ELAC FS 247 Sapphire Edition


"The whole sound from the properly three-dimensional imaging to the driving rhythm was incredibly cohesive and enjoyable. ELAC's gorgeous FS 247 Sapphires are simply masters at capturing the whole picture, from the inflections in BB King's accent to the smooth slide quitar and warm ambience of the recording studio"

Hi-Fi News (UK) review


"Sound is unusually light, is detailed, is plastic, is air, as if hovering. The sensation of very thin sound recording appears. If we allow analogy with the painting, then these are water color or pastel. The sonic means of model is very well designed. It is beautiful, holographically precise, elegant according to figure, is volumetric, transparent musical scene. The pair of compact floorstand loudspeakers with the small midbass drivers produces to the surprise influential, subjectively sufficiently deep, very well designed in tone and temporary sense..."

Stereo & Video (Russia) review


"... Should your biases or tastes favor a laid-back bodacious sound, an audition with the ELAC FS 247 will likely not end in merry toasts of brotherhood - but the speaker would feel the same about you. The 247's character is unequivocal and clearly carries the maker's imprimatur of philosophy and design brief, a statement of purpose I cherish in products. In this case, the aim was to create a speaker of extraordinary staging, timing and high resolution for a direct, energetic, intense listening experience - with mission patently accomplished. Compared to other speakers with similar virtues, ELAC's FS 247 offers pronounced long-term utility not least because of its special tweeter. Considering the asking price, this package of qualities is anything but common. Ideally, you'd not leash this speaker to components or cables suspected of undue bite or sharpness since such matters would be magnified by a transducer of this caliber accuracy."

Treble Unit

JET III used in all 240 Series range.

ELAC FS 247 Sapphire Edition - JET III tweeter

The ELAC JET tweeter is one of the most legendary tweeters in the hi-fi trade and has won international renown with its unusual transparent and effortless sound image.

The JET tweeter was delveloped to perfection on the basis of the famous 'Air Motion Transformer' by loudpseaker pioneer Dr Oskar Heil. Its principle: a concertinaed foil membrane is driven by a strong magnet system of neodymium rods.

This 'motor' drives the air considerably faster than the conventional pistonic technique. High sensitivity and extraordiary dynamics are the result. Due to continuous improvement, the JET III tweeter creates an effortless and airy resonance-free image up to 50,000 Hz, and with its linear frequency response is ideally suited for the reproduction of Hi-Res Audio music.

ELAC JET DC (Dispersion Control) ring
ELAC JET DC (Dispersion Control) ring
The ELAC "JET Dispersion Control DC" is a flat ring made of open-cell rubber foam which is mounted around the JET orifice with four clasps (or with adhesive tape).

The JET DC results in a broadband reduction of about 0.5 dB of the radiated sound level nearly independent of frequency. The JET DC is best suited for rooms with little sound absorption at high frequencies, especially for rooms with large windows without curtains or with a smooth floor without a carpet.

All loudspeakers of the 240 series are supplied with the JET Dispersion Control as an accessory.


Midbass Unit

TT 150 AS-XR sapphire midbass used in: FS 247 SE.

All woofers and midrange drivers of the 240 series contain the new "Crystal Membrane" (patent pending) and their design is based on the well-known "Aluminium-Sandwich AS Technology" which was developed by ELAC a couple of years ago. The crystal-shaped inverse aluminium dome is joined to the paper cone in a special glueing process resulting the desired sandwich construction.

The stamping of the aluminium foil looks like the surface of a large crystal, this is where the term "Crystal Membrane" come from. This stamping stiffens the aluminium dome considerably which diminishes the membrane-internal resonances resulting in less sound coloration and additionally improves the large signal behaviour noticeably.

The voice coil is not only - like usually - joined to the neck of the paper cone but also to the bottom of the aluminium dome. This design results in the expansion of the transmission range of the respective woofers or midrange drivers by nearly an octave. Therefore the abbreviation "XR" (eXtended Range) has been introduced.
