E-Sub e112

Subwoofer activo de 12 pulgadas, 1500 vatios

Aplicando una serie de nuestras tecnologías clave, los subwoofers con alimentación E-Sub ofrecen una calidad de sonido, potencia y valor excepcionales en una amplia gama de aplicaciones exigentes

Los controladores E-Sub emplean nuestra tecnología DMA exclusiva para optimizar la fuerza del motor de los controladores, asegurando un comportamiento lineal en un rango de excursión muy largo. A diferencia de los sistemas típicos de modelado en estado estacionario, DMA tiene en cuenta los cambios dinámicos creados por el flujo de corriente y el EMF de retorno en condiciones de potencia real, con material de programa real. La recompensa que ofrece la optimización DMA es un controlador que rastrea fielmente su señal de entrada, en todos los niveles de audición, lo que lleva a una definición y dinámica de graves superiores.

La profundidad de montaje extrema del controlador E-Sub es muy deliberada. Permite la existencia de amplios espacios entre los tres elementos de suspensión (el borde de goma y las arañas duales), lo que imparte una estabilidad mecánica excepcional en todo el rango de excursión del conductor. Esto mejora aún más la linealidad, reduce la distorsión y mejora la fiabilidad a largo plazo. En un toque de elegancia de ingeniería, la brida de montaje frontal de acero del E-Sub forma el deflector frontal completo del producto terminado, mientras que la placa posterior del conductor está roscada y atornillada a la pared posterior de su gabinete para soporte.

Para alimentar estos controladores innovadores, diseñamos un amplificador de conmutación completamente nuevo con una fuente de alimentación de conmutación regulada, haciendo que su chasis sea más compacto, liviano y eficiente, a la vez que brinda una potencia amplia y limpia para ejercer completamente el rendimiento del controlador E-Sub.

Convenientemente controlado desde el panel superior del gabinete E-Sub, el amplificador incorpora procesamiento de señal de nivel de estudio para hacer que los ajustes sean una experiencia mucho más agradable que los controles montados en la parte posterior que se encuentran en la mayoría de los subwoofers con alimentación. Una cubierta atractiva oculta y protege los controles durante el uso normal.

El conjunto de características ha sido diseñado para permitir el uso de E-Subs en una amplia gama de aplicaciones, desde sistemas de cine en casa completos hasta sistemas de música dedicados de dos canales, hasta estaciones de trabajo de audio de escritorio. Se proporcionan entradas analógicas para señales de nivel de línea no balanceadas o señales de nivel de altavoz. Se incluyen salidas de línea dedicadas para hacer una disposición de sistema biamplificado sin necesidad de hardware adicional. Útil para combatir problemas de ruido relacionados con la tierra, un interruptor del panel posterior configura las entradas de nivel de línea como puestas a tierra o aisladas.

El crossover activo del E-Sub es un verdadero diseño Linkwitz-Riley bidireccional de cuarto orden, con un filtro de paso bajo que alimenta el amplificador del subwoofer y una señal filtrada de paso alto que sale de sus salidas de línea. Cuando se derrota el crossover a bordo, como es típico en una instalación de cine en casa, las salidas de línea entregan una señal de paso, idéntica a sus entradas de línea, permitiendo que múltiples E-Subs se interconecten en una 'cadena de margarita' ' arreglo. La polaridad conmutable y un control de fase completamente variable completan la sección de procesamiento de señal. Todo el procesamiento de la señal se realiza en el dominio analógico, lo que garantiza una latencia muy baja en aplicaciones críticas.

Construido con precisión en la fábrica estadounidense de JL Audio, todos los E-Sub se verifican y prueban individualmente para brindarle años de disfrute auditivo en su sistema de audio o cine en casa.

E-Sub e112-GLOSS

Powered Subwoofer with 12-inch Subwoofer Driver, 1500 watts


Applying a series of our key technologies, E-Sub powered subwoofers deliver exceptional sound quality, power and value in a wide range of demanding applications

E-Sub drivers employ our exclusive DMA technology to optimize the drivers' motor strength, ensuring linear behavior over a very long excursion range. Unlike typical steady-state modeling systems, DMA takes into account the dynamic shifts created by current flow and back EMF under real power conditions, with real program material. The payoff offered by DMA optimization is a driver that faithfully tracks its input signal, at all listening levels, leading to superior bass definition and dynamics.

