Bowers & Wilkins 685 S2 ลำโพงตั้งพื้น 2 ทาง 6.5 นิ้ว 25-100 วัตต์ 8 โอห์ม
The Decoupled Double Dome Tweeter Found In The 685 S2, And The Rest Of The New 600 Series, Is Technology Taken Straight From Our Award-Winning CM10 Speaker. A Dual-Layer Design Combines A Thin Aluminium Dome For Lightness And A Thicker Aluminium Ring For Rigidity – The Result Is Absolutely Stunning, With Far Greater Clarity In The Audible Spectrum.
The Tweeter Is Also Decoupled From The Main Cabinet, Kept Physically Separate In Its Own Cavity With A Ring Of Gel Cushioning It From Vibrations. This Improves Imaging And Dispersion For A More Natural, Spacious Treble.
As Well As A Decoupled, Double Dome Aluminium Tweeter, The Two-Way 685 S2 Features A Full-Range 6.5-Inch Driver Constructed From Woven Kevlar And Using Anti-Resonance Plug Dustcaps, As Seen In High-End Bowers & Wilkins Speakers. The Result Is Stunning Audio Quality From A Highly Versatile Smaller Speaker.
