JBL 2241-H 18In Low Freq Cone Transducer-8Ohm
JBL 2241-H 18″ Low Freq Cone Transducer – 8 Ohms
The JBL 2241H low frequency
transducer represents the results of
JBL’s industry-leading engineering
research in high power transducer
design. The 2241H signified a major
advance in speaker design by incorporating JBL’s patented Vented Gap
Cooling technology in an improved
Symmetrical Field Geometry (SFG)
magnetic structure.
To increase power handling while
reducing power compression, JBL
engineers created a unique method
called direct voice-coil-to-air heat dissipation (Vented Gap Cooling). This
process pumps air through the magnetic gap and directly over and
around the voice coil to provide
immediate heat transfer and reduction
in operating temperature – a direct
improvement in power compression.
Through the use of computer-aided
magnet optimization and analysis
techniques, JBL engineers were able
to optimize both magnet weight, ux
density and eld saturation resulting
in a significant reduction in harmonic
distortion. This new magnet structure
offers much of the weight advantage
of rare earth magnet structures without the higher cost.
With very high thermal power handling, special attention was paid to increased mechanical integrity. A new
cone design which greatly improves cone strength allows
for increased reliability and longer life. Greater linear
excursion for matched power and displacement levels was
achieved via a new surround topology and edge damping
treatment. The 100 mm (4 in) voice coil benefits from a
new winding technique which offers greater thermal stability with increased power handling. All elements of the
cone, voice coil and suspension system have been carefuly optimized and controlled to ensure smooth high frequency response.
The 2241H is ideally suited for use in touring and fixed
sound applications where high SPL and deep bass
response are required. Its low distortion and smooth
frequency response make the 2241H suitable for critical
monitoring applications as well.
