Cho em hóng hớt chút nhé.em cũng có 1 đôi 4312A,đang tính ghép với Mc7100 của Mcintosh,đang lăn tăn ở chỗ là không biết em này có kéo nổi 4312A không nhỉ.bác nào dùng qua rồi cho em vài lời review nhé.

 

Có chắc loa đời mới mướt hơn không? Chưa hiểu mướt của bác là như thế nào?

 

Em mới lấy JBL 4312B, em này khác với 4312A như thế nào?
Đánh với amly gì hợp nhất

 

"Mướt" với em là treble chi tiết hơn,âm thanh tổng thể mềm mại & không bị khô,đặc biệt khi nghe SACD bác ạ.

 

Chào đại gia đình JBL. Sau một thời gan mua bán đổi chác em đang hướng tới căp 4425,hiện tại em đang dùng CDP Teac 25x và amli Manrantz 14SA ver2.Cho em hỏi các bác có nên đổi amli Luxman 570Xs không? Hai amli trên em nào cho 4425 kêu hay mong các bác cho ý kiến để em đi đén quyết định.Cám ơn các bác đã đọc tin

 

Chào bác, 2 amply trên kg em nào làm cho 4425 hay cả, nếu bác ở HCM thì thử ghe Trí Nguyễn để nghe thử amply đèn 8W/kênh (khoảng 360$) dìu em 4425 rất du dương. :lol:

 

Mình đã có dịp ss Marantz pm14sa ver2 và L 570 đánh jbl4425 . theo m pm14sa nghe hay hơn l570 nếu đánh loa jbl4425.

 

Cám ơn bác Phúc có lẽ em giữ PM 14sa lại để đánh với 4425

 

Chào bác, trước em co 4425 phối với lux 505u nghe rất chi tiết . VỤ NÀY EM THANKS 2 BÁC THANH SƠN VÀ PUSER ĐÃ TƯ VẤN :lol: . Sau đó em tiễn em này và thay vào 4428 âm thanh còn hay hơn. Theo em thì bác nên đổi Mar lấy Lux thì âm thanh sẽ hay hơn khỏi phải lăn tăn.

 

sau một thời gian nghiên cứu lên rồi lại xuống
và cuối cùng em down xuống thật các bác ạ
hiện tại em đã có bộ dàn audio ưng ý không phải lăn tăn nữa cũng đã đến lúc an tâm nghe nhạc rồi

Không biết có bác Fan JBL nào có nhu cầu sưu tập cặp loa này không?
http://cgi.ebay.com/JBL-James-B-Lansing ... 7C294%3A50

Khoan hẵng nói về cặp loa mà nói về tay chủ loa, thực sự là một JBL Fan. Em thấy bài này đúng là một sơ lược về lịch sử JBL.

"Before there was a JBL, before the 1954 Hartsfield, this monumental speaker was James B. Lansing’s First – and Last – Top of the Line Statement Speaker … the James B. Lansing D-1004 Loudspeaker released in 1948 and was offered from 1948 through 1953 - it is literally a Time Capsule!

In 1948 Babe Ruth gave his famous farewell speech to baseball in Yankee Stadium, the first McDonalds opened for business, the first Nikon camera is released, Truman defeated Dewey for the Presidency of the USA, and the very first 33 1/3 LP is manufactured (in mono, of course). Also in 1948 James B. Lansing, the namesake of JBL, after more than 20 years of toiling in the audio industry designing and building OEM drivers and speakers for other companies finally has the moment that he has been waiting for - the opportunity to design and build his very first Statement Home Audio Speaker. This is the very first Top of The Line speaker designed from the ground up by him, with his drivers and crossovers, and assembled, marketed and sold by a company that bears his name – the James B. Lansing model D-1004 / D-1005 loudspeaker depicted on this page. Even venerable McIntosh had not yet been formed as a company at this time.

