Q750 Floorstanding Speaker

Q750 is the intermediate model for the Q Series floorstanders. Featuring the KEF signature Uni-Q driver array paired with an impressive 165mm (6.5 inch) aluminium bass driver and two matching ABRs, the Q750 delivers astonishing sonic reproduction.

Q750直立式揚聲器

Q750是Q系列產品的中級機款，有著KEF的招牌Uni-Q驅動器陣列，搭配令人注目的165公釐（6.5英吋）鋁製低音驅動器，以及兩個相配的ABR，能夠重現驚人的音效。

"Sit anywhere" Uni-Q sound

At the heart of the evolved Q Series is the Uni-Q driver array. The signature innovation places the tweeter in the acoustic centre of the midrange and bass cone, bringing the acoustic ideal of a single point source closer than ever to realisation. The result is a more detailed, accurate three-dimensional sound image, which is dispersed more evenly throughout the room than is possible with any conventional speaker. Uni-Q's ultra-wide dispersion is further enhanced through KEF's 'tangerine' waveguide over the tweeter dome.

任何位置都可以聆聽最佳效果的 Uni-Q 單體

在先進的Q系列核心，有著Uni-Q驅動器陣列。這個代表性的創新將高音揚聲器置於中音與低音揚聲器的音響中心，讓單點源的聲學理想比以往更接近真實。結果是更細膩精準的3D聲音影像，比任何傳統揚聲器更可能均勻地傳播到整個房間。透過KEF在高音圓頂上方的「冠形導波器」，進一步提升了Uni-Q的超廣域傳播。

Damped tweeter loading tube

With the addition of the damped tweeter loading tube providing a gentle termination of sound produced from the back of the tweeter, lower treble performance is improved dramatically and a new low-distortion inductor on the crossover provides cleaner bass.

緩衝高音載入管

由於附加了緩衝高音載入管，能夠溫和地終止從高音揚聲器後面產生的音響，因此大幅改善了高頻下段的表現，且分音器上的新低失真度電感器提供了較乾淨的低音。

New system design

The closed box midrange cabinet design reduces the load on the Uni-Q midrange cone, increasing clarity and detail while delivering cleaner, punchier bass. Midrange clarity is enhanced again through improvements to the mid-bass driver that allowed the DC blocking capacitor to be eliminated. Its removal also created a more natural bass roll-off between the drivers.

新系統設計

Q 系列落地式喇叭與中央聲道喇叭箱體採密閉式箱體設計，降低了Uni-Q中頻音域錐盆上的負擔，增加了清晰度和細膩度；同時提供更清楚、更靈巧的低音。通過改善中音域的單體的改善 ，進而消除直流阻隔電容的使用， 能再次增強中音域清晰度。另外這個電容器的移除更能在揚聲器單體間創造出更自然的低音效果來。

Beefier LF drivers and ABRs

Low-frequency (LF) drivers now have a larger roll surround, along with a new suspension to produce cleaner bass at high volumes. A new cone structure improves midrange clarity, and an enhanced Auxiliary Bass Radiator (ABR) with a new surround and rear suspension delivers better controlled and more impressive bass.

Beefier LF驅動器與ABR

低頻率（LF）驅動器現在有個更大的滾動式環繞單元，以及一個新的懸吊單元，能夠在較大的音量產生較乾淨的低音。新的錐形結構改善了中音的清晰度，且增大的低音輔助擴散器（ABR）有著新的環繞與後懸吊單元，能傳送控制更得宜且更令人印象深刻的低音。
