Quad S1 Black Pair

Quad's new S series loudspeaker range marks 79 years since the company's inception. Each model combines advanced Kevlar-coned bass/midrange drivers with a specially designed ribbon tweeter, supplying effortless sonic expression to capture all the nuances and passion of the original performance.

Cutting Edge Techniques and Materials
Just 285mm high, the Quad S1 incorporates a 100mm bass/mid cone and the new ribbon unit developed for the S Series is thoroughly modern, utilising the latest techniques and materials.

The ribbon itself is a sandwich construction, making it robust enough to handle high-powered amplifiers, and is fully immersed in a powerful magnetic field so that it accomplishes its dual role of being both the voice coil and the sound radiator.

 

Impressive Transient Response
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 (Auxiliary Bass Radiators) 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 the instruments.

High Density Particle Board
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.

Closest Approach To The Original Sound
Commenting on the design of the S Series, Peter Comeau, Director of Acoustic Design at Quad’s parent company IAG, said: “S Series speakers are fashioned to reveal all the delightful inner detail of whatever style of music is played through them, yet exhibit a full and dynamic performance, even from the tiny S1, that exemplifies Quad’s dictum of ‘The Closest Approach To The Original Sound’.”
