ELAC FS 249 User Manual

FS 249: When striving for perfection, you must break new ground
Experience music, be right in the middle
of it, soak up the atmosphere, “see”, feel
and sense each instrument, each voice –
this is how speakers should reproduce
music.
In order to reproduce music authentically,
vividly and naturally, the ELAC R&D
engineers have paid special attention to
three-dimensional sound radiation
patterns. Their aim: to acoustically
“energize” the room in a consistent and
harmonised way.
To this end, ELAC has developed new
transducer systems for the bass and
midrange, and has calibrated the
crossover frequency to optimise sound
radiation characteristics across the entire
frequency range. The result is a uniquely
precise and musical three dimensional
soundscape.
Technical features and
characteristics:
• The design of the new patent-
pending woofer is based on the
renowned ELAC aluminium
sandwich technology which, by
combining the different resonant
characteristics of cellulose and
aluminium, leads to a marked
reduction in harmonic vibrations.
• The crystal-like surface of the new aluminium membrane catches both the eye & the ear. Harmonic vibra-
tions are significantly reduced by the angled crystaline surface structure. In addition, by using a press
formed structure, the membrane is more rigid and has lower distortion which not only prevents partial vi-
brations in the crossover zone but also reduces harmonic distortion.
Due to the high rigidity of the
aluminium membrane, it is
now possible to attach the
solenoid not only to the cone
neck but also directly to the
aluminium membrane. This
significantly extends the
cone’s bandwidth right across
the frequency range giving a
noticeably more even &
continuous frequency
response.
