סאבוופר מבית KEF סדרה Q דגם Q400B

Centre, Dipole and Subwoofers
Reproducing most of the soundtrack narrative,
the centre speaker is by far the most important in any home theatre surround
sound system, and the Q200c is engineered accordingly.

With a new generation 130mm (5.25in.) and 165mm (6.5in.) Uni-Q driver
array respectively, flanked by a low distortion bass unit and an ABR of the same size,
they combine raw power with the subtlety to convey moments of great delicacy.
What you notice is how convincingly the larger new metal dome tweeter
captures the emotional range of the human voice – mood and character
shine through with real clarity.
The final ingredient of your new Q system is of course the seductive Q400b subwoofer.
A closed box design housing a 250mm (10in.) woofer driven by a 200W on-board
Class-D amplifier, this discreet cube creates spectacular bass imagery – eloquent,
musical and addictively physical. Anchoring the whole sound
performance in an all-embracing sensation of immediacy, it completes the acoustic picture.
