JBL releases VTX F, VTX V20 and Eon 615 speaker systems
As part of its 2014 line-up, JBL has introduced an array of new products including a comprehensive selection of speakers and a new line array system.
Adding to its VTX Series line arrays, the company has introduced the VTX V20 dual 10-inch line array loudspeaker and VTX S25 cardioid-arrayable dual 15-inch subwoofer. Both products are stated to offer the same ‘unmatched sonic clarity, high power density and precise coverage as their predecessors (the V25, S28 and G28)’.
According to the manufacturer, the VTX V20 loudspeaker features a 3-way system design with a proprietary D2 dual diaphragm dual voice coil compression driver and differential drive low frequency transducer technology along with its patent-pending ultra-linear motor technology for midrange components.
The V20 is stated to have ‘extremely high power density’ with each line array element featuring two 2261H 10-inch differential drive woofers, four 2164H 4-inch ultra-linear midrange transducers and three of the new small-format D2415K dual drivers. It also features three D2415K transducers – a new small format version of the patented D2 dual diaphragm, dual voice coil annular (ring radiator) compression driver that JBL says ‘delivers a dramatic increase in high frequency extension and sound pressure levels with significantly lower distortion, reduced power compression and lower weight combined with increased power handling, linearity and dynamic headroom’.
Features for the V20 include a Radiation Boundary Integrator (RBI) waveguide based on the same design principles that have been employed for both the VTX V25 and Vertec VT4886 subcompact line array elements. It provides a 110-degree horizontal coverage combined with line source array coupling from 0 – 12.5-degrees in the vertical plane. The V20 has a modular design with a cast-aluminium baffle and HF waveguide construction that reportedly allows the enclosure to achieve the same tightly-packed power density as the V25 along with the added benefits of light weight, improved structural rigidity and enhanced heat dissipation. The VTX V20 series features JBL’s ASM Suspension System.
Released as a companion to the V20, JBL’s VTX S25 subwoofer uses a pair of the same 2,000W continuous, 15-inch differential drive transducers employed in the full-size V25. The S25 is cardioid-arrayable, and can be suspended in the middle of V20 arrays to provide balcony/floor coverage and under-balcony penetration for theatrical sound design. Alternatively, S25 enclosures can be positioned at the top of V20 arrays in either front firing or cardioid mode to extend the low frequency length of the line array and provide improved low frequency pattern control and throw.
As an accompaniment to the VTX series line arrays, the company has introduced the VTX F-series, a premium line of 2-way multi-purpose loudspeakers. The F Series includes three models – the F12 and F15 full-range loudspeakers and the F18S subwoofer.
The VTX F12 and F15 loudspeakers feature the large-format JBL D2 dual diaphragm dual driver employed in the VTX V25 line array and the M2 master reference monitor. All F Series models also feature JBL’s differential drive transducer technology.
The F15 is a bi-amplified 2-way enclosure that features a progressive transition waveguide (90- x 50-degrees) and a 2265H 15-inch diameter (3-inch) dual voice coil, neodymium transducer.
The F12 and F15 are optimised for use with Crown I-Tech HD Amplifiers and Crown VRack amplifier management systems, and include NL4 connectors, 14 M10 mounting points and an optional universal bracket.
The VTX F18S is a subwoofer that is ‘ideal for drum/DJ monitoring and small/medium format front-of-house applications. It features the 2269H differential driver 18-inch transducer, with 2,000W continuous power handling and 8,000W peak. It is reverse-cardioid arrayable and has a reinforced M20 extension rod receptacle and 16 M10 mount points.
The Eon 600 series are the latest addition to JBL Professional’s Eon portable loudspeakers. Specifically, the Eon 600 series have been optimised to bring the benefits of high-end studio monitors to a flexible, easy-to-use PA system.
Described by the manufacturer as a ‘complete departure’ from traditional approaches to affordable, self-contained and portable PA systems, the Eon 600 series was specifically designed using JBL’s waveguide technology and proprietary transducers.
The Eon 615 is the first in the series – a 15-inch two-way loudspeaker featuring built-in 1,000W power amplification, providing ample headroom for a variety of applications.
Key to the Eon 615's appeal is its approach to waveguide design, claiming to solve the inherent ‘beaminess’ of conventional speaker systems that causes them to have a different frequency response off-axis than on-axis. JBL engineers examined the radiation characteristics of the Eon's high- and low-frequency drivers at 36 different points employing the manufacturer's measurement techniques, then designed individual waveguides for both components that control the sound radiation at the high frequencies, the crossover point, and at the low frequencies.
Special fluting has been installed into the structure that guides the frequencies through the full range of the system, reportedly resulting in consistent response throughout its 90-degree coverage pattern. The quality and consistency between on-axis and off-axis response delivers uniform coverage and high intelligibility.
Not stopping there, JBL engineers also recently developed an iOS and Android supported interface to be paired with the Bluetooth Smart Ready 4.0 for controlling master volume, adjusting the five-way, user-definable parametric EQ, and saving and recalling user presets.
The interface controls Eon’s onboard 32-bit, 130mHz audio DSP sub-system, while four strategically placed handles allow for easy handling.
