JBL 4312A
JBL remains master in this MATIRE! JBL is info that invented the monitor here more than 40 years.
JBL is an assembler like many but a real manufacturer which manufactures all its equipments.
The 4312 is a concentrated technology that dates back to the 70's. This speaker does not even itch it, listen to a Gibson guitar on a Marshall, sings with overwhelming dynamics, rapidity of execution of the notes is impressive on a FENDER AMPEG has hit hard and fast, and the Hammond organ, its transitional mdiums so difficult to reproduce you transcend the Leslie is in front of you! These speakers are justices of the peace, a linearity unusual, they really let anything pass, gender breath of the singer before his Shure SM58!
They must be fed with a good amplifier mos fet transistors 2 x 200w kind QSC AUDIO, Mc INTOSH, CROWN, or LUXMAN + pramplificateurs tubes. 43 This series has been around the world, 70% of Supertramp Hallyday discs through BB King and Eric Clapton have another t enregistrs with this monitor.
Audiophiles is the individual are appropriate for their shows!
In 2000 the demand for many audiophiles JBL refabriqu this enclosure under the reference number 4312MK2 Black finish or wood.
PRESTIGE AUDIO VIDEO has devoted her a prestigious reporting.

Frquence the curve is more than perfect. This speaker is from the highly professional technology more draconian than Hi Fi.
The image is stro stupfiante;
the sound is a rare realism, the instruments are all WELL in place, the concert begins.
the dynamics is such a concert facade, it is in production, not reproduction is pro!


I use this place for over 25 years but youthful indiscretion, I sold my 4312.
when I saw that COBRA possdait a large contingent, I very quickly reserv. I got the desti- nations most recently because it was a studio Street and mlomanes audiophiles and connoisseurs !!
What I like most is the dynamic
least, nothing!
great price quality ratio (13000f pair)
Without a doubt, if I find new and February 1 very own pair, the purchase is insured! (To speculate)

JBL 4312A
For the size they do, I do not see the speaker equivalent (If the 4311 but more difficult and adnicher Magnat Ribbon with ... but I prefried my 4312 ..). I use it with different amps: Rotel, Harman, Proton, Hafler .. marier.je speaker rather easy to use it for listening to proximity .. (but even when nickel is far .. hi, hi,. ).. (This notice is for passive 4312a monitor speakers ..)


Medium and adjustments excellent, very precise and sharp


No regrets, I hope to keep them very very long time they have already more than 10 years and no date has ppins

JBL 4312A
I bought a pair of JBL 4312a 4 months ago for 650 euros (which is the average cte, now) they are MODELS 1991 (very important! The tweeter MODEL used varies depending on the year of manufacture and high cutoff frquence also consquent!) trs trs in good state for their age. JBL is tough!

These are passive speakers Troyes channels, impdance 8 ohms, sensitivity 96 dB, 1W @ 1M, the finish is "flat black".

I use in studio monitoring (ProTools) with an NAD 3220 PE in amplification. I also branch config 5.1 and Dolby surround another time on a big Onkyo audio / video.

As with any passive speaker, marriage with the amp is quite dlicat although the color remains substantially the same gnrale an amp on the other (I also have an old dual mono SETTON alternating with the NAD). In all cases it is necessary even when a lot of power for both driver that HP 30cm psent them all prs only 60% of the total weight of the enclosure (whew!)


In addition to quality indniables Aesthetics (they have the same head that the speakers found in the rooms of upscale fifth trs .... what!) These speakers poss rponse a tooth in a relatively tight frquence (35Hz 22 KHz) and fairly balance across the spectrum.

There actually a rsonnance to 5 kHz and mdiums of Manir gnrale are frankly forward. Default (or quality?) That can be corrected with the two knobs aisment correction (Mid and TREB) disposs in faade (It is interesting to note that when a the two knobs is 0, the HP corresponding time.

