The QUAD corner ribbon was a speaker incomparable to competitors at its time, all with thanks to the QUAD ethos, which is still adhered to in all product development and to deliver; “The Closest Approach To The Original Sound”.
Being our first ever commercially available loudspeaker, the Corner Ribbon was not completely perfect – it generated a relatively low power and the ribbon unit was very fragile. As we know founder Peter Walker moved on to develop the world’s first full range, push-pull Electrostatic speaker, if not the most iconic loudspeaker of our time.
So, to make a ribbon unit that handled today’s high power amplifiers and to do the original Corner Ribbon justice was no mean task. The Z Series ribbon accomplishes this by utilising a composite ribbon sandwich substrate that is far more robust than earlier designs and immerses this ribbon in an exceptionally strong magnetic field to yield ultra-high sensitivity.
