About the Quad Z-1

Quad's ribbon tweeter sounds exceptionally smooth.

Quad's Z series combines upscale sound and looks

Normally, I don't pay too much attention to how a speaker looks, but the sculpted curves and lacquered finish of Quad's Z series really caught my eye.

Using multi-layered construction, the Z-1's compact, rounded enclosure curves all the way around the back from one side of the baffle to the other. It's stylish, and helps reduce internal standing waves, for uncolored sound.

The ribbon tweeter is the star

Most home speakers use a dome tweeter to handle high frequencies. A much rarer approach is the ribbon tweeter, but you'll find one in every Quad speaker we sell. The ribbon in their flagship Z series speakers is twice as tall as the one in their S series, for greater dynamics and even smoother blending with midrange frequencies.

In a dome tweeter, the signal from your amplifier drives a voice coil, which is connected to the dome-shaped diaphragm, but only around the circumference, so a bit of musical information may be lost.

In a ribbon tweeter, the metal ribbon is suspended in a strong magnetic field. Basically, the diaphragm is the voice coil, so it's always under the control of the music signal from the amplifier. Because the ribbon is directly driven by the amp, its resolution of musical detail is extremely high.

From the Sound & Vision review


"The Z-1 is both warm and revealing. Ordinarily, that might be a paradox; sometimes, warm-voiced speakers are hiding something, or at least sugarcoating the truth. But Quad's ribbon tweeter mustered its golden glow while simultaneously opening a big, clear window into instrumental and vocal color and texture. It conjured bold, detailed images in the prime listening position — but also did so off axis. The result can be more physically relaxing than with some other designs because you needn't hold yourself as rigidly in the sweet spot.”

— Mark Fleischmann, Sound & Vision, August 2016

The Z-1's woofer is in control

The Z-1 relies on a 5-7/8" woven-Kevlar® mid/bass driver to handle the mid and low frequencies. The woofer is reinforced by an “acoustic filter” bass-reflex cabinet design with a rear port that employs an expansion chamber filled with resistive foam. You get the best of both worlds: the sensitivity and extension of a bass-reflex speaker, and the clarity and quick response of a sealed box.

Setup tips

The ribbon tweeter's shape radiates sound in a wide horizontal arc, while its vertical dispersion is purposely limited to reduce interaction with the floor or ceiling. So, it's especially important to position the speakers so that the tweeters are at ear level. Using 24" stands should do the trick in most systems.

To hear the Z-1s at their best, try to drive them with at least 50 watts per channel of high-quality amplification. And as with any compact, high-quality speakers, I suggest pairing these with a high-quality subwoofer for truly full-range sound.

Quad's history of innovation

Founded in 1936 to build public address systems, Quad introduced two of the most important speaker innovations of the past century: the first ribbon-based home speaker, in 1949, and the first full-range electrostatic speaker, in 1957. Today, Quad speakers and electronics are still designed and engineered in England, and are manufactured in China.
