At the heart of the Coax 811, the C212+ coaxial ribbon emits the treble and midrange from a single point. It delivers brilliant highs and a clear, silky midrange. The frequencies reach the listener in phase, for a precise and airy soundstage.
Four 22 cm UHQD bass drivers equip the Coax 811: two active woofers and two passive radiators. Made by SEAS to PIEGA's specifications, they deliver a dynamic, deep bass. This three-way system reaches down to 22 Hz.
The one-piece extruded aluminium cabinet provides remarkable rigidity. The TIM2 module places the panels under controlled tension to neutralise resonances. The design by Stephan Hürlemann stands out as a focal point in the room.
The Coax 811 comes in silver aluminium, black anodised and white lacquer, plus eight Coax Excellence shades such as Blue Lagoon, Misty Green or Alpine Stone. Its 92 dB sensitivity and 4-ohm impedance suit amplifiers from 20 to 250 watts. It measures 124 x 29 x 42 cm for 63 kg.
