About the Quad Z-3

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 cool "disappearing act" where you're not really aware of the sound coming from two boxes. But the sophisticated ribbon tweeter in Quad's Z-3 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 cool "disappearing act" where you're not really aware of the sound coming from two boxes. But the sophisticated ribbon tweeter in Quad's Z-3 makes it easy to forget about the speakers and just get lost in the music.

The Z-3's multi-layered construction and curved enclosure create a stylish look, and help reduce internal standing waves, for clear, 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 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-3 features a 5-7/8" woven-Kevlar® midrange driver to handle that crucial band of frequencies that includes vocals. The dual 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.

Features

Ribbon Tweeter: Unlike conventional dome tweeters where the voice coil "motor" is attached separately to the diaphragm, the Z Series ribbon tweeter is both the diaphragm and the motor system. Utilizing a composite ribbon sandwich substrate that is engineered to to be extremely light and thin, the Z-3 floorstanding loudspeaker delivers startling accuracy and a broad soundstage. This unique sandwich formation designed 0.5" x 3.5" ribbon tweeter also produces higher sensitivity, wider bandwidth, and greater dynamics for high resolution audio.

Woven Kevlar Midrange & Woofers: The 5.875" midrange driver and dual 6.875" woofers feature Quad's woven kevlar cone geometry, now matched by a double-roll-surround to control edge breakup and produce the same level of smoothness and clarity in the mid and bass frequencies as offered in the high frequencies by the ribbon tweeter.

Curved Ported Cabinet: The Quad Z-3 floorstanding loudspeaker features a bass reflex design enclosure with a rear-firing port for greater efficiency and bigger bass response without "chuffing" or port noise. The speaker cabinet is a skillfully, engineered one-piece curved structure that prevents internal standing waves and aids in broader sound dispersion. Available in a black, white or rosewood lacquer finish. Includes a magnetically attached black cloth grille.

Dual Binding Posts: The Z-3 floorstanding loudspeaker has two sets of binding post terminals connected by metal straps. The binding post terminals will accept bare wire (up to 10AWG), pin connectors, spade-lugs, and banana plugs (single only). Using the dual binding posts, you can bi-wire or bi-amp the speaker. Bi-wiring or bi-amping the speaker provides improved bass & treble performance. The binding-post speaker terminals are color-coded (red+/black-) and are at floor-level for easy identification and hookup.

  • Bi-Wiring: Bi-wiring can provide noticeable improvements in the overall transparency of your loudspeakers. Run separate speaker wires to the low & high frequency drivers from a single amplifier (the upper set of binding posts are for the high frequency drivers; the lower set of binding posts are for the low frequency drivers).
  • Bi-Amping: Bi-amping allows you to use separate amplifiers for the high & low frequency sections of your loudspeaker for greater dynamic range & lower distortion. We recommend that your separate amplifiers have identical gain to preserve the speaker's voicing balance.
Note: If you decide to bi-wire or bi-amp the speaker, you must remove the jumpers between the terminal posts (failure to do this could result in damage to your amplifier and loudspeakers).

Mounting & Placement Options: The Quad Z-3 floorstanding loudspeakers included spike feet that thread into the bottom of the speaker cabinet. The spike feet are adjustable so you can level the speaker. The spike feet are best for carpeted flooring. The spike feet will scratch hardwood, tile, vinyl, and laminate flooring. Make sure to place protective discs (not included) under the spike feet to prevent damage to your hard surface floors.

  • A pair of Quad Z-3 floorstanding loudspeakers should be placed between 6.5' and 9.8125' apart and equidistant from the main listening position. The loudspeakers should be positioned so that they are angled slightly inward, facing the listener.
  • The most uncolored sound will be obtained when the speakers are at least 7.875" from the rear walls and 11.8125" from the side walls. If the loudspeakers are operated closer to the rear walls the bass will increase, but if they are placed to close to the walls the bass may sound too "boomy" and non-distinct. If the loudspeakers are placed further away from the walls, the inward angle can be increased by up to 40%, although this may restrict the width of the optimum listening position.

Note: The spike feet should always be utilized for optimum stability and sound performance.

Z Series: Z Series is Quad's new flagship ribbon loudspeaker line-up. After taking a new approach to ribbon tweeter design using a unique sandwich formation, an exceptionally robust, high power speaker has been engineered that still offers the delicate sound, conventional ribbon speakers are known for. The Quad Z Series consists of two floorstanding loudspeakers (Z-3 / Z-4) and two bookshelf loudspeakers (Z-1 / Z-2).
