• ELAC Concentro M 落地式揚聲器 規格表

Concentro M Floorstanding Speaker

Concentro M 喇叭箱體造型完全跳脫 ELAC 的傳統設計，箱體採用橢圓流線造型，前障板也採用橢圓造型，正面仍然只設置一支 ELAC 著名的 JET 5 同軸中高音單體，證明 JET 5 承載力及聲壓輸出相當之高 ，才能夠與四支低音一起發聲，在大音壓下保持全頻平衡。中低音單體採用三明治結構，加上 AS-XR 水晶表面振膜，所有單體皆採 LLD 長衝程高線性設計，並且加上了 VX-JET 可調式同軸高音設計，可根據現場環境調整 Spacious（空間感）與 Focused（聚焦）。低音單體則是使用了四支 10 吋低音單體擺在兩側，採用 Push-Push 與 Pull-Pull 設定，以呈現出準確而強悍的低頻。

Sophisticated aluminum woofers
Through the use of aluminum, resonances that affect the linearity of common paper cones can be placed beyond the driver’s operating frequency range. The motor structure features a large 3-inch diameter voice coil with oversized magnet and a vented pole piece to increase power handling, for accurate reproduction of bass frequencies that are clean, clear and powerful.

Crystal membrane midrange and mid-bass drivers
The eye-catching surface of the crystal membrane is more than just an attractive design feature. The midrange/woofers of the Concentro employs the Crystal Membrane (patent pending) and the 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.

JET 5 tweeter
Delivering true high-definition sound, ELAC’s JET 5 tweeter 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 neodymium magnet. This motor drives the air considerably faster than that 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 hi-res formats.

Custom base
The base of the Concentro is a complex design machined from a single piece of aluminum that has a matt, clear-anodized -finish. Weighing more than 55 lbs, the base employs four adjustable, high-definition spikes for maximum stability and ideal coupling to hard or soft floor surfaces.
