Wharfedale Crystal 4c Center Speaker

Crystal 4c

Crystal 4 series has been engineered for excitement — particularly for movies and music, a Crystal 4 system demonstrates coverage and depth usually associated with much more expensive home cinema systems. Intoxicating high frequencies, powerful bass — it’s mostly thanks to our tried and tested driver technology.

Kevlar is the chosen material for the low frequency drivers in Wharfedale’s leading products— It’s light, stiff and strong. Even our entry level range in Crystal 4 uses a premium Woven Kevlar  weave in its bass and mid drivers (100mm bass driver on Crystal 4.1 bookshelf and a 125mm mid driver on the Crystal 4.3 floorstander). Combined with Wharfedale’s advanced motor systems and in-house manufacturing to guarantee the highest quality, the Crystal 4 delivers speech with clarity and sonic impact for movie special effects.

On the Crystal 4.3 floorstander an additional polypropylene bass driver completes the speaker and again, in-house manufacturing allows proprietary techniques to be used, ensuring the best possible performance. Where inferior polypropylene drivers can distort under the stress of highly dynamic music and soundtracks Wharfedale engineers use a specific technique to reduce this effect. A special Hot Compacted Woven Polypropylene is used, where aligned polypropylene fibres are added in a matrix of thermoformed polypropylene. This results in a much stronger drive unit and therefore lowering distortion, even with large musical peaks.

The Crystal 4 Series also includes the Crystal 4.C centre channel loudspeaker. Possibly the most important speaker in a home cinema system, responsible for approximately 80% of the dialogue, special attention has been paid for an immediate, ‘in the room’ sound with a natural balance. The soft dome tweeter, as seen in all Crystal 4 models ensures a wide dispersion, allowing multiple listeners to experience the same, rich sound-field.

The Crystal 4 Series is finished in a choice of black, white or walnut vinyl wrapped options to match in every home. The Crystal 4.1 also features a rear plate with wall mounting fixture.

華麗璀璨誕生，Wharfedale最新水晶系列第四代劇院喇叭

2014年末Wharfedale發售了最具代表性的主力鑽石Diamond 200系列，連續在國際各大音響媒體獲獎連連，而2016年也如期再發表高階的REVA全鋼烤系列，IAG音響集團不斷為這享譽超過80年的英國揚聲器老字號廠牌注入新活力，從不間斷的研發新技術產品，而過去頗受入門級市場歡迎的Crystal水晶系列也堂堂邁入第四代。

水晶系列暢銷的因素不只是其價格帶因素，真正令消費者垂青的在於其清新舒適的設計，包含箱體外觀及單體的選用，箱體外觀設計為穩定堅固的梯形結構，有效減緩中低音單體發聲運動時產生的共振，讓低頻效果更清晰有力。而單體設計方面，高音與中低音單體連成的招牌水晶型外罩，正是其一貫的視覺符號。而新的水晶四代高音單體改用與鑽石系列同樣的絲質軟半球，取代過去第三代的鈦鐵高音，絲質軟半球的高音表現更為自然通透；中低音單體也由三代的天然纖維升級為鑽石8~10代採用的Kevlar功夫龍單體，在此價位帶顯得特別超值，也更加扎實耐用，足以應付大動態的劇院音效。

水晶四代配合現今居家裝潢潮流，除了傳統經典黑木色外，也推出了與鑽石200系列同樣的雅致白，再搭配搶眼的金黃色中低音單體，摩登與素雅風格相益結合，在超值的預算內同時讓您獲得視覺與聽覺的雙重享受。