On my list of heroes in the audio industry, the top of my list is James B. Lansing. Jim Lansing started his first speaker company in 1927 making OEM parts and quickly developed a reputation as being a remarkable innovator and visionary, and an irrepressible creative spirit. His genius is not just having the knowledge of how to use innovative materials and precision manufacturing techniques, but combining this with his fertile imagination and an obsessive drive to perfect and continually refine each process. From his early involvement with manufacturing the innovative MGM Shearer sound system which won an Academy Award in 1937, to the creation of the “Iconic System” – the first true 2-way full range studio monitor which became the prototype for both professional monitors and the home audio system, to forming Altec-Lansing in 1941 – Jim Lansing was already an audio industry icon by 1946. Among his other great innovations was the Altec 802 / 902 horn, a driver that was so successful that it stayed in production for more than 50 years! In 1946 he left Altec Lansing and formed his own company - Lansing Sound. Within a year created the most famous cone driver ever invented – the D-130 Alnico V driver, a design so technologically advanced that 60 years later it is still a viable and relevant driver.

In 1948 Jim Lansing, after resolving a name dispute with his former company Altec Lansing and changing his company name to “James B. Lansing” (and later to become JBL), takes his first (and last) home run swing and creates the very first Flagship Speaker of his fledgling company – the D-1004 (and its twin the D-1005). This remarkable speaker would start his new company on the path of being the most innovative and dominant speaker company in the world, with an incredible history of more than 60 uninterrupted years of audio manufacturing production.

Sadly, Jim Lansing never got to see the incredible success and amazing inspiration and extrapolation that his genius provided for the JBL product line over the next few decades. Like many visionaries, James B. Lansing was way, way ahead of his time. While we have all benefited from his incredibly technologically advanced foresight and groundbreaking innovations; from an innovation standpoint he was miles ahead of where the market was and unfortunately all of his businesses suffered as a result of his burning desire to create and perfect and push the envelope. Although these speakers were truly magnificent and critically acclaimed, the “home audiophile / enthusiast” market was in its infancy in the 1940’s, and not many could afford the grandeur (and cost) of such a cutting edge speaker system in 1948. Few of these magnificent D-1004 systems were ever built and sold, and his company was already mired in debt at its infancy. Despondent over the course of events in 1949 James B. Lansing took his own life, and never got to see his company survive these desperate financial times (ironically with the help of his own life insurance policy), and watch as the market not only embraced his incredible vision and creations over the following years, but propel the company to amazing achievements such as the 1954 Hartsfield, which succeeded these D-1004 / D-1005 speakers as the company’s Flagship Speakers.

I am a music aficionado as well as an avid collector and own quite a few rare and exotic components and speakers from the 1940’s through the present era, and this matching pair of D-1004’s is the rarest, most thrilling and historically significant speaker set that I own. A beautifully preserved matching stereo pair built 10 years before stereo was a reality. Personally, I feel a strong sense of historical purpose to preserve these amazing 60-year old survivors that showcase the very first pinnacle of success of his fledgling company that would eventually become JBL. For all I know these may be one of the very few that still remain in existence. When Jim Lansing was hand building these D-1004 speakers, the popularity of his innovative D-130 woofer and 175 Compression horn was starting to skyrocket. But he was new to building his own speaker cabinets, his company was tiny and hopelessly in debt, and very few of these massive and expensive (for the era) Flagship D-1004 speakers sold during their production run. These D-1004 speakers are so old that the woofers all have the earliest known labels with "Jim Lansing" (the big "L" versions) on them, while the crossovers have the first hand typed, “cut corner” labels that use the "James B. Lansing" company name.


Please note that this speaker was designed and manufactured in the Mono era, almost 10 years before the advent of stereo. To be historically correct, Walt Disney's Fantasia movie was released in 1940, and they had the first ever use of stereo recording and playback (they actually recorded eight channels and played back a mixed 3-channel). However professional and home applications of stereo came many years later in the mid to late 1950's - the first stereo LP record was not released until 1958, and the first stereo radio broadcast in the USA was in 1961. Everything prior to that era was designed, marketed and sold as Mono systems - single speaker cabinets.

