Finally, to match the improved dynamics of the ESL elements, the mechanical aspects of the speakers have been enhanced. A new net cloth has been chosen to cover the elements which allow superior audio transparency as well as improving the appearance of the speakers. The underlying grille support has revised strengthening ribs to reduce the possibility of resonance as well as to ensure the grille cloth remains under tension without stretch marks.
To distinguish the 2812 and 2912 from their predecessors, there are cosmetic changes too. These changes improve the look of the speakers in domestic surroundings. As well as the new grille cloth, there are matching piano lacquered veneered panels on the top of the speakers and the sides of the base formed from high-density plywood to further damp frame resonances.
The shielding cover on the base is embossed with the QUAD logo and all typography is now gold lacquer paint.
