Quad S-1 Speakers
The S-series combines advanced Kevlar-coned bass/midrange drivers with a specially designed ribbon tweeter, supplying effortless detail to capture all the nuances and passion of the original performance.
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.
As well as delivering first rate transients and superb levels of detail, the sound from this ribbon unit is smooth right up to the highest notes 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.
As we expect from Quad the S-1 is beautifully presented with rounded top edges at the front and rear. The speaker cabinets use a sandwich construction of alternate layers of MDF and high-density particleboard to reduce panel resonance to an absolute minimum.
