August 29, 2007 One of the first innovations to be shown at IFA 2007 in Berlin will be a new speaker technology that employs crystal membranes in its quest for perfect sound reproduction. The drive units in the new ELAC 240 series are characterised by stunningly three dimensional soundwave propagation and the new transducer system for bass and midrange uses a highly rigid aluminium membrane with an angled crystalline surface structure.

Combined with extremely wide bandwidth performance, they allow the speakers to acoustically “energize” the room in a consistent and harmonised way. Tolerant of positioning and with an unusually flat frequency response, the 240 series provide a precise and natural listening experience over a wide range of listening positions.

The new transducer system for bass and midrange uses a highly rigid aluminium membrane with an angled crystalline surface structure. This new, ultra tactile, construction not only catches the eye but, when combined with dual coupling of the solenoid to the aluminium sandwich cone, catches the ear with a precise and musical, three dimensional, soundscape.

How fortunate that this advanced three dimensional technology is not just reserved for high end buyers but is available in speakers starting at €498 each.

The 240 series consists of the flagship FS 249 floorstander (starting at EUR 1,998), an additional floorstander, the FS 247 (EUR 998) and the bookshelf speakers BS 244 (EUR 668) and BS 243 (EUR 498), as well as the centre speaker CC 241 (EUR 798) for home cinema use.
