About the ESL-2905
The Quad ESL-2905 is a full-range electrostatic floorstanding loudspeaker using eight ultra-light tensioned film panel elements with progressive concentric ring time-delay for phase-coherent, time-aligned sound reproduction. Its heavy-duty aluminium/steel composite frame and rigid three-dimensional support structure (net weight about 41.6 kg) maximise energy transfer and minimise cabinet resonance, while its large dipole radiating area delivers a highly transparent, three-dimensional soundstage with precise imaging.
