4349
Designed and engineered in JBL’s world-famous acoustic engineering facility in Northridge, California, the 4349 Studio Monitor is a showcase of patented JBL acoustics technologies. This monitor loudspeaker features a 2-way design with patented High-Definition Imaging (HDI™) horn technology, the patented D2415K dual 1.5-inch (38mm) compression driver, and a 12-inch (300mm) cast-frame, Pure-pulp cone woofer for powerful dynamics and incredibly accurate sound reproduction.
JBL’s revolutionary High-Definition Imaging horn geometry is the result of intense research into the nuances of horn design. In search of exceptional high-frequency detail and uniform directivity for smooth in-room response, JBL engineers pioneered a design that delivers neutral frequency response both on- and off-axis and provides a seamless transition between the high and low frequency drivers.
The JBL D2415K compression driver benefits from the advanced research and applications derived from JBL Professional’s “D2” range of transducers. At the core of the D2415K device is a pair of lightweight, polymer, annular diaphragms that improve high-frequency extension by reducing diaphragm mass. The V-shaped geometry of the annular diaphragm reduces breakup modes, eliminating time smear and reducing distortion. The result is incredible dynamics with accurate reproduction and a lack of power compression. The “D” prefix indicates that this driver utilizes dual diaphragms, dual voice coils, and dual motors for an incredibly efficient design.
High-frequency and Ultra High-frequency tonal adjusters are located on the front panel below the horn and allow the sound to be tailored to the specific environment and listener preference. These controls work in conjunction with an advanced crossover network design that features air-core inductors, cast wire-wound resistors and low-ESR metallized film capacitors in a multi-cap configuration to optimize the performance of 4349 drive components. The multi-cap technique improves series capacitance by averaging their values while lowering ESR and distortion.
The 4349’s powerful 12-inch (300mm) woofer takes advantage of core JBL engineering techniques to ensure very high output with low distortion. The 3-inch (75mm) long-throw voice coil in conjunction with dual opposing spider dampers guarantee maximum output with significantly reduced distortion. A Pure-pulp cone provides a lightweight, rigid diaphragm and helps to eliminate breakup modes ensuring proper pistonic motion throughout the operating band.
The 4349 enclosure is heavily braced with 1-inch (25mm) thick walls to provide a solid acoustic foundation and incorporates a bass reflex design with dual front-firing, computer-optimized flared ports. The cabinet features a classic JBL studio monitor design with a blue baffle and is finished in a choice of Walnut or Black Walnut furniture-grade satin wood veneers. A blue (Walnut) or black (Black Walnut) cloth grille completes the elegant appearance. Dual sets of gold-plated binding posts provide a secure connection and offer a choice of single-ended or bi-wire/bi-amplified connections.

YG Acoustics, a world-leading ultra high-end speaker manufacturer located just outside of Denver, Colorado announces the departure of its founder, Yoav Geva. Mr. Geva launched YG Acoustics in 2002 at age 24. Through the course of 15 years of innovation and hard work he cemented YG Acoustics as mainstay in the global ultra high-end speaker market. In 2017 Mr. Geva sold YG Acoustics but remaind with the company in an engineering capacity. Under the leadership of CEO David Komatz, YG has expanded its worldwide reach and is now distributes to audiophiles and music lovers in nearly 50 countries. YG continues to be an innovation firm and a precision manufacturer. In addition to its eight unique key technologies, YG has a roadmap of innovations which will appear in future product releases. Among things to look for are a line-up of more accessible speakers as well as advances in YG’s statement model Sonja XV. We can only tease at this time, but stay tuned for a truly unique paradigm shifting offering on the horizon. All of us at YG Acoustics offer thanks and well wishes to Yoav.
Ansuz tried to make the best out of the Corona-lockdown. We invested that time to focus our endeavors on searching for ways to further develop and improve our product range. In line with the Ansuz mantra: solid grounding, low capacitance and low inductance, we found that we could remarkably elevate the performance of our D·TC series if we applied and integrated our most recent advancements in Ansuz technologies.
What followed was a series of extensive trials and elaborate audio testings that helped us identify and filter out the entire potential of acoustical improvements that would advance our new D·TC series to an unprecedented new level of musicality – so outstanding and unique – that we had to celebrate this with the launch of the brand new D·TC2 series.
You may already be familiar with our Ansuz products and have experienced the enormous musical potential that is inherent in all of them. But the new Ansuz D·TC2 series has now pushed open the musical gateway to the ultimate performance in musicality. The new D·TC2 series advances audio quality and its authenticity from better to simply the best.
Here are the key Ansuz technologies that have been integrated into this new D·TC2 series:
Active Tesla Coil
This is an active noise suppressing element that relies on the mains spike noise cancellation.
Active Square Tesla Coil
This active type of coils is embedded on both sides of the double-sided circuitry board.
Active Cable Tesla Coil
An active coil type that is acting directly on the mains wires.
Analog Dither
The analog dither reflects a vital part of Ansuz technology that we use in a wide range of our products. The dither is adding a very low-level random noise pattern and modulating the noise floor. With this pioneering technology, it is possible to hear what is below the noise-floor. Thus, it provides more transparency and a deeper penetration into the full potential of the musical source.
Anti-Arial & Resonance Coil
All cables and cable screens act like antennas. By fitting AARC in our cable structures, we reduce the cables’ ability to absorb airborne RF/EMI. The mechanism of the Ansuz AARC technology is to make sure that the cable has no definitive length. That way, the cable or internal wire cannot act as an antenna. Thus, no standing waves can be absorbed in the cable and infiltrate your audio system.
Double Anti-Arial & Resonance Coil
By integrating two sets of our AARC in our cable structures, we further reduce the cables’ ability to absorb airborne RF/EMI.
The new D·TC2 series is expected to be available to lovers of high-end music some time between July and August 2020 at our premium dealers.
