KEF Q700 Floorstanding Loudspeaker - Rosewood (Single) The Q700 features a specially-voiced 6.25 inch aluminum Uni-Q driver with a 1 inch vented aluminium dome tweeter at its acoustic center, which sits above three 6.25 inch bass drivers. This combination of drivers produces an accurate representation of the human voice, a true reproduction of instrumentation, and undistorted bass that can be exactly as powerful as you want it to be. The drivers' construction, alongside the Q700 cabinet, reduces additional and unwanted bass resonance, meaning you'll never experience muddy bass. The Q700 sits on an aluminum plate supported by four steel 'plinth' spikes with locking knobs for easy height adjustment. The plinths also serve to ground the Q700, resulting in a rigid connection that eliminates any rocking resonances.
