Description

The Quad Z4 is a floorstanding Hi-Fi solution designed for those seeking uncompromising detail and dynamics. The 3-way bass reflex configuration integrates a 90 x 12 mm true ribbon tweeter , capable of reproducing high frequencies with greater extension and naturalness than traditional dome tweeters. Three 165 mm glass fiber woofers handle the low range with control and energy, while the 150 mm midrange ensures a coherent and detailed midrange.

With a nominal impedance of 4 ohms and a sensitivity of 90 dB , the Quad Z4 is well suited to medium-high power amplifiers (60-250W recommended), offering significant dynamic headroom even in medium- to large-sized rooms. The 47 Hz to 20 kHz frequency response ensures natural extension across the entire spectrum, while dual sets of connectors allow for bi-wiring and bi-amping configurations to optimize signal separation and clarity.

How do you choose a floorstanding speaker that enhances refined systems? The Quad Z4 responds with select materials, optimized crossovers (300 Hz and 3,5 kHz), and an elegant black piano finish , ideal for critical listening environments. The 43-liter enclosure reduces internal resonances and promotes precise airflow control, a key element in the bass reflex design.

Floorstanding or bookshelf speakers: a guide to choosing

Imposing tower or compact bookshelf? It's the question every enthusiast asks at least once, and the answer is never obvious. The choice between floorstanding and bookshelf speakers depends on more than just budget or space...

Anatomy of a Tower: What Makes a Speaker Unique

A floorstanding speaker is built to stand alone, without the need for external supports. Its height—often between 80 and 120 centimeters—allows it to house multiple separate drivers: a tweeter for highs, a midrange driver for midrange, and one or more woofers for bass. This multi-way configuration offers more granular control over different portions of the sound spectrum.