The original owner of these magnificent speakers was an audio enthusiast who bought the first of these D-1004 JBL speakers sometime after 1948, and had a special corner stage built to accept them in his home. He loved the sound so much that shortly thereafter he bought a second D-1004 and installed it into his vacation home so that he could always have his music with him. When stereo become a reality and the defacto home audio standard, he then merged the two speakers into a single unified “stereo” system in the early 1960’s.

The D-1004 / D-1005 speaker systems were available in only two finishes styles – model “D-1004” was Dark Mahogany, and the twin “D-1005” speaker had a finish first marketed as Vera Blond and then changed to Bleached Mahogany. The original owner bought the first one in Dark Mahogany, and then bought the second one in Vera Blond / Bleached Mahogany to match the vacation home’s décor. In the 1960’s, when this second speaker was installed in his main home to create a single “stereo”, the owner had an overcoat stain applied to the D-1005 to match the original D-1004 Dark Mahogany. I would have left it “as is”, however the topcoat looks poor. While it may have been a perfect solution at the time, the overcoat stain has not weathered the last 45 years very well, and further coats and finishes only made things worse. While the wood underneath the stain is in great shape, the stain has peeled and blistered over the decades. I am having this second speaker professionally refinished to remove the layers of topcoats and finishes applied to it over the last 60 years and stained to match the original dark mahogany D-1004. I am also taking this opportunity to remove and evaluate all of the drivers and crossovers, and have the cabinets and grills thoroughly cleaned. I expect this process to be finished in the next three weeks.

In preparing these two speaker systems for sale I have removed all of the internal components out to inspect, evaluate and meter them, and to have the crossovers restored with new premium capacitors to match the original specifications. In the photos you can see the size of these immense speakers - Behind them next to my fireplace are Thiel 3.6 speakers which are dwarfed by these majestic JBL D-1004 speakers. In the Photos, the speaker on the right is the first 1948 era D-1004 loudspeaker cabinet with the original Dark Mahogany stain, and as you can see it is in absolutely superb condition. The speaker on the left is the later cabinet, probably 3-4 years newer, and it was originally the “Vera Blond / Bleached Mahogany” color option (cabinet style D-1005), and has been artistically rendered to match the one on the right - the goal of this restoration project.

Here is a list of all of the internal components:

• D-1004 Speaker Cabinet / 16 Ohms / SN: 1615
• D-130 B 15” Woofer / 32 Ohm / SN: 11269
• D-130 B 15” Woofer / 32 Ohm / SN:

SPECIFICATIONS:

• Size:
• Weight:
• Manufacture Dates: manufactured from 1948-1953 (succeeded by the 1954 Hartsfield)

(Note – I will complete this list very soon and update the posting)

When these D-1004 speakers were built, JBL / James B. Lansing / Jim Lansing was in the absolute infancy of the company, and not very many of these very large speakers were ever built. To my knowledge not a single one has ever sold on Audiogon, and they have no listing on the Audiogon Price List. Few were ever made, and so very few of these giant speakers have even survived the past 60 years intact, unmodified, and not stripped apart. In the past seven years I have only seen two for sale online, and they were both just single D-1004 speakers, and one of those was pulled from its auction, stripped apart and the individual component parts sold separately in different auctions. Sadly, that is what has happened to virtually all of these remaining magnificent D-1004 speakers. In an interest to make a quick sale, most online sellers gut the cabinets and “harvest” the internal parts because they are so valuable and they are able to sell them quickly and ship them easily. These early “Jim Lansing” 130-B woofers are 32 ohm – not the usual 16 or 8 Ohm variant. Just the internal "parts” (woofers, horns, crossover, etc.) in this pristine condition are worth at least $3,200 on the used market, probably more. Sadly, most of the empty and gutted D-1004 speaker cabinets have just been junked over the past 6 decades.


