Description

Quad has always prided itself as providing the complete solution to music lovers. Each Quad component marries perfectly to other parts of the hi-fi system and is designed with one target – to be ‘The Closest Approach To The Original Sound’. Quad S Series loudspeakers fulfill that objective admirably. Sporting a new ribbon treble unit aligned, through sophisticated crossover networks, to Quad’s advanced bass-midrange drivers, each and every loudspeaker in the range delivers all the nuances and passion of the original performance.

A floor-standing speaker for intimate spaces

Although not physically large as floor-standers go, Quad’s S-4 offers big, spacious, three-dimensional sound. If you like to end your day with a long, relaxed listening session, these speakers make great companions for your musical explorations. One of the keys to the expressive, open sound of Quad’s S Series speakers is their use of ribbon tweeters.

Quad’s ribbon tweeter lets the music flow

The S-4’s ribbon tweeter produces sound in a way that’s simpler and more direct than the more common dome tweeter. 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 amplifier, its resolution of musical detail is extremely high.

Ribbons have always been prized for their pure, clear sound, but they haven’t always been very rugged. Quad’s ribbon tweeter is made from a lightweight metal alloy that is strengthened by a thin layer of polycarbonate. This sandwich construction makes the tweeter robust enough to handle high-powered amplifiers.

The S-4’s tweeter delivers outstanding transient response and reveals loads of musical detail. The sound is “fast,” but consistently smooth. The ribbon tweeter’s shape radiates sound in a wide horizontal arc, while its vertical dispersion is purposely limited to avoid floor and ceiling reflections. That means there’s room in the “sweet spot” for more than one person.

A bass delivery system with precise control

The S-4’s dual 5″ woofers get a big performance boost from three ABRs (Auxiliary Bass Radiators). These passive, rear-firing bass units support the woofers, extending the S-4’s usable bass response.

Although you might be tempted to position the S-4s right up against the back wall to minimize intrusion into your room, you’ll get more open, natural sound by moving them a foot or two out from the wall.