The extreme mounting depth of the E-Sub driver is very deliberate. It permits wide gaps to exist between the three suspension elements (the rubber surround and the dual spiders), imparting exceptional mechanical stability over the driver's full excursion range. This further improves linearity, reduces distortion and enhances long-term reliability. In a stroke of engineering elegance, the E-Sub’s steel front mounting flange forms the entire front baffle of the finished product, while the driver’s back-plate is threaded and bolted to the rear wall of its enclosure for support.

To power these innovative drivers, we engineered a completely new switching amplifier with a regulated, switching power supply, making its chassis more compact, lightweight and efficient, while still delivering ample, clean power to fully exercise the E-Sub driver's performance envelope.

Conveniently controlled from the E-Sub cabinet’s top panel, the amplifier incorporates studio-grade signal processing to make adjustments a much more enjoyable experience than rear–mounted controls found on most powered subwoofers. An attractive cover hides and protects the controls during normal use.

The feature set has been designed to allow the use of E-Subs in a wide range of applications, from full home theater systems to dedicated two-channel music systems, to desktop audio workstations. Analog inputs are provided for unbalanced line-level signals or speaker level signals. Dedicated line outputs are included to make a bi-amped system arrangement with no additional hardware required. Useful in combating ground-related noise problems, a rear panel switch configures the line level inputs as grounded or isolated. 

The E-Sub’s active crossover is a true two-way, 4th order Linkwitz-Riley design, with a low-pass filter feeding the subwoofer's amplifier and a high-pass filtered signal exiting its line outputs. When the on-board crossover is defeated, as is typical in a home theater installation, the line outputs deliver a pass-through, buffered signal identical to its line inputs, easily permitting multiple E-Subs to be interconnected in a ‘daisy-chain' arrangement. Switchable polarity and a fully variable phase control round out the signal processing section. All signal processing is performed in the analog domain, ensuring very low latency in critical applications.

Precision-built in JL Audio's U.S. factory, all E-Sub are individually performance-verified and tested to deliver years of listening enjoyment in your home audio or home theater system.

DMA Optimized

Dynamic Motor Analysis - DMA Optimized Motor

Summary:
JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.

Detailed Information:
Since 1997, JL Audio has been at the forefront of Finite Element Analysis-based modeling of loudspeaker motors and suspensions. This research is aimed at decoding what we refer to as the "Loudspeaker Genome"... a project aimed at understanding the true behavior of loudspeakers under power and in motion. A major component of this integrated system is DMA (Dynamic Motor Analysis). Starting with the 15W3 and the W7 Subwoofers in the late 1990's and early 2000's, DMA has played an important role in the design of all JL Audio woofers sold today, including our component woofers.

DMA is a Finite Element Analysis (FEA)-based system, meaning that it takes a large, complex problem, breaks it down into small solution elements for analysis and then assembles the data to form an accurate, "big-picture" solution. DMA's breakthrough is that it actually considers the effects of power through the coil as well as coil/cone position within the framework of a time-domain analysis. This gives us a highly accurate model of a speaker's actual behavior under real power, something that the traditional Thiele-Small models or other low power measurements cannot do. Because DMA does not rely on a steady-state model, it is able to consider shifts in the circuit elements being analyzed. These modeling routines are intense, requiring hours to run for a whole speaker.

DMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the "fixed" magnetic field. This delivers intensely valuable information compared to traditional modeling, which assumes that the "fixed" field produced in the air gap by the magnet and the motor plates is unchanging. DMA not only shows that this "fixed" field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability. Analyzing this behavior is critical to understanding the distortion mechanisms of a speaker motor and sheds light on the aspects of motor design that determine truly linear behavior:

  1. Linear motor force over the speaker's operational excursion range
  2. Consistent motor force with both positive and negative current through the coil
  3. Consistent motor force at varying applied power levels
     

Our ability to fully analyze these aspects of motor behavior allows our transducer engineers to make critical adjustments to motor designs that result in extremely linear, highly stable dynamic loudspeaker motor systems.

The payoff is reduced distortion, improved transient performance and stellar sound quality.

True 2-Way Crossover

True 2-Way Crossover

Summary:
Built-in two-way crossover permits easy integration into two channel audio systems.

