1 bit 6dB.
　It is 144dB, if it is 14 bits, it is 84dB and 16 bits, 96dB is 20 bit and 120dB is 24 bit.
　　　　　　　
　F range is in alike some. For this, a unit is from what Hz to what kHz.
　It is shown whether it is reproducible and it is called the number of reproduction frequency bands.

　 Sauce with larger sampling frequency and number of bits is set to a high level.

　　　　　　　　　

　　　　　　　　　　　　It hears and compares by D-58ES.
　　　　　　　　　　　　Note A level setup of GS90A is united with 2.

　　　　　A-1 CD 　　　　　　　　　　　　　　　Watanabe Sadao 　My Dia life
　　　　　　　　　　　　　　　　　　44. 1KHz 16Bit 2Ch 20KHz of Quantity Region Limits
　　Comment about A-1

　A-1 does not change strongly. Although it is weak when it attaches to an ear
　and is heard, musical instrument sound can be heard.
　Although a sir and the sound which is sounding were strong, although the
　musical instrument sound of a high region was not strong, it was able to be heard.
　As for　a drum, sound comes as . It has shifted to the whole in the high region.
　Surely the high region has changed from before. That is because a loud-sound
　region is extended.
　However, there is little change with the sauce is old and CD of recording is not good.

　
　　　A-2 CD of high bit recording 　　　Perahia　Bach Goldberg variation
　　　　　　　　　　　　　　　　　　　　44. 1KHz 20Bit 2Ch 20KHz of Quantity Region Limits

　The difference of sauce has come out about A-2. Although it was not able to think
　that the theme changed so much
　It has changed from Var5. Although the chord became thick mostly, it came by the
　 first melody here with Powerful.
　Here, sound of a piano became thick and became fresh.
　There is only an excellent recording record truly. I can think that the piano is valid.
　Surely the sound to piano changed. Not only the addition of super Tweeter
　but merit of recording
　It is related. Unless recording is good, it does not change like this.

　 About CD, the feeling of a scale of sound comes out like the good thing of recording.
　 CD is usually 20kHz.
　Since it is cut finely, although it can think that more than this is unnecessary,
　 man's ear is more than it.

　In CD, super Tweeter is not actually sounding strongly. However, if it attaches,
　it is in a high region.
　Shifting can be understood.
....................................................................................................................................................................................................

　
　
　　　　　　

　　　　It is the uncanny place of super Tweeter from here.

　　　B-1 DVD audio 　　　Miyagawa command Symphonic paradise Philharmonic Osaka
　　　　　　　　　　　　　　　　　　　192KHz 24bit 2ch
　　　　

　It seems that precision is added and, as for B-1, a musical instrument and
　a musical instrument can be separately heard just like an elaborate machine.

　loud sound - occasionally - a reverberation- remaining - this- it changed truly

　The sound of the triangle of tongue tantar of the beginning can be caught clearly.
　Furthermore, the whole of an orchestra
　A high region becomes [ sound ] strong and sound of sound is becoming thick.
　Sound of a high region occasionally like a triangle has been conspicuous freshly.
　 of sound rather than anything
　A delicate feeling is also felt sharp. It is an uncanny uncanny very intense sound of
　 super-High region.

　 If an ear is brought close and asked to GS90A, super- high sound of a musical
　 instrument is sounding intensely on a grand scale.

　Although considered as the sir in CD, what is this difference?
　192kHz is 24 bit. Although the number of reproduction frequency bands is set to
　88kHz, GS90A is to 35kHz.
　This sound of super-High region was not able to be heard only by D-58ES.
　Although experienced for the first time this time
　Sound in an orchestra shifted to the high region by this addition, and the width
　of sound spread completely.

　Furthermore, the size of a dynamic range also became uncanny.
　About super-pile low-pitched sound, it is the same as that of former. Super-pile
　 low-pitched sound is resounding on a grand scale.

　　　　B-2 DVD audio　　　　　　　　　　Stravinski Spring festival
　　　　　　　　　　　　　　　　　　　　　　　　48KHz 24bit 5.1ch

　 Although the shift of a quantity region is felt too, after hearing B-1,
　 this one does not change strongly.
　Since force comes out in an orchestra, it seems to have had a new speaker.
　However, since it is sound with a DVD audio more delicate than CD, if this is
　heard, I will not think that CD will be heard.
　Although a raw sound of super Tweeter is not intense, musical instrument
　sound can be heard strongly.

　This DVD audio understands the direction of only a front for a difference for 5.1cH.
　Since, as for the shift of a high region, the delicate feeling of an orchestra and
　a spread of sound become good, force joins music.
　The sound of the orchestra of CD has faded and is applied to a delicate feeling.
　If this hears a DVD audio
　It is feeling and how to twist a DVD audio is not known.
　　　
　 The DVD audio of an effect is conclusively higher than CD. A DVD audio
　　is super-High region.
　Real value cannot be demonstrated if there is no super Tweeter only in what
　considers reproduction from the first.

