About the Quad Z-4

Quad's Z series combines upscale sound and looks

Compared to compact bookshelf speakers, it can be difficult for floor-standing speakers to pull off that "disappearing act" where you're not really aware of the sound coming from two boxes. But the sophisticated ribbon tweeter in Quad's Z-4 makes it easy to forget about the speakers and just get lost in the music.

Quad's Z series combines upscale sound and looks

Compared to compact bookshelf speakers, it can be difficult for floor-standing speakers to pull off that "disappearing act" where you're not really aware of the sound coming from two boxes. But the sophisticated ribbon tweeter in Quad's Z-4 makes it easy to forget about the speakers and just get lost in the music.

When I tried out a pair of Quads at home for a few weeks, I felt like I could hear every bit of detail on every recording, but the sound was always super smooth and completely non-fatiguing.

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 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. 

Bass response that's the best of both worlds

The Z-4 features a 5-7/8" woven-Kevlar® midrange driver to handle that crucial band of frequencies that includes vocals. The three 6-7/8" woofers are made of the same material, and are 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.

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.
