Coax 711

The largest model in the PIEGA Coax series, the almost 1.20 m high loudspeaker delivers a superlative sound experience. The coaxial ribbon provides brilliant and detailed highs, silky and clear mid-range and a room-filling sound image.

C211 coaxial ribbon

All high and midrange frequencies are radiated from a point source, thus reaching the listener correctly in phase.

Four subwoofers

The extremely powerful bass of the Coax 711 is due to its large membrane area. Two subwoofers are actively driven and the other two membranes are passively oscillated.

The tension improve modules (TIM) specially developed by PIEGA provide the entire cabinet with a controlled tension and thus prevent even the slightest cabinet vibration.

Aluminium cabinets

Aluminium is the ideal material for loudspeaker cabinets thanks to its outstanding acoustic properties and elegant look.

Elegant design

The highly elegant design with the rounded cabinet shape at the back is timeless and offers a stunning visual highlight in any living room.

Top-class tweeter midrange system

The filigree and incredibly light foils of the Coax ribbon have significantly more surface area and require less movement than the diaphragms of conventional midrange tweeter loudspeakers. This makes the Coax 711 sound incredibly airy, dynamic and impulsive. It also ensures that the frequencies emitted by the coax ribbon always arrive in phase, regardless of the listening position. That’s why PIEGA Coax speakers sound “right” in any room.


We know our strengths. But also those of others. The woofers manufactured by the renowned chassis manufacturer SEAS offer powerful bass reproduction of the highest class. This loudspeaker offers four 220 mm woofers. Two of them are actively driven by the connected amplifier, two resonate passively and support the bass reproduction.
