A famosa unidade unit Q da KEF, com imensas patentes, instalada nas colunas da gama R500.
Em estado impecável.

The KEF SP1632 co-axial Uni-Q driver unit is a 5” 4Ω mid-range driver paired with a 4Ω 1” tweeter placed in the centre of the cone. The SP1632 is used by KEF in the “R Series” loudspeakers. It has a very sturdy and nice build quality, but this driver can’t be used for mid-woofer duties, since it’s a pure mid-range driver and consequently it has to be used in a three way loudspeaker design.

The stiff magnesium/aluminium mid-range cone has special molded braces in the cone in order to control and suppress the mid-range’s cone break-up. The tweeter is mounted in the throat of the mid-range driver and has a “tangerine” wave-guide in front of the dome.

The shape of the mid-range cone, Z-flex surround and driver design ring together with the “tangerine” technology makes a wave-guide for the tweeter, which in turn gives a super smooth tweeter frequency response with a very wide dispersion.
