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

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.

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.

Thiele/Small parameters are measured after 2 hour exercise period using a 600 W AES
power test and will reflect the expected long term parameter values once the driver has
been installed and operated for a short period of time.

Clearance of at least 76 mm (3 in) must be provided behind the magnet assembly and
the gap vents to allow sufficient air circulation and proper cooling to take place.

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.
