JBL 2241H low frequency 600WATTS RMS Woofer
JBL 2241H Sub Driver
The JBL 2241G/H low frequency transducer represents the results of JBL’s latest engineering research in
high power transducer design.
The 2241G/H signifies a major advance in speaker design by incorporating JBL’s patented Vented Gap CoolingTM
technology’ in an improved Symmetrical Field Geometry (SFG) magnetic structure.
To increase power handling while reducing power compression, JBL engineers have created a unique,
direct voice coil-to-air heat dissipation method called 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 new computeraided magnet optimization and analysis techniques, JBL engineers were
able to optimize both magnet weight, flux density and field saturation resulting in a 2.6 kg (6.5 lb) reduction
in overall driver weight and a significant reduction in harmonic distortion. This new magnet structure offers
much of the weight advantage of rare earth magnet structures without the prohibitive cost.

Positive voltage on BLACK terminal gives forward diaphragm motion.
AES standard (50-500 Hz).
Sensitivity is based on a swept 100 Hz to 500 Hz signal for an input of 2.83 V @ 8 ohms or 2.0 V @ 4 ohms.
Frequency range is defined as the frequency extremes where the response is - 10 dB from the rated sensitivity.
Power compression is the sensitivity loss at the specified power, measured from 50 to 500 Hz, after a 5 minute
AES standard (50-500 Hz) pink noise preconditioning rest at the specified power.
5Distortion is measured at - 10 dB rated power, from 100-500 HZ
JBL continually engages in research related to product improvement New materials, production methods, and design
refinements are introduced into existing produce without notice as a routine expression of that philosophy. For this
reason, any current JBL product may differ in some respect from its published description but will always equal or exceed
the original design specifications unless otherwise stated.