Precisely dating these two speakers has also been a bit difficult, as I originally only had the owner’s surviving children’s anecdotal memory to go by to establish their history and purchase dates. I have copies of the catalogs dating from 1948 confirming the model origin and specifying the exact internal components. 60 years is a long time, in particular if you were just a child in 1948, but to the best of everyone in the family’s recollection the history is as follows:

• When Dad built the house (1948)
• When the first speaker was purchased (sometime around 1948-1949)
• When the second speaker was purchased (about 3-4 years later 1950-1953)
• Were they bought complete, built as a kit or copied from plans (they were both bought as complete finished speakers)
• Were they bought new or used (bought new)
• When were they were made into a stereo set (around 1964)

Unfortunately no original receipts or manuals survived the 60 year time period. On the internal drivers and crossovers I have the early paint colors to reference, and the early “Jim Lansing” logo decals, as well as the hand typed “cut corner” type model and serial number labels to go by to confirm their authenticity as well as the time period. However, at the time JBL was a tiny company and not quite settled into the manufacturing process, so the date codes used on their later models were not yet implemented. I have gone onto several forums to more specifically nail down anecdotal accounts from people who worked there at the time as well as people who collect these vintage JBL labels and can help pin point the exact model year.

Hopefully there are other people who love vintage JBL speakers as much as I and can help me pinpoint the exact manufacture date of these speakers. The N1200 crossover installed in the D-1004 (shown) is of the earliest variant in the first cabinet, while the N1200 in the later cabinet has the later three-way L-pad version.

If my goal was for a quick sale I would do what virtually everyone else has done with these majestic speakers – strip them down and harvest the parts, and sell them online. But I know that in my heart I just couldn't bear to do that - it's a crime, and I would carry that guilt the rest of my life. I am very passionate about music, audio systems and the industry as a whole, and preserving these iconic speakers is not just the right thing to do, but it is also a thrill!

My goal is to preserve these speakers at all costs. I realize that to sell them as complete speakers, and more important as a closely matched pair of speakers, may not just take months, it may take much, much longer. That is fine with me. My goal is to refinish these to their original glory, and to make them into a stunning matched pair for someone who will appreciate not just how fantastic they sound, but also how important they are from a historical perspective. One note is that the two grills are very close, but are not a perfect match. It is the same acoustically transparent weave, and same design pattern, but a slightly different combination of thread colors. They are close enough that when they have a few feet of separation they look identical, but when they are inches apart you can pinpoint the slight thread color differences. These grills have been removed and carefully cleaned to restore their original beauty.

Assigning a current used value to these speakers has been very difficult, as there really is no precedent. There is no question that this is probably the only remaining closely matched pair in existence, and from my research over the past seven years these are the only D-1004’s ever to be sold as a pair. So how much is this pair worth as the First JBL Statement Speaker by the greatest innovator in audio history? How much is a Rookie Season Babe Ruth baseball card worth - one of these sold in 2005 for $214,000. How much is the first year model Corvette worth - $300,000 – $500,000 buys you one of these, over $1,000,000 for one of the first 10 produced. How much is the first issue of Superman worth - this issue of Action #1 sold for just 10 cents in 1938, but today a good copy will bring $350,000 or more. Compare this set of seminal D-1004 speakers with its successor, the Hartsfield. Authentic Hartsfield’s in superb condition frequently sell for between $15,000 and $35,000, and one sold in 2006 for the astronomical price of $68,500!

I am asking $14,500 for this unique opportunity to own an authentic pair of James B. Lansing’s first flagship speakers. Not just a single speaker – as they were sold in that Mono era – but a very closely matched stereo pair. Authentic cabinets, authentic components, and authentic labels – even the original grills. All crossovers re-built to specification using premium audiophile materials, re-wired with audiophile cables, and all drivers checked and evaluated to be performing like new. And these are not just historically important and valuable pieces to be locked away unheard in some sealed chamber! Unlike the first Corvette that is sealed in plastic and up on blocks, or your babe Ruth baseball card or first Superman that is sealed in glass and no one can even breath on much less touch - these majestic D-1004 speakers are fabulous sonically and you can enjoy them all day, every day – properly cared for they will probably outlive all of us!

