Quad Say….
Quad has drawn upon its expertise with electrostatic loudspeakers to design its first-ever pair of headphones – the ERA-1.
To ensure a natural sound in keeping with the company’s heritage, QUAD’s engineers have developed a planar magnetic driver delivering fast, open and transparent performance, similar in quality to the famous ESLs.
Most headphones use mass-produced dynamic cone drivers, the limitations of which can hamper transient response and cause an uneven frequency response. QUAD’s cutting-edge planar magnetic technology delivers a more natural and accurate sound, ensuring you hear every nuance of a recorded musical performance.
The QUAD ERA-1 incorporates an ultra-thin, electrically active diaphragm – thinner than a human hair yet extremely strong and highly elastic, weighing less than the volume of air it displaces. This is fused with a precisely arranged magnet array, designed to maximise sensitivity and consistency of the applied force over the driver area.
Patented nonlinear vibration suppression technology allows the driver’s effortlessly extended frequency response to be heard unsullied, ensuring perfect clarity. The metal cavity behind the driver is specially designed for optimal acoustic performance, and the drivers themselves are closely matched to ensure spacious, three-dimensional stereo imaging. The result is that ERA-1 provides a musically engaging, dynamic and effortless sonic performance that suits all types of music.
High-resolution sound, teeming with musical expression – the ERA-1 headphones submerge you in the performance of your favourite musicians with direct and engaging intimacy. Once again, QUAD delivers ‘the closest approach to the original sound’, bringing you up close and personal to the music you adore with beguiling clarity and definition.