Detailed Information:
In high-performance audio systems, a crossover's function is to act as a gateway, filtering and directing precise audio signals towards each speaker as appropriate for its driver's particular size. For example, with a conventional two-way home theater or home audio system, the smaller, main stereo speakers are tasked with reproducing the mid to upper frequency ranges, while larger subwoofers are responsible for the lower frequencies. 

Designed with system versatility and practicality in mind, the E-Sub's onboard active crossover can be used in two distinct modes.

• When engaged, it send a 24 dB/octave, low-pass signal to the E-Sub's internal amplifier, while also feeding an alternate 24 dB/octave, high-pass signal to the "Line Outputs" located on the E-Sub's rear connection panel. The result is a true, two-way, 24 dB/octave, Linkwitz-Riley crossover configuration between the E-Sub and the main stereo speakers, without requiring an additional, external crossover.

• When the E-Sub's crossover is not in use, its "Line Outputs" will deliver a buffered, pass-0through signal that is identical to the signal feeding its "Line Inputs". This application is beneficial in multi subwoofer installations to pass a receiver/pre-pro's subwoofer signal from one E-Sub to additional E-Subs.

 

 

 

 

Vented Reinforcement Collar

Vented Reinforcement Collar (U.S. Patent #5,734,734)

Summary:
JL Audio's patented Vented Reinforcement Collar (VRC®) improves the rigidity and stability of the cone/spider/voice coil junction and directs airflow over the voice coil windings for improved thermal performance.

Detailed Information:
The Vented Reinforcement Collar (VRC®) is a composite structure that addresses two issues related to reliability.

By reinforcing the critical junction between the cone, voice coil and spider, the VRC greatly reduces failures due to glue breakdown or material weakness. It does this by greatly increasing adhesive contact area and providing stress relief to the spider material at excursion extremes.

Subwoofer VRC

The VRC™ also features slots that facilitate air flow directly onto the voice coil windings. This reduces thermal compression effects and enhances reliability.

Current versions of the VRC™ also incorporate lead-wire strain relief structures to improve mechanical reliability.

FCAM

Floating Cone Attach Method - FCAM™ (U.S. Patent #6,501,844)

Summary:
This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.

Detailed Information:
JL Audio's patented FCAM™ technology is an innovative method of bonding the surround/cone assembly to the voice coil former/spider assembly. This feature helps ensure concentricity of the surround, spider and voice coil without torquing the suspension to achieve it. This allows for the inevitable, slight variations in production part dimensions without having them negatively impact the integrity of the suspension and coil-centering at high excursions.

Engineered Lead-Wire System

Engineered Lead-Wire System (U.S. Patent #7,356,157) 

Summary:
Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.

Detailed Information:
Managing the lead-wires on a long-excursion woofer is one of the trickier aspects of its mechanical design. To address this, many long-excursion woofers today rely on a simple solution that weaves the lead-wires into the spider (rear suspension) of the driver.

The biggest problem with this approach is that spider limiting behavior plays a hugely important role a woofer's performance. Lead-wires that are attached or woven into the spider material can alter the spider's "stretching" behavior. The tinsel wire naturally has less 'give' than the fabric material of the spider leading to asymmetrical spider behavior and non-uniform stress distribution around the spider circumference. The wire attachment points can also cause localized pulling and tearing forces at the spider's excursion limits. As such, longevity becomes a major concern and makes the woven-in design less than ideal for very long-excursion designs.

While a traditional 'flying lead' design does not compromise spider linearity or radial stability, it creates its own challenges on a long-excursion woofer. Managing the 'whipping' behavior of the wire and making sure it does not contact the cone or spider is one challenge. Another is ensuring that the leads do not short one another or the frame of the woofer.

To overcome these issues, JL Audio's engineered flying lead-wires work in conjunction with carefully engineered entry and exit support structures molded into the terminals and the voice coil collar. Some models also feature jacketed lead-wires to further reduce the likelihood of shorting and fatigue. The result is flawless high-excursion lead-wire behavior, with outstanding reliability and none of the compromises inherent to a woven-in lead wire system. Building woofers this way requires much more labor and parts complexity than the simpler woven-in approach, but the payoff is in reduced distortion, reduced mechanical noise and improved reliability.
