•quadral QUBE 8 AKTIV 超低音 規格表

BASS THUNDERSTORM
Sound perfection. The low sound of a contrabass, the dark resonating beats of a kettle drum, the dull rumble of the storm, and often a resultant thunderous shake – it is often the subwoofer, which brings the experience to life. To render the low frequencies powerfully, membranes, cabinet, and electronics and their interplay were developed specifically for the job.

A quadral subwoofer relieves the other speakers in the array, allowing them to then concentrate completely on the mid and high frequencies while the subwoofer drives that low end – with detailed precision, speed and depth.

QUBE 8 AKTIV
A TRUE BASSIST
This compact subwoofer can quake the floor. Its meagre dimensions make it almost invisible in the listening room, but you can’t miss the power conjured up by the 220 mm long-stroke woofer.

Facts
Supported by a bass reflex channel, and of a ‘downfire’ design, the Qube 8’s potent output stage produces bone-dry accents in the lower bass range. It doesn’t matter whether musical subtlety or powerful home theatre sound is needed — the Qube 8 is a true universal genius, plus soft clipping and a peak limiter are there just in case life gets a little too exuberant.