This is a pickup item only, and as such payment is via cash. Needless to say, these speakers are truly massive and require special accommodations for their safe shipment, or for pick up if you are going to audition them first. My goal is a local sale in the San Francisco area. NOTE - I am allowed to say that because this is a pick up only item, I accept payment upon pickup.. I can also deliver these for free after the sale if you are local to the San Francisco Bay Area, or for a nominal fee in outlying neighborhoods.

NOTE:

The two James B. Lansing D-1004 loudspeakers depicted in these photos are the actual two speakers for sale. One of the two speakers has been artistically altered to depict the result of a cabinet restoration that is not yet complete."

 

- Trích dẫn ý kiến của Bác Purser
"Em đang nhắm tới 4338 bác ạ. L200,L300 hay đến cả 4344 tiếng vẫn hơi khô,chưa có độ mướt & chi tiết của loa đời mới.[/quote]
"Mướt" với em là treble chi tiết hơn,âm thanh tổng thể mềm mại & không bị khô,đặc biệt khi nghe SACD bác ạ"

- Nghe vậy chắc Bác Purser đã chơi L200,L300 và 4344 bác mới quả quyết "tiếng hơi khô,chưa có độ mướt & chi tiết của loa đời mới". đã có lần tôi khẳng định JBL ko mạnh ở độ mướt & chi tiết, có thể bác Purser ở HN bác qua Thanh Tùng-Audio ở đó có vài hãng loa, bác nghe thử, bác sẽ có cơ hôi để khẳng định lại về âm chất của JBL. tôi dám khẳng định cái hơn của loa mới so với các loa cô, về độ động không gian điều này loa cô kém hơn, còn tạo âm hình và chiều sâu của âm hình thì như nhau, nhưng muốn có ko gian và âm hình hay còn phụ thuộc vào phòng nghe và setup phòng. Các dòng loa cô ko hề khô nếu bị khô là do thân chủ của nó khai thác ko đúng. cũng như 4428 khi khai thác ko đúng âm chất bị thưa, tính liên kết của 3 dải ko cao, nghe mỏng, r­ời rạc thiếu truyền cảm, điều này xảy ra khi ghép với các amply bán dẫn rẻ tiền. Tai nghe khác nhau vì vậy đánh giá khác nhau cũng ko có gì lạ. Có thành viên khác thác JBL rất môc mạc, âm chất chính xác. Có thành viên khai thác JBL có tính chi tiết cao, giàu nhạc tính. chính vì vậy chúng ta ko nên khẳng định hơn, thua, hay cái này hay cái kia kém. Tôi có cả 43.. và 44.... bác nào thấy điều gì tôi nói ko đúng, xin các bác góp ý giúp

 

Kính bác,bác nghe DD66000 treble Be mà bác bảo là không chi tiết thì em cũng chịu,hay tại tai em nó nhiều chi tiết quá?!
Em đảm bảo với bác 4428,4338,4348 cực kỳ chi tiết,còn JBL cổ(4344 MkII trở về trước) có nhược điểm mà người chơi khá đau đầu mà vẫn không thể giải quyết triệt để.
Trên cùng một bộ dàn đủ tốt,nguồn phát SACD,lần lượt chơi JBL monitor đời mới & đời cũ,các bác sẽ biết được mình được gì & mất gì. Nói JBL không mạnh về độ mướt & chi tiết,chỉ có thể là loa đời cổ.
Vài lời mạo muội.

 

Có gì mà ghê gớm đâu, quê em người ta dùng Mcintosh và JBL làm hệ thống phóng thanh chơi thôi các bác :lol: :
