The Quad S1 is the smallest speaker in the range, but don't let size fool you. These compact bookshelf speakers offer excellent performance with a sweet, open top end and a detailed mid and bass. Beautifully finished in a classic design.
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 fulfil 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.

Furniture Quality Woodwork
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.
Aesthetically, the look is classically Quad, yet subtly updated, available initially in black or sapele mahogany wood veneers. These will be joined in the autumn by premium, hand-laquered piano white and piano black finish options.
Delicate Sound, Powerful Delivery
All S Series models sport a bespoke ribbon treble unit, delivering effortlessly extended high frequencies that are audibly superior to those supplied by typical dome tweeters.
While many ribbon drivers are delicate, easily prone to burning out if overpowered, the new ribbon unit developed for the S Series is a thoroughly modern affair, 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 sound radiator.
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.
