Floor-standing Speakers

The Quad ESL-2905 are the largest models in Quad's full-range ESL series, featuring six electrostatic panels. The two internal panels use concentric anodic rings to create a point-source image, while the external panels are linear, responding uniformly to the signal. This configuration allows for accurate frequency reproduction, particularly for high frequencies, and provides a wide dynamic response. The total surface area of the panels is designed to ensure good deep bass extension and dynamic reproduction.

The internal components include rare-core transformers and high-quality capacitors, selected to optimize sound quality. To protect the speakers from damage caused by overloads, three protection systems are in place. Additionally, the speaker design is completed with a rigid structure and a total weight of 41.6 kg each, contributing to stable and powerful sound energy transmission, ensuring dynamic and powerful performance.

The Quad ESL-2905 are an example of excellence in electrostatic technology, offering sound reproduction that not only challenges the limits of perception but captures every musical detail. Their full-range electrostatic panel system eliminates the need for a crossover, maintaining tonal consistency across the entire frequency range. The optimized polarizing voltage helps reduce distortion and achieve purer sound, while the dual-panel construction, with the diaphragm suspended between two stators, ensures precise control over the diaphragm movement, maintaining sound quality.

With a frequency response ranging from 32 Hz to 21 kHz (±3 dB), the Quad ESL-2905 are capable of faithfully reproducing the entire sound spectrum, from deep bass to higher harmonics, allowing for extremely detailed musical reproduction. The listening experience provided by these speakers is unique, with a three-dimensional soundstage that enables precise localization of instruments and voices. Every detail of the recording is rendered with crystal-clear clarity, from the singer's breath to the faintest brush of fingers on a guitar string.

Thanks to their dipole configuration, the positioning of the Quad ESL-2905 is very flexible, offering good adaptability to different room configurations.

Unlike many audio technologies that become obsolete quickly, these speakers are designed to last for decades, offering performance that never goes out of style.
