DESCRIPCIÓN
El lanzamiento de la SUB DALI E-12 F marca una nueva etapa de lo que es posible en este nivel de subwoofers.
El subwoofer de DALI cuenta con un woofer de 12 ", capaz de mover un montón de aire con potencia y precisión. El cono está hecho de aluminio puro para máxima rigidez. Además, el sistema de imán pesado ejerce una enorme presión con sus 4-capas y carrera larga de bobina. Con todo, las capacidades de servicio potente de este "motor" aseguran que el woofer siempre mantengan la señal que emita el amplificador!
El corazón de este subwoofer de 170W RMS es el amplificador de clase D con una respuesta muy lineal. Emblema como clásico dentro de DALI es el objetivo de actuar como una extensión total de las frecuencias más bajas en de su sistema AV. El resultado es un potente y bien equilibrado nivel de reproducción de graves y la integración perfecta con los altavoces. Además, el limitador integrado ayuda a proteger su subwoofer contra sobrecarga.
La placa posterior de SUB 12 E-F controles de características para el ajuste del volumen, fase y frecuencia de corte superior, mientras que el encendido / apagado automático funciona de forma automática mediante la detección de la señal. Y con las opciones de LFE o entradas LINE, este subwoofer fácilmente acompaña a cualquier conjunto de AV.
E-12 SUB F se eleva desde el suelo gracias a una base de aluminio, mientras que un puerto de graves orientado hacia abajo permite colocarlo directamente en la pared. La parrilla delantera se monta por medio de imanes - y cuando se retiran, los cambios en la apariencia visual de discreto extravagante como el cono de aluminio puro se revelan sorprendentes!
El DALI SUB-12 F se recomienda como complemento a la serie Zensor nuevo y es compatible con todos los altavoces DALI como el complemento ideal para un conjunto DALI.
AMPLIFICADOR
The integrated 170 Watt RMS Class D amplifier is a highly linear construction. The DALI SUB E-12 F will follow and render the required signal with an absolute minimum of bias. Designed not only for continuous power, but also for peak power, this subwoofer is able to deliver 220 Watt Peak Power. This is very relevant when it comes to both movie and music signals.
Switchmode power supply is part of the reason for very low power consumption - only 0.4 Watt in stand-by mode. And the amplifier displays an impressive efficiency of 70%. In unison the high efficiency amplifier section and power supply construction generate an absolute minimum of heat loss. For that reason you will find no external heat sink on this subwoofer.
To improve sound reproduction in general, and to ensure that this subwoofer is able to perform under difficult circumstances, a limiter has been incorporated in the amplifier section.
The integrated limiter works in two areas: It compares the input signal amplitude to the potential output signal level, and it compares the available supply voltage from the power supply to the expected output signal. If any of these comparisons show that there will be a problem then the limiter will cut the signal in a soft manner and without affecting peak power.
Fitted with controls for gain, cut-off frequency, and phase, the DALI SUB E-12 F will adapt to any front speaker and room acoustics. And with a choice of LFE and LINE inputs it can be connected to almost any amplifier, receiver or processor.
HOME SYSTEM
Available in Black Ash, Light Walnut, and soon in White finish, the SUB E-12 F is the natural companion for many DALI speakers. It will complement any ZENSOR, LEKTOR and IKON MK2 system. Even customers for the FAZON F5 looking for more power than you can get from the FAZON subwoofers today will find what they need in this subwoofer.
And importantly; the design, technology, and construction of this subwoofer makes it a perfect upgrade of a speaker system of another brand. Whether it’s a 2.1-, 5.1- or 7.2-channel system – or something in between – the DALI SUB E-12 F will take natural sound one step further.
WOOFER
The DALI SUB E-12 F incorporates a large woofer with aluminium cone. This stiff, yet lightweight, material was chosen to ensure a greater transient response as you would normally expect from a subwoofer in this category. Very much in line with DALI’s philosophy in building speakers, the ability to start and stop very quickly enables easy integration with the front speakers. This goes for smaller front speakers as well.
Designed to be a closed cone you will find no dust cap. Instead it is an integrated part of the cone itself. This is also a contributing factor in ensuring a piston-like behaviour. Consequently distortion is kept to an absolute minimum – especially in the low frequency area which is where the subwoofer operates.
The engine of the woofer is built around an ‘oversized’ ferrite magnet, and optimized for maximum flux within the voice coil gap. The reason is that it was crucial for the project team to reach a high B/L product to enable the SUB E-12 F to render the finer low frequency details of music, also at a higher sound pressure level. The measured B/L value of 14 N/Ampere is a good indication of the level of control and precision that was reached, and rarely to be found in this category at all. And the numerous listening sessions has truly convinced us that this was the right way to go.
Adhering to the low-loss sound design principle, the surround of the woofer is built to allow long and linear excursion. The oversized suspension is designed to allow both weak and strong transients to turn into undistorted acoustic signals.
CARCASA
Built on almost 30 years of knowledge in acoustics and cabinets, the solid MDF cabinet abides the tough DALI specifications. The enclosure comes in a choice of Black Ash and White laminate finishes - with an updated front baffle in mat satin finish.
Any risk of port noise derived from the down-firing bass vent itself is seriously reduced by its convex tapered design. Apart from the shape of the flares the vent has also undergone extensive testing, measuring and listening when it comes to dimensions and placement, in order to optimize interaction with the cabinet and woofer.
The entire cabinet is effectively decoupled from the floor by means of a sleek aluminium base. Almost appearing to hover above the floor the distance of 30 mm eliminates any potential turbulence from the space between the cabinet and the floor itself. Still, the proximity to the floor ensures that the benefit of having a down-firing vent is maintained; a higher efficiency and more freedom in positioning - e.g. directly against the wall.
The front grille is mounted by magnets only – and when removed, the visual appearance changes from discreet to extravagant as the pure aluminium cone is revealed.
