Quad Z-4 Floorstanding Speakers with Ribbon Tweeters & Carbon Fibre Bass Units.
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 in beautifully curved piano lacquered cabinets, available in black, white and rosewood.
It was way back in the mono days of 1949 that Quad launched its first loudspeaker, the Corner Ribbon. This was, indeed, a prestige product, but it offered something special, a particularly clear and detailed upper mid-range to treble performance from a large and delicate ribbon driver.
The naturalness and fidelity of sound reproduction of the original corner ribbon was championed by the hi-fi press. So, the question is, can Quad engineers replicate this performance today, or even surpass it? the answer, not surprisingly, is yes.
Available in piano lacquered black, white, or rosewood, the skillfully veneered, one-piece curved structures make the focal point of any living room.
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.
In the Z Series floorstanders, this advanced ribbon unit is married to an equally high performance midrange driver with a unique double-roll-surround especially designed to control edge breakup and give equal transparency to the all important vocal range.
Both the midrange and bass drivers feature Quad's woven kevlar cone geometry, now matched by the double-roll-surround for the same smoothness and clarity offered by the ribbon treble unit.
The bass section, similar to the original Corner Ribbon utilises an acoustic filter bass reflex system. This section uses a double chamber filter that eliminates “chuffing” found in inferior loudspeakers with conventional ports.
This also maintains a natural and unforced reproduction right down to the lowest frequencies of a symphony orchestra, producing our signature sound as found in the iconic ESLs.
