About the C7 ES-3
The Harbeth C7 ES-3 is a two-way vented loudspeaker designed for natural sound reproduction with a focus on neutrality and smoothness. It features a 200mm Harbeth RADIAL2™ cone woofer and a 25mm aluminum dome tweeter cooled by ferrofluid. The speaker has a frequency response of 45Hz to 20kHz ±3dB, an impedance of 6 ohms, and a sensitivity of 86dB at 1W/1m, making it easy to drive with amplifiers from 25W/channel upwards. It handles up to 150W program power. The cabinet is bass reflex type, finished in satin varnish with matched veneer, and measures 520 x 273 x 315 mm, weighing 13.2 kg each. The design includes a single set of gold-plated binding posts and a thin metal frame grille with fabric. The C7 ES-3 is known for its balanced, smooth sound with excellent midrange and good bass extension for its size, making it forgiving on low-quality recordings but less engaging on highly produced tracks. It is optimized for placement away from walls and performs well on stands to bring the tweeter to ear level. The model was produced from 2007 to 2017 and has been succeeded by the C7 ES-3 XD and XD2 versions with improved drivers, crossovers, and cabinet damping for enhanced openness and transparency.
