Piega Coax 511 Speakers

For the last 16 years, the Coax series of loudspeakers has been one of the absolute highlights in the PIEGA product range with its combined tweeter and mid-range ribbons. Now the second generation of the Coax series is being launched with the compact bookshelf loudspeaker Coax 311 and the two slightly over one metre high floor-standing speakers Coax 511 and Coax 711. The trio has – as widely used by PIEGA – cabinets made of extruded aluminium, as a result of which the loudspeakers not only look particularly noble and elegant, but are also so stable that there are no performance losses resulting from vibrating cabinet walls.

So-called “Tension Improve Modules” (TIM) are also used in the new Coax loudspeakers, which place the entire cabinet under controlled tension and in this manner prevent even the smallest vibrations in the cabinet. Remaining micro- resonances are completely eliminated by innovative visco- elastic damping films.

The second-generation Coax systems are a further develop- ment of the previously used drivers in all important aspects. The ingenious basic principle of the concentrically arranged mid-range ribbon, at the centre of which the tweeter ribbon is implemented, has been upgraded by stronger neodymium magnets and pole plates made of special high-strength steel with a ferritic structure, thereby achieving a higher level of effi- ciency. The layout of the flat coils under the foil diaphragm and the damping of the foil diaphragm have also been optimised. The new UHQD woofers have titanium voice coil formers, a new suspension and specially formed, coated and extremely rigid aluminium diaphragms. These are also used as passive radiators in the floor-standing loudspeakers.