　A mode of BS is sauce with a low level in this.
　It is GS90A although about me a feeling of Surround does not change since
　rear is Nessie Jr which is 16cm.
　Although change will not be greatly felt if it is heard, the high region has been
　 heard more.
　　　　
　If it attaches to an ear and is heard, musical instrument sound can be heard.
　Although a sir and the sound which is sounding are strong, it is the musical
　instrument sound of a high region. it is audible although it is not strong

　The orchestra is shifted to a high region although touch which changed strongly
　like CD is not carried out.
　Sound iof the wind instrument of a flute or a piccolo changed and has been
conspicuous.
　Although tongue hoisar has the grandeur of a profound orchestra, a spread of
　sound is felt more than former.

　　　　

　　D-1 B-mode stereo 　　　Yan sons command Philharmonic Berlin Violin Hirari Haan
　　　　　　　　　　　　　　　　　　Shostakovich Violin concerto No. 1
　　　　　　　　　　　　　　　　　　　48KHz 16bit 2ch

　 The difference understood D-1 well this time.
　Unlike sound of DVD which is cold, a B-mode stereo is a warm sound.
　Double sound increased in loud sound with an intense violin, and it became
　a fresh sound from former at it.
　If an ear is brought close and asked to GS90A, super-high sound of a musical
　instrument is sounding intensely on a grand scale.

　In the portion of a solo of a violin, double sound increased and dreadfulness came
　out. A beautiful performance
　There is force which is listening to not but live music.

　If a B-mode stereo is heard until now, A mode stereo does not have clear tone quality.
　I thought that it was not good.

　for example, bravo of Classic- although a classic is A mode stereo
　HV classic of NHK BS

　48kHz matches DVD in 16 bit with a B-mode stereo.
　Even if sauce is important and it attaches GS90A, sauce does not become good
　 about CD average.

　Moreover, I think that the merit of GS90A is demonstrated, so that sauce
　is conversely good.

　　 Old comment
　(1) The addition of super Tweeter is effective from CD.
　(2) Sauce comes out of the effect strongly like a good thing.
　(3) A tone is changeable if usage uses not only a capacitor but Attenuator.
　(4) The addition of super Tweeter leads to improvement in a speaker.
　(5) CD and the software of a DVD audio are choosing an excellent record.

　

　　(2) Naturally 20cm Addition of D-58ES is at 10cm Super Swan but.
　　　　How is the addition of super Tweeter?

　　　　　　　　　　　　

　　　The effect of super Tweeter by the super swan

　Unit attached in the super swan FE108ESII
　The number of reproduction frequency bands Fo-20kHz
　output sound pressure level 91dB

　Unit attached in D-58ES FE208ES
　The number of reproduction frequency bands Fo-13kHz
　output sound pressure level 99dB

　Since, as for FE108ESII, the high region is extended like looking, a super tweeter
　is required.　I thought that there was nothing.
　It was actually heard, and when compared, the same result as the time of D-58ES
　was obtained.
　As for the difference in sauce, a super swan also comes out clearly. 192kHz of
　a DVD audio

　In the B-mode stereo of BS, the musical instrument sound of super-High region
　is sounding on a grand scale.
　If this is heard, it becomes impossible to detach, although it was satisfied even if
　there was nothing to this.
　
　
　Even so, when the super swan was an uncanny speaker, it was realized. Former
　 visitor although it is 10cm mostly and is surprised at the heavy low-pitched sound
　which comes out - a super swan - heavy low-pitched sound
　Although D-58ES has just the difference in super-pile low-pitched sound, the sound
　to the whole does not change a lot.
　Although a speaker will be chosen in the size of the room, it is both recommendation.

　Moreover, a bottom is D-58ES although the classification top is a speaker with a small
　super swan.
　If compared, it is only small about 8cm, and is not small.
　It can also be called the speaker which takes a place rather.

　　　(3) How does sound change with the position to place?

　The position which super Tweeter places is [ right above / of a main unit / axial ]
　fundamentally good.
　It shifts and tunes finely forward and backward than this position. If sound
　will decrease if it places back, and it carries out in front Sound increases.
　Although it thinks that the best position is different in each, it is not what
　becomes nervous.

　　　　The following photograph is an interesting experiment.

　　　　　

　　　B-mode stereo 　　　Yan sons command Philharmonic Berlin Violin Hirari Haan
　　　　　　　　　　　　　　　　　　Shostakovich Violin concerto No. 1
　　　　　　　　　　　　　　　　　　　48KHz 16bit 2ch

　 In this way, GS90A was detached 1m and heard from the super swan.
　The solo violin is located in a conductor's left at the center by the side of before
　an orchestra.
　It hears a violin from this center that it was surprised although the lead in a stereo
　was taken.
　Since it can also be heard as divided, an orchestra's is [ super-High region] interesting.
　Since a performance of a violin is the addition of super Tweeter, and it is emphasized
　here and is audible It is audible as it has dissociated.
　　　　　
　It is interesting when the position to place is changed by performance. If it is never
　the same and changes
　I think that it is surprised that change is attached to the difference in sound.
　　　　

　　 Old comment
　(1) A super swan also has the effect of super Tweeter.
　(2) The positions to place are right above [ main / axial ], and move fine tuning
　(3) How to place changes according to a device.
　

　　Basic lecture (8) and E-speaker service also explain super Tweeter.
　　For a handmade speaker, the addition of super Tweeter leads to improvement.
　　his time hears it, and it compares, and I come out and think that an effect is known
　　We recommend you to surely use.

　　 Please look at here about Attenuator used for a network, and a capacitor.
