Product Description

Building on 79 years of extensive experience and knowledge in the industy, the Quad S Series speakers combine advanced Kevlar-coned bass/midrange drivers with a specifically designed ribbon tweeter, supplying seamless audio expression to capture all the details and passion of the original performance. The Quad S4 floorstander supports three-way configurations, coupling a 100mm midrange driver with two 125mm bass drivers.

Advanced Modern Ribbon 

The new ribbon unit developed for the S Series is thoroughly modern and uses the latest techniques and materials. The ribbon has a sandwich construction making it robust enough to handle high-powered amplifiers and is fully immersed in a powerful magnetic field so it accomplishes its dual role of being both the voice coil and the sound radiator.

Tailored Vertical Sound Dispersion

As well as delivering excellent transient response and superb musical detail, the sound from this ribbon unit is smooth right up to the highest musical overtones beyond the limits of human hearing. Controlled directivity maintains this sound quality over a wide horizontal arc to cover all listeners whilst vertical dispersion is tailored to avoid floor and ceiling reflections, resulting in the purest high frequency performance at the listening seat.

Accurate and Articulate Rendition

This ribbon tweeter is aligned with Quad’s Kevlar-coned bass and midrange drivers through sophisticated crossover networks. While the standmount models use carefully tuned, rear-firing reflex ports to augment the bass, the floorstanders are unusual in incorporating three ABRs in place of a port. These passive, rear-firing bass units support the main drivers to extend bass response down to 35Hz whilst maintaining an accurate and articulate rendition of instrument fundamentals.

Reduced Panel Resonance

Beautifully presented with rounded top edges at the front and rear, each speaker cabinet uses a sandwich construction of alternate layers of MDF and high-density particleboard to reduce panel resonance to below the level of audibility.
