DESCRIPTION

Le caisson DALI SUB E-9 F est très compact (à peine 30 cm de côté) et peut s’intégrer dans n’importe quel système stéréo ou home cinéma composé de DALI ZENSOR ou FAZON par exemple.

Un haut parleur de 230 mm alimenté par un amplificateur digital très puissant de 220 Watts vous garantit des basses profondes, denses mais aussi précises et maîtrisées. La membrane du haut parlée est fabriquée en aluminium, ce qui apporte à la fois rigidité et légèreté et confère au caisson un look high tech du meilleur effet!

Le joint en caoutchouc largement dimensionné, le système magnétique généreux et la bobine massive 4 épaisseur permettent un grand débattement de la membrane et par conséquent, un important déplacement d’air, renforcé par le port bass reflex. Le SUB E-9F descend jusqu’à 37 Hertz et produit une pression acoustique de 111 dB.

L’amplification digitale très soignée apporte un plus immense au SUB E-9F :170 Watts en continu et 220 Watts en impulsion. Mais la puissance n’est rien si elle n’est pas maîtrisée. Naturellement, le SUB E-9F est équipé de tous les réglages traditionnels: volume, fréquence de coupure (40-120 Hertz) et d’un sélecteur permettant d’ajuster le rendu sonore à l’acoustique de votre pièce d’écoute. Vous pourrez connecter votre caisson DALI à la sortie LFE de votre amplificateur home cinéma ou à partir d’un signal stéréo.

Le caisson DALI SUB E-9 F est disponible en trois finitions: vinyle haute qualité frêne noir, noyer clair et en blanc. La façade est laquée noire ou blanc selon la finition choisie. Différentes grilles disponibles en option peuvent être fixées magnétiquement. Des pieds en caoutchouc assurent le couplage acoustique du caisson.

WOOFER

The DALI SUB E-9 F incorporates an aluminium cone woofer. 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.

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-9 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.

CABINET

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, Light Walnut and White laminate finishes. The front baffle itself displays a High Gloss Black finish.

The entire cabinet is effectively decoupled from the floor by means of four polymer based oversized spikes. 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.

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.