Stereo image is excellent, with a center fantme trsraliste spacialiss goods and treble (ah, the rverbs!) But be careful! should be well placed in the local costs because all medium / high rev is directional (the opening is 110)! I got personal best in the rsultats plaant far enough from the point of costs (2 to 3 meters around) which has an area of ​​consquence costs far more cohrente in the top end ..... and then as they are far little send level and is the fte.

The dynamics are impressive, the highs are trsars (hey, it's not as prcis DMES as titanium, but hey ...), down mdiums is tense and pr cis (kick hello!) especially a good listening level. Moreover it down enough at the bottom to allow good CONTRL bass to the mix or mastering for example.

Home cinma in config, the timbre of the voice is just trs, moods and dynamics ralistes offers beautiful sensations (you can even dye sub ...)


I use fawn intensive since 4 months and I think I fell in love ...

What I love is their precision and in prsence mdiums just in the minds of NS10 with HP papers (the lower and more!) And personality! Mention specially for HP JBL 30cm (the white!): This velvet! There that will make a phone "mlody nelson" (it is in the mouth gainsbourg), or a stroke of "Beat it" (the solo of Eddie Van Halen and Pearl litralement pregnant), or a good old AC / DC like "Back in Black" (Angus is the pice ...) to be convinced. What is funny is that the quality of the productions of 70/80 (on the good disks means ..) is rvlent carrment on these forums! with a good turntable is paradise ....

Moreover, we can not say that the 4312A are the speakers really transparent, but it's what makes them always a little quality in the minds of NS10. When the costs, we hear the speaker, the HPs, but it's what makes them charming, I think. But let's not forget that the basis is the monitoring even if poss some audiophiles have in their living room (the Japanese are crazy !!!).

In short, what the price (and if they are found, hhh ...) is a steal! ACCS and was the monitoring speakers (used in many pro studios for years) for the price of two Tannoy Reveal (the joke ...) I compare a pair of Genelec 1031 active (same studio, same listening level) and there's no photo ... The JBLs prevail at The definition, clarity and not to mention the vibrant color and fun to MUCH ....

So I would do without this choice problem especially in this price range, the thing is that we must place and have deaf neighbors.

ah! There's so one problem is the weight (22kg pice, ouch!) but hey, it's the same problem with a marshall amp body lamps 3, c ' is cumbersome and annoying but it carried with a record that has 80% of the 30 best albums produced dernires year!

short, you'll understand what the 4312 did not have the most part of home studio speakers of today: a me!

mattera91's review (This content has been automatically translated from French)

JBL 4312A
I for my part, the B version (no problem demagnetization to fear), used a quick e w 2 x 110 effective. The boomer is not passively filtered on these versions, hence the invigorating spontaneity .... Ideal for chronic depression! Personal, home use in a room of 9m2, at levels sometimes indecent for the environment ...


What can I say that everything has been said about them? Each Internet forumeur below, proud owner of these speakers, has, I believe, bring out their main quality is above all, to summarize, life and the generosity of the music ...

Even if I am lucky to have as real monsters among the most prestigious brand, I find in this volume, they combine the essential qualities (especially precision and vividness of the spectrum), those who are pleased to listening to modern music at home. The dynamic is quite the appointment, and powerful enough amps do not scare them.

Do not look for the low bass on this model, there is not, it's a deliberate choice of the manufacturer the benefit of the speed and performance, and it's not worse. Anyway, it will always be illusory to try to reproduce the core of an organ in this volume. All we get to win a few hertz, it is a slow and a lack of performance would not be acceptable to the basic qualities required.

So no frustration in this area, because the laws of physics are a must, knowing that everything is a matter of compromise, and what loses a little on this side, we find happiness with a bonus on the essential criteria.


What I like most? clarity and speed, they leave nothing in the shadows .. What I like least? compared to the most prestigious models of the brand, a character can be said too, but in any case less than the older versions that lacked finesse at the top.

I know almost the entire range hifi and pro brand, I am a real passionate bulimic.

The quality / price / pleasure seems unbeatable. This choice is recommended without reservation unless exclusive fans of classical music, who prefer a sound stage with more perspective, with some "sentimentality" (uncritically) to dream, completely absent on this model.
