Quad Z-4



Unlike conventional dome tweeters where the voice coil motor is attached separately to the diaphragm, Z Series ribbon is both the diaphragm and the motor system. This results is a unique combination of delicacy, smoothness and hear-through performance that helps make your music sing.

Along with this advanced ribbon unit, an equally high performance midrange driver with a unique double -roll-surround and woven glass fibre cone, is especially designed to control edge breakup and give equal transparency to the all important vocal range.

While the bass section utilises an acoustic filter bass reflex system. This eliminates chuffing found in inferior loudspeakers with conventional ports, and helps maintain a natural and unforced reproduction right down to the lowest frequencies of a symphony orchestra, producing Quads signature sound as found in the famous Quad ESL Electrostatic loudspeakers.
