SFG magnet structure with patented* Vented Gap CoolingTMtechnology
The JBL 2206H low frequency transducer represents the industry­leading results of JBL’s engineering research in high power transducer design. The 2206H signified a major advance in speaker design by incor­porating JBL’s patented* Vented Gap Cooling Symmetrical Field Geometry (SFG) magnetic structure.
reducing power compression, JBL engineers 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.
magnet optimization and analysis techniques, JBL engineers were to optimize both magnetic weight, density and field saturation resulting in a significant reduction in harmonic distortion. This innovative magnet structure offers much of the weight advantage of rare earth magnet struc­tures without their higher cost.

1
AES standard (60-600 Hz).
2
Sensitivity is based on a swept 100 Hz to 500 Hz signal. 1 W is 2.83 V @ 8 ohms.
3
Frequency range is defined as the frequency extremes where the response is -10 dB from the rated sensitivity.
4
Power compression is the sensitivity loss at the specified power, measured from 60 to 600 Hz, after a 5 minute AES standard (60-600 Hz) pink noise preconditioning test at the specified power.
5
Distortion is measured at -10 dB power, from 100-500 Hz.
JBL continually engages in research related to produce improvement. New materials, production methods, and design refinements are introduced into existing products 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.

2206H 300 mm (12 in) Low Frequency Transducer
With very high thermal power handling, special attention was paid to increased mechanical integrity. An innovative 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 unique surround topology and edge damping treat­ment. The 100 mm (4 in) voice coil benefits from an innovative winding technique which offers greater thermal stability with increased power handling. All elements of the cone, voice coil and suspension sys­tem have been carefully optimized and controlled to reduce high frequency resonance modes and ensure smooth high frequency response.
The 2206H can directly retrofit the 2204H transducer without enclosure re-tuning while providing up to
2.5 dB more maximum acoustic output with lower levels of distortion.
The high power handling and robust construction of the 2206H is ideally suited for use in touring sound, fixed sound installations, and critical monitoring appli­cations, where high SPL, low distortion and smooth response are required.

Typical response and Impedance Curves, Enclosure Volume and Port Tuning
Frequency response contour of the 2206H taken in a hemispherical free-field environment, a closed box of 280 l (10 ft3) internal volume enclosing the rear of the driver. Measured response of a typical pro­duction unit, including all peaks and dips, does not deviate more than 2 dB from the above curve. The dotted line represents measured 45 degree off-axis response. The dashed curve represents the response when the driver is mounted in a 57 l (2 ft3) vented enclosure tuned to 50 Hz. The impedance magnitude curve is measured in free-air.
Distortion vs. Frequency
Distortion levels raised 20 dB, measured at 60 watts, 1 meter.
