Beschrijving
Like listening to one voice rather than many, sound from a single source is inherently clearer. Not only are the acoustic centres of the HF and MF drivers in the Blade & Blade Two Uni-Q array coincident, but the four LF drivers, (225mm/9-in. for Blade, or 165mm/6.5-in. for Blade Two) are mounted symmetrically equidistant from it so that their acoustic centres occupy exactly the same point in space.
This single apparent source configuration is what makes the Blade & Blade Two so gratifyingly coherent across the frequency range, with noticeably more precise imaging than is possible from any conventional speaker.
What you hear sounds as if it’s being performed live right in front of you.
