QUAD proudly announce Z Series, our new flagship ribbon loudspeaker range. After taking a new approach to ribbon tweeter design using a unique sandwich formation, an exceptionally robust, high power speaker has been engineered, yet with the delicate sound conventional ribbon speakers are known for. Z Series is housed beautifully curved piano lacquered cabinets, available in black, white and rosewood.
Then And Now
The Quad corner ribbon was a speaker incomparable to competitors at it’s time, all with thanks to the Quad ethos, which is still adhered to in all product development and to deliver; “The Closest Approach To The Original Sound”.
Being our first ever commercially available loudspeaker, the Corner Ribbon was not completely perfect - it generated a relatively low power and the ribbon unit was very fragile. As we know founder Peter Walker moved on to develop the world’s first full range, push-pull Electrostatic speaker, if not the most iconic loudspeaker of our time.
So, to make a ribbon unit that handled today’s high power amplifiers and to do the original Corner Ribbon justice was no mean task. The Z Series ribbon accomplishes this by utilising a composite ribbon sandwich substrate that is far more robust than earlier designs and immerses this ribbon in an exceptionally strong magnetic field to yield ultra-high sensitivity.
The Ribbon Tweeter
Unlike conventional dome treble units where the voice coil ‘motor’ is attached separately to the diaphragm, Z Series ribbon is both the diaphragm and the motor system. The result is a unique combination of delicacy, smoothness and hear-through performance that helps make your music sing.
While taking influence from the unparalleled success of the ESL speaker, the ribbon itself is engineered to be extremely light and thin, which delivers the startling accuracy and wide coverage Quad is famous for.
In our flagship series, the larger 90 x 12mm true ribbon creates an even higher sensitivity and bandwidth which means better dynamics and an even smoother integration with the midrange frequencies.
