初めまして。
レストアの塗装等仕上げは最高です！
しかし、なんかスピーカーの置き方が反対ではないですか？？
世界のJBLフリークがこれを見たら、日本人の知識の浅さを露見させてしまっているようで
悔しいので、何とかこのセッティングの理由等を記載していただけませんか？
初めまして。好評価ありがとうございます。4311レイアウトの天地が逆ではないかという疑念でしょうか？もしも、この12インチドライバーが真のウーファーであれば、確かに現在の位置関係とは逆の方が帯域合成に優れるでしょう。しかしこのドライバーはウーファーではありません。
まず前提として4311に用いられる標準純正ユニットである2212を便宜上ウーファーと呼んでいますが、実はJBL D123を始祖とする「フルレンジユニット」なのです。また、マルチウェイ構成で成立するようf0を下げる工夫として質量を伴うコーン塗布剤・アクアプラス処理が施されてはいますが、4311のシステムとして使用する場合でもクロスオーバーフィルターの類は一切介在せず、アンプから直結ダイレクトに全帯域信号が通るメインユニットであるわけです。
つまり指向性が高い中高域成分のエネルギー分布は最もこのユニットに集中します。一方、スコーカーとツイーターは拡散性が高く指向性の低いペーパードームコーンであることに加えて各々コンデンサー1個（8uFと3uF）の一次フィルターでハイパスさせた、中高域エッセンスをそっと添えているに過ぎません。ゆえに、この12インチドライバーが上部配置、リスニングポジションのより耳に近い位置へ底上げされていることで、かえって音像結合は自然になるわけです。そして、標準2122の代わりに今回インストールした動画に登場するカスタム版D131でさえ、わずか0.013mHのコイルをシリーズに噛まして（ローパス目的というよりも位相特性向上のため）いるものの、ほぼ全帯域通過します。
結論としては聴感上において、より自然に帯域合成が成され定位がまとまるのは、フルレンジドライバーが下部にレイアウトされ始める4312時代からであっても、むしろこの4311スタイルへ配置変更することなのです。なぜならば、3wayスピーカーと称されながらも実情は「フルレンジ＋2」であり、低域のみならずヴォーカル領域である中高域までもが主役であるこのドライバーに集中するからです。スコーカー、ツイーターとのレベルマッチングもそれらを脇役として控えめにすることが、理想的な点音源に近いまとめ方ということになります。
よく、このユニット構成のレイアウトヴィジュアルからのみで早計判断し、「ウーファーが逆さまに配置されている」「スタジオ用スモールモニタースピーカーとして上部へ設置するためだけの天地逆構造だ」という、誤った認識をされる方がいますが、恐らく、JBL 4310を起点とした431Xシリーズの成り立ちを深く正しく理解できていなかったり、徹底した良否比較での実地経験が浅く、浅慮のまま、ただ空論をされているだけかと存じます。もし周囲にそのような方がいらっしゃれば、ぜひ伝えてあげてください。
Nice to meet you. Thank you for the positive feedback, is it your suspicion that the 4311 layout is upside down? If this 12 inches driver is a true woofer, it would certainly have better bandwidth synthesis in the opposite of its current position. However, this driver is not a woofer.
First of all, the 2212, the standard factory unit used in the 4311, is called a woofer for convenience, but it is actually a "full-range unit" originating from the JBL D123. Although the 2212 is treated with Aquaplas, a mass-added cone coating agent, to lower the f0 so that it can be used in a multi-way configuration, when used in a 4311 system, it does not involve any kind of crossover filter and is the main unit through which the full bandwidth signal is directly routed from the amplifier. This means that the mid- and high-frequency components are highly directional.
In other words, the energy distribution of the highly directional mid-high frequency components is most concentrated in this unit. On the other hand, the squawker and tweeter are only gently added mid-high frequency essences that are high-passed by a primary filter with a single capacitor (8uF and 3uF) each, in addition to a paper dome cone with high diffusivity and low directivity. Therefore, the 12 inches driver is placed at the top, closer to the ear in the listening position, which makes the sound image coupling more natural. And even the custom D131 that appears in the video installed here instead of the standard 2122 has a 0.013mH coil in the series (for phase response improvement rather than low-pass), but it passes almost the entire bandwidth.
In conclusion, it is this 4311 style arrangement, rather than the 4312 style, that allows for more natural bandwidth synthesis and localization in the listening experience, even after the 4312 era, when full-range drivers began to be laid out in the lower part of the speaker. This is because although it is called a 3-way speaker, it is actually a "full range + 2" and not only the low frequency range but also the mid-high range, which is the vocal range, is concentrated on this driver, which is the main driver. The level matching with the squawker and tweeter should be kept moderate, with them playing a supporting role, which is the ideal way to put together a near point source.
Some people often make hasty judgments based solely on the visual layout of this speaker unit configuration and incorrectly believe that the woofer is placed upside down or that it is an upside-down structure for the purpose of installing it on top as a small monitor speaker for studio use. However, I believe that they are just making blanket statements without any deep and correct understanding of the origin of the 431X series, starting with the JBL 4310, or without any practical experience in thorough comparisons of the pros and cons. If you know someone who would fall into that category, please let them know.

