- 2way speaker using Fostex F120A 5" full range driver and Fostex FT90H horn super tweeter with Alnico magnet both. These vintage drivers are designed over 20~30 years ago but F120A is still available. Modern FEM computer aided design speaker unit like Seas and Scanspeaks sounds smooth, clear, perfect low distortion, in comparison, vintage high efficient unit with Alnico magnet sounds straight, vivid and high contrast.
Direct heated triode single ended DIY amplifier using EH-2A3 (non NFB) is well matched.
Driver: Fostex F120A, FT90H with Acoustic lens
Cabinet: SAKAE KB10 (Rubber wood)
Low-pass filter 6dB/oct (Fostex air-core coil)
High-pass filter 12dB/oct (Solen air-core coil, Benic film capacitor)
Cross-Over: 12 kHz
System
TEAC-VRDS25
DIY 2A3 SE-non NFB
2A3: Electro-Harmonix Gold
6SL7 (SRPP Drive): Hytron
5U4 (Rectifier): Raytheon

Wow
Beautiful... I wish i owned a similar system. Im trying my best with the philips Ad1255/m7, it is also pretty good in relaxing classical music.
Those sound lovely.. in fact ima listen to it again

２年ほど前にコメントいたしましたぶんぶくと申します。

きちんとご紹介頂いていました。
ありがとうございます。
中古ですがこれから注文したいと思います。
ここ数年のもやもやがすっきりしました。
２年も気付がず本当に申し訳ありませんでした。
Anybody know the name of this song?
Why almost all the audiophiles use classical music instead of Heavy Metal (such Rammstein, Iron maiden, Halford), Alternative Metal ( such as Five Finger Death Punch or Disturbed) or Other modern music genres such as Rap or Trap music ( for example, you can use 2 Phones by Kevin Gates to test bass frequencies)?
Because I am old, I like classical music. Acoustic music clearly shows the true appearance of the audio device.
Because it will sound orrible. They need songs that sound good also with my phone
Because heavy metal { although i like heavy metal and i've also been metal drummer } sounds not as good as classical music because it's noisy and i'm not talking about this particular musical theme here but in general classical music with 20 or even 30 intruments it's way more difficult to be reproduced on cheap system
On the other hand metal music can very eazilly reproduced with a very good sound quality in any stereo unless this stereo is crappy
Of course an expensive ........waaayyy expensive hi-end system do not afraid to play metal and i'm pretty much very sure it will play it F@..ing good but with metal this hi-end system cannot expose its sound charms as it can with classical - jazz -acoustic jazz - latin - reggae
As about you my friend you can take a few favorite metal CDs and Vinyl records go to a hi-fi shop and make your sound test playing your CDs i don't believe that any hi-fi shop owner will deny you if he does then he has to be an asshole
はじめまして、私もこの真空管アンプと同じシャーシーを持っております、
まだ製作はしておりませんが。
一つお聞きしたいのですが？
ここで再生されている音源（ＣＤ）の名前を教えて頂けないでしょうか？
以前からお聞きしていますが、検索しても見付かりません。
また、どこで購入出来るかわかりましたら教えて頂けたら幸いです。
よろしくお願い致します。
こんにちは。
以前からお聴きいただいておられるとのこと、感激です。
昔のアカウントはsinnkuukann117でしたが、JASRACの著作権チェックに問題があったようで、自粛に至りました。
オーディオ機器や真空管の微妙な音色の比較にyoutubeが適当かどうかは別といたしまして、どうしてもある程度以上のクォリティーの録音、音源が必要です。違法な活動をするつもりは毛頭ございません。
これまでもレコード（録音媒体、音源）とオーディオ機器は同じペースで発展してきました。
TH-camのガイドラインを守って運用いたしておりますので、どうかご理解いただけますようによろしくお願い申し上げます。
Very Nice!!!!!
thank you very much!!!!!!
yeah, wow. I watch a bunch of these speaker videos and this is the coolest I've seen in months.
hello, another amazing video! is the fostex driver in a bass reflex or transmission or ??

ツイーターの前のフィン？整流板？は何という部品ですか？
フォステクスの音響レンズです。ナントカ１００だったような気がします。40年以上前に秋葉原でFT90Hと同時に購入しました。
@@seaslyd ありがとうございます
is that a fan making the background noise? it's ruining the true quality of the speakers.
cause of using poor mic quality handy cam.
just wondering what song you playing in this video?

+seas- lyd thanks for your reply. Do you have any link where I can find it? To buy or download? I have searched but could not find it.
+Richard Danis www.ymm.co.jp/p/detail.php?code=GTM01083100
sorry i don't know how it buy now…out side of Japan…
+seas- lyd thank you once again. So there is no way I can get this ...
@@rikarus79 I recently purchased a used record and a business card fell out. The card says: " We can obtain almost any lp or cd worldwide through our partnerships with European and Japanese record stores. For special orders contact Berkleyvinyl@Gmail.com. Maybe worth an e-mail if this track is haunting you. grin
A bullit tweeter fired into an old JBL wisker?
FT90H is nice. Japanese quality JBL?
Great build , any way that you could share the blueprint and such so others could build it?
Thanks for listening!
The crossover was developed empirically, without confinement to the traditional textbook filter formulas.
Enclosure: KB10 (lumber core high quality custom cabinets for F120A)
F120A:14AWG 0.26mH (FOSTEX)
FT90H:18AWG 0.12mH,1.0μF(SOLEN, BENIC)
アンプの出力段はエレハモの2A3ですか、いい音してますね。

お聴きいただきまして、誠にありがとうございます。
EHの2A3は、音楽を愛する全ての真空管アンプユーザーにベストマッチする高品質、高音質、長寿命の300B型直熱3極管です。従来の2A3とは上位互換性があります。
増幅素子としての直進性に極めて優れた特性を備え、無帰還で優れた性能を発揮します。さらに、丈夫で安定性も抜群です。ぜひ一度お使いいただければと存じます。
演奏者と曲名を知ることができますか?

Thanks for watching.
Sorry using parts 35 years ago.
Horn lens and FT90H are vintage.
kind regards
ホテルカリフォルニアを聴きたっかたなぁ…
Excellent job, and stunning driver. I never seen before this kind of high frequency speaker. Is similar to Heill, but the sound is better, more accurate. Can i ask you to watching my video..?. You can found it as: 'My audio system - Nome in codice: raptor'. Thanks and have a good day. Paolo (Antonella is my wife).
Thanks for listening! and for Antonella!
Horn lens is very old equipment. Fostex is rare.
No bass, only midrange.

This is not a techno song honk
trying to show off a speaker with music played by only one instrument is wasting the time of the listener, the speaker is nowhere forced to perform.
to read your trash comment is wasting time for me thanx lol (^^♪
are you a leisure person? of course I am. perhaps you too~♬♪
seas- lyd can't i say whatever i want? if you disagree you know what you can do...GFY!!!
You do your job.
...bitayin thin...boxy...,but still nice
...thx...for...,listening...,and watching
