Auf der High End in Muenchen im Jahre 2017 gab es viele gut klingende Systeme zu bestaunen, einen wirklich nachhaltigen Eindruck hat bei mir aber nur die JBL 4367 zum vergleichsweise günstigen Preis von 17.000,- eur / Paar gemacht. Da der Lautsprecher aber lange Zeit nur sehr schwierig in Deutschland zu hören, zu kaufen war, hatte ich die JBL 4367 recht schnell wieder vergessen gehabt. Erst durch meinen Kontakt mit den JBL 4312SE erinnerte ich mich wieder an die gute Vorstellung der JBL 4367 im Jahr 2017.
Auch erfuhr ich erst auf der diesjährigen High End ein paar Hintergründe. So zB dass einige der legendären JBL Lautsprecher der "damaligen" Zeit von einem damals jungen Ingenieur namens Chris Hagen geprägt worden sind.
Dieser hat seine Karriere bei Miller&Kreisel und später bei Velodyne fortgefuehrt. Erst die Harman Luxury Group hat ihn zurueck zu JBL geholt und verantwortlich fuer die aktuellen JBL Lautsprecher gemacht.
So entstammen unter anderem die aktuellen 4312se, die 4312G, die 4307, die 4367 , die L100 usw aus seiner Hand.
Speziell mit der grossen JBL 4367 hat er gezeigt, wozu er in der Lage ist, gefiel mir der LS doch spontan besser, als ich meine damaligen K2 9800 in Erinnerung hatte.
Auch aktuell ist es nicht ganz leicht, ein Paar JBL 4367 in Deutschland zu hören zu bekommen, so bin im im Moment sehr froh, dass mir das letzte im Moment frei verfügbare Paar dieser Lautsprecher für meinen JBL Workshop am 15.6. von Harman Deutschland zur Verfügung gestellt wurde. (Neu Paare sind auf dem Weg)
Bevor ich von meinen ersten Eindrücken erzähle, hier das white paper von Chris Hagen:
INTRODUCTION
JBL loudspeakers have been the choice of music and movie professionals for more than 60 years; they are behind the screens of more than 50 percent of all movie theaters and hang in concert venues everywhere. In fact, the line of JBL Studio Monitors dates to almost 50 years ago; yet the spirit behind their design began with James B. Lansing himself.
This spirit has always been to use the best technology to deliver the best performance. To the Studio Monitor legacy, this has resulted in increasingly louder speakers of steadily greater dynamic capability, increasing accuracy of reproduction, all with JBL’s unique “bullet- proof” approach to design and assembly.
The flagship JBL 4365 Studio Monitor was first produced in 2010, setting new levels of performance by employing the 1501FE-8 15" woofer, a 476Mg high-frequency compression driver and horn, and an 045Ti -1 ultra-high-frequency compression driver and horn.
Now, the award-winning 4365 has been eclipsed by the new JBL 4367 Studio Monitor. The 4367, a result of further refinement of the design, uses a new version of the 2216Nd woofer as well as the patented dual- diaphragm D2430K driver coupled to a new patented High-Definition Imaging (HDITM) waveguide horn. The
new 2216Nd-1 has been refined for a more articulate and defined low end, while the two high-frequency drivers of the 4365 have been replaced by the new, patented D2430K dual-diaphragm driver and HDITM waveguide horn for increased output capability and to match the low frequency power compression in the high frequencies. The D2430K also now lets the 4367 produce high- and ultra-high-frequencies from a single coincident source, improving the imaging capabilities of the system.
Although this may sound like the JBL 4367 is solely a professional monitor, but its accuracy, lack of power compression, and enhanced imaging make the 4367 a perfect choice for critical listening in 2-channel audio systems or for the LCR speaker system in a high- performance multi-channel home theater installation. Enhanced components used in the crossover for frequency division as well as for making connections help ensure audiophile levels of performance, while the attractive walnut and black walnut wood veneer enclosures allow the 4367 to blend in at home
SYSTEM OVERVIEW
In the 1950’s and 1960’s, JBL built mainly 2-way systems with a 12" or 15" woofer crossed over to a large-format compression driver/horn combination. The 4367 is a return to that tradition. Similar to those highly acclaimed speaker systems, the 4367 has a crossover at a single frequency, away from the most sensitive frequency band of human hearing.
Although this seems a very simple system, it is in fact simplicity at its best – the compact, symmetrical system with a single crossover is characterized by a compact acoustic focus point with exemplary control of its off-axis energy.

The acoustic components are housed in a traditional JBL Studio Monitor series-style of cabinet with a clean, professional design. The heaviest component of the design, the cabinet has 1" thick MDF walls and an additional 5/8" thick surface baffle below the horn for a total 1-5/8" thick massive and unmoving support for the woofer. Rigidity is further enhanced by the use of two varying braces connecting all of the vertical panels. The cabinet, with beveled front edges is available in a furniture-grade walnut finish wood veneer or black walnut wood veneer.
Although the 4367 is a two-way speaker, the innovative crossover provides front-mounted controls for both high-frequency and ultra-high-frequency ranges. Rear gold-plated connections are provided for bi-amplification or bi-wiring through the separate networks, but heavy-duty jumper wires are provided for single-amplifier usage as well. The natural roll-off of the woofer is extended by two 4" diameter, dual- flared ports, front-mounted for more impact.
The grille, designed to be very open and have minimal effect to the 4367’s acoustic response, is bowed for more rigidity, resulting in a very light and easily removed grille. The 4367 has four low-profile feet made of three solid pieces of black-chrome- plated brass: a glide, a point that threads into the glide, and a cup to protect fine flooring.