詳細のご説明をありがとうございます。
小生、本機の設計時のメーカー思想等の知識には乏しく、スタジオに置かれている動画や写真から伝わる認識から、
おおよそ耳の位置にツイーターが来るようなセッティングがベストとの理解をしておりました。
したがって、上下反対なのでは？といったコメントを記載させていただいた次第です。
部屋の床の反射にも因るとは思いますが、本機でセッティングをおこなう際はリスニングエリアに向け仰角をつけ
ていくか、横にして使用が良さそうですね。

ご質問くださったことで、実際の製品を取り扱う立場の見地から、正しい理屈と使いこなしの実際を発信することができてよかったです。
Tweeter is not bad, tweeter does a good job and enriches the musical expression.
Beautiful restoration ! Almost a piece of art !
Simply stunning! That sax sounded sweeter on that tweeter! I'll be looking for more as always Kenji!
Beautiful in appearance and sound as always. Good work, Kenji.
Would love to hear a A/B sound test, original vs this moded 4311... This sounds fabulous top to bottom ...
Love the burly veneer and the burgundy grills, match perfectly.
Oh, the lovely 4311 sound come back. Wonderful.
To nema veze sa zvukom 4311....ovo je uzimanje velike količine novaca za nekakav diy zvučnik
I love 🥰 this channel and your dedication to your work.
Thanks for English language offering. I also build JBL “remakes” and enjoy seeing these videos.
Are you here in the states ?
Yes… but I should say, I only build for my own use, strictly a hobby. Have a 4333 clone, and preparing for an L-65 similar clone next.
@@briansilcox5720 Cool Brian but do you know of any place I can have my speakers rebuild I live in SE Texas.
I use Upland Loudspeaker Service in California for driver repair or recone, remagnetization. Ken Haer is pretty well known, but has a very long waiting list. I have seen a TH-cam channel called texasound, you might inquire there. Almost any reputable speaker repair can recone a JBL driver,if that is all it needs, as the parts are widely available. Also try Google for JBL recone.
Great work, congrats!
すばらしい👍
How can i order or buy your speakers? Each time i look at your website everything is sold. I dont mind waiting but i dont know how to order. Thanks!
Currently all the speakers are totally build-to-order and you can place to order via email to info@kenricksound.
こんな色っぽい音色でなるのなら1日中聴いていたいと思います配信者の中で最高の音質と選曲です
音が生きてる
こんなシステムを手に入れたら早起き確定だな
Un sistema di qualità. Peccato che per farlo suonare, come riesce nella sua massima potenzialità bisogna ascoltare musica "specifica".
Sarebbe più convincente mettere, ad esempio un pezzo di Selling England by the Pound e sentire il risultato.
Provare musiche non specificamente destinate agli "audiofili".
Io farei così perché il risultato sarebbe eccellente. Ciao da Roma.
BEAUTIFUL!!!!!
Wow! Those Pioneer HPM 1100's... Please demonstrate them some time THNX!
As always , exquisite.
シルバー単線のスピーカーケーブルは単独で販売される予定はないのでしょうか？ 音質向上（というかスピードのみならず音の厚みや豊かさ醸成）にかなり貢献していると推測いたします。シャークワイヤーのサーキットケーブルなどは自作タップ内配線などで使用実績ありますが、まだスピーカーケーブルは試しておらず興味がわきました。かつて細井さんのスタジオで試聴させていただいた経験あり、もう6年くらい前と思いますが、その圧倒的な音量と表現力に感動したのを覚えています。
ワイン片手に、皆様贅沢なひと時をお過ごし下さい、的なやつでしょコレ
Một cặp loa rất tuyệt vời ❤❤❤
Nice mine don't sound like that.
소리가 좋네요.👍
이 스피커는 일반적인 스피커와는 조금 다르네요. 베이스가 위에 위치하고 트위터 아래에 위치하는데, 이렇게 스피커를 디자인을 한 목적이 있나요?
그 이유에 대해서는 이 동영상을 보시기를 권해드립니다.

Why didn't you put a better tweeter?. greetings
Are you making your own vacuum tube amplifiers now?
That’s not totally original own amp but modified one.
@@KenrickSound Oh, I see. I thought you had developed a line of vacuum tube amplifiers and diversified to encompass not only loudspeakers, but amplifiers as well.
Акустику нам демонстрируют прослушивая музыку с бедным динамическим диапазоном. Это джаз и классика, а хотелось бы послушать нечто иное. К примеру послушать на DVD-Audio -"1812 Увертюра", П. Чайковского. Но, боюсь, что эта запись повредит аппаратуру. Такого экстрима наверное не нужно. Но, что "попроще" хотелось бы.
左側のスコーカーが外されてるスピーカーの今後が気になる・・・・
White cone, m-m-m-m!
Вы уверены в том что твиттер дует в ноги это правильно ?
It feels like you're listening upside down! Sorry !!! A subwoofer on the floor will fix the scene.

Some people often make hasty judgments based solely on the visual layout of this unit configuration and incorrectly believe that the woofer is placed upside down, or that it is an inverted top-to-bottom structure for small monitor speakers for studio use. However, I believe that they are just making a blanket statement without understanding the origins of the 431X series starting with the JBL 4310, or without having enough hands-on experience in a thorough comparison of the merits and demerits. If you know someone who does, please tell him or her.
Our hearing determines the outgoing sound reflected from the surface of the Earth! The longest-lasting ones are the lower frequencies, the high ones quickly fade out being absorbed by the mass. Therefore, high frequencies propagate only through the air, above the surface and not far. You can use the bass on top as a complement to the bottom! That's what Westlake does. adds thunder and lightning! There is another solution - it is two-centric, like Tannoy.
Tweeter is bad
