Volker Schwerdtfeger, 德寶 quadral CEO.

……是我們的激情。難怪我們是德國最受尊敬的揚聲器品牌之一。40多年來，quadral 這個名字代表了漢諾威的高品質高保真音響組件。

除了不同價格類別的揚聲器，我們還為國際客戶開發(fā)和分銷獨家高端電子產品。

… is our passion. No wonder we are one of the most respected loudspeaker brands in Germany. For more than 40 years, the name quadral has stood for high-quality hi-fi components from Hanover.
Besides loudspeakers in different price categories we develop and distribute exclusive high-end electronics for an international clientele.

我們的理念

所有揚聲器都可以完全互換嗎？或者它們之間是否有細微差別？我們相信，在工程，設計以及尤其是聲音方面確實存在重大差異！但是，德寶 quadral 揚聲器與其他揚聲器有何區(qū)別？

OUR PHILOSOPHY

Are all loudspeakers fully interchangeable or are there fine differences between them? We believe there are indeed major differences with regard to engineering, design and, above all, the sound! But what distinguishes quadral loudspeakers from the others?

工程

德寶 quadral 揚聲器的設計方式使其可以搭配任何功放，這意味著您可以將它們與幾乎任何音樂系統(tǒng)結合使用。

產品開發(fā)的最前沿不僅是個人細節(jié)的完善，而且是與聲音相關的任何弱點的最小化（根據(jù)價格類別進行分級）。我們的目標不僅是使揚聲器與各種音樂系統(tǒng)協(xié)調一致，而且還要使各種音樂風格協(xié)調一致。這樣，材料的質量和耐用性是影響我們選擇組件的關鍵因素。

此外，不僅價格更高的型號受益于德寶 quadral 技術，這些技術僅在德寶 quadral 產品中作為標準配置提供：德寶 quadral RiCom 鋁絲帶高音單元，ALTIMA©和石墨涂層震膜, 壓力腔體設計，BTC 和運行時間校正電路等等..

ENGINEERING

quadral loudspeakers are conceived in such a way that they can handle even difficult amplifiers with ease, which means that you can combine them with virtually any music system.

In the forefront of product development is not only the perfection of individual details but also the minimization of any weaknesses relevant to the sound – graded according to price category. Our aim is not only to harmonize our loudspeakers with diverse music systems, but also with diverse music styles. In doing so, the quality and durability of the materials are crucial factors influencing our choice of components.

Furthermore, not only higher-priced models benefit from quadral technologies which are only available as standard in quadral products: quadral ribbon and RiCom tweeters, quadral-ALTIMA© and graphite-coated laminated membranes, pressure chamber reflex cabinets, BTC and runtime correction circuits, etc..

聲音

Quadral 的第一大發(fā)展目標不是在不同揚聲器之間切換時的最大音量，而是最大的分辨率和與所有可能的放大器的最大兼容性。因此，就聲音的中立性，準確性和對細節(jié)的關注而言，方形揚聲器始終可以在所有正常聆聽位置提供最大的聆聽享受。

盡管許多銷售網點的音響系統(tǒng)反映了不同的理念，但我們在德寶 quadral 有意地調整了揚聲器以匹配典型房屋的音響特性。換句話說，對于面積為15至50平方米，高度為2.2至3 m的矩形房間，包括地毯，窗簾，木制家具，室內裝潢等常見物品。

我們的目標是使您能夠長時間在家中享受德寶 quadral 揚聲器。

SOUND
quadral’s No. 1 development objective is not maximum volume when switching over between different loudspeakers, but rather maximum resolution combined with maximum compatibility with all conceivable amplifiers. Therefore, in terms of sound neutrality, precision and attention to detail, quadral loudspeakers always provide maximum listening enjoyment from all normal listening positions.

Although the acoustics of many sales outlets reflect a different philosophy, we at quadral intentionally tune our loudspeakers to match the acoustic characteristics of typical homes. In other words, for rectangular rooms ranging from 15 to 50 m2 in size, 2.2 to 3 m high and including the usual items like carpets, curtains, wooden furniture, upholstery, etc.
Our aim is for you to be able to enjoy quadral loudspeakers in your home for a long time.

設計

揚聲器必須與各種各樣的環(huán)境協(xié)調一致。因此，幾乎所有德寶 quadral 產品都可提供中性黑色面漆。但是，更高系列的型號也可以提供其他顏色或實木飾面。
我們的風格偏愛主流而不是前衛(wèi)–因此，經典，永恒的線條和音箱飾面均采用最優(yōu)質的材料精心制造，并十分注重細節(jié)。

DESIGN

Loudspeakers must harmonize with a huge variety of surroundings. Therefore, almost all quadral products are available with a neutral black finish. However, models higher up the range are also available in other colours or real wood finishes.
Our styling prefers mainstream to avant-garde – hence the classic, timeless lines and finishes to the cabinets, carefully manufactured using the very best quality materials and much attention to detail..
