•BS 302 參考規格

Line 300

兩音路書架揚聲器的完美典範

本系列以鉛合金打造音箱，強度特佳，無衍生諧振造成之音染，彷彿沒有音箱，單體運動自由，保持聲音最高純淨度。

BS 312及BS 314最新JET5，主要進化低端延伸可達1.3kHz，配合全新分音器,，不但中低音單體工作更輕鬆，整體銜接也更平順，新的高剛性水晶鋁/紙複合三明治紙盆低音單體也經過進化，懸邊、彈波以及阻尼的方式都經過改良，達到更平坦的頻率響應，在高音壓下聲音依然保持穩定性、下潛低音、低失真、準確音色、高分析力、磅陀氣勢，以及自然音樂性。繼承310二十年來的優良傳統。

BS 302擁有全世界最小也最發燒之同軸單體。其低音呈橢圓形，新絲質軟半球高音單體頻率寬闊，配合20mm 口徑音圈與強力釹磁鐵，動態強橫。搭配超低音，彷佛大喇叭般。BS 302可搭配專用吊架，吊掛於牆上或天花板上，讓它適合2.1及環繞聲使用。

The sonic miracles.

Be amazed by the volume these compact loudspeakers can produce. Both models in the Line 300 deliver an extraordinary audio experience for their size, thanks in part to aluminum cabinets that are rigid, lightweight and allow for a narrow profile that minimizes the diffraction effects of larger cabinets.

Crystal membrane driver

The eye-catching surface of the crystal membrane is more than just an attractive design feature of the BS 312. The Crystal Membrane (patent pending) design is based on ELAC’s Aluminum-Sandwich AS Technology. The crystal-shaped inverse aluminum dome is joined to the paper cone in a special gluing process to result in the desired sandwich construction. Resembling the surface of a large crystal, the aluminum-foil stamping stiffens the aluminum dome, diminishing resonances and minimizing coloration, while improving power handling and dynamics. The voice coil design of the driver results in an expanded frequency range, and driver surround allows for longer cone excursions for truly prodigious volume and lowest distortion, a unique engineering achievement for a driver of its size.

JET 5 tweeter

Delivering true high-definition sound, ELAC’s JET 5 tweeter used in the BS 312 enthralls with its lightning-fast response and wide dynamic range, offering minimal distortion, lots of headroom and a distinctly wider frequency range than conventional dome tweeters. The ELAC JET tweeter is one of the most legendary tweeters in the industry and has won international praise with its transparent and effortless sound image.

The JET tweeter was developed to perfection on the basis of the famous Air Motion Transformer by loudspeaker pioneer Dr. Oskar Heil. Its operating principle is based on a concertinaed-foil membrane, driven by a strong magnet system of neodymium rods. This motor drives the air considerably faster than the pistonic motion of a conventional driver, with gains in higher sensitivity and extraordinary dynamics. Due to many additional design changes, like an improved new neodymium magnet system, even higher efficiency, higher sound pressure levels and frequency response up to 50 kHz was achieved.

The core of the JET tweeter is the folded foil membrane. With a fold width of only 0.84 mm, a major requirement in the JET production is precision. To guarantee repeated accuracy and unchanging quality even with high production capacity, gluing and handling are now executed by two SCARA robots. The folding and fixing of the membrane, however, are executed by hand, since for production steps requiring extreme precision, the manual dexterity of skilled technicians is irreplaceable. Due to continuous improvement, the JET 5 tweeter creates an effortless, airy and resonance-free image up to 50,000 Hz, and with its linear frequency response is ideally suited for the reproduction of DVD-A and SACD.

Bass reflex port

The bass port of the BS 312 is a proprietary design feature. Flared on both sides, the double-flare port has been designed to minimize ventilation noises and to reduce friction losses of traditional ported cabinets.

Bass control

The sound of loudspeakers is heavily influenced by room-acoustics. In some cases the room shape and especially the furnishings offer less than ideal conditions for the optimum set-up of the loudspeakers, sometimes resulting in bass reproduction that is too strong. Closing the bass reflex port of the BS 312 compensates for unfavorable acoustic conditions when speakers are installed, for example, close to a wall. When loudspeakers are used close to walls or in small rooms and the bass is too prominent, the ELAC Bass Control plug can be used to improve the bass reproduction by reducing the low frequency output. Just insert one or both of the supplied ELAC Bass Control plugs into the bass port until the bass is at the correct level relative to the midrange and treble.

Magnetic shielding

With the cinema-friendly BS 302, you can watch television without having distorted color. Thanks to magnetic shielding, this loudspeaker can be installed right next to CRT screens or devices with hard drives sensitive to magnets without creating interference.
