ELAC Concentro S 503 書架型喇叭、揚聲器
“Legendary technology presented in bombastic style – with this new flagship model, ELAC is laying down a clear marker for the years leading up to its centenary celebrations.”– Best Of High End Concentro S 503 全部搭載 Elac 最高階的特製單體，包括最新世代的 JET 5c，搭配 130 mm AS-XR 三明治結構鋁合金振膜單體，以及 180 mm AS-XR 振膜低音單體，所以，以技術面來說，Concentro S 503 除了喇叭箱體尺寸縮小了，其他都是正統 Concentro DNA 傳承。
Concentro S 503 還增加了 StepX-JET 的設計，這是控制中頻指向性的 DCR 配件，可以自己更換，依照空間聲學條件，搭配合適的 DCR 配件，讓 Concentro S 503 具備更高的空間適應能力，此外，Elac 同時推出搭配 Concentro S 503 的 LS 100 專用腳架，不僅視覺效果好看，而且可以鎖定喇叭箱體，擺放更為牢靠。
Concentro S 503 Bookshelf Speakers
No doubt: the S 503 is real in every respect Concentro. Design features and technical details that have justified the success of the S 507 and S 509 ported to compact dimensions. The trapezoidal basic shape and the inclination of the housing fit together remarkably organically and create a strong visual moment.
The long list of patented features and that revised woofer magnet system for outstanding acoustics. Absolutely confident in the Performance, scalable in the room acoustic effect: if you close your eyes, the thought of one is lost Compact speakers … you just listen to music.
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.
