The2226G/H/J signifies a major advancein speaker design by incorporatingJBL s patented Vented Gap Cooling technology in an improved Symmetri-cal Field Geometry (SFG) increase power handling whilereducing power compression, JBLengineers have created a unique,direct voice coil-to-air heat dissipationmethod called Vented Gap process pumps air through themagnetic gap and directly over andaround the voice coil to provideimmediate heat transfer and reductionin operating temperature - a directimprovement in power 2226G/H/J incorporates animproved SFG (Symmetrical FieldGeometry) magnetic magnet optimizationand analysis has allowed JBL engi-neers to optimize both magnet weightand flux density so that the 2226G/H/Jis not only kg ( lb) lighter thanits predecessor, but has reduced dis-tortion as well.

New materials, production methods, and designrefinements are introduced into existing products without notice as a routine expression of that philosophy For thisreason, any current JBL product may differ in some respect from its published description but will always equal or exceedthe original design specifications unless otherwise stated 2226G/H/T 380 mm ( 15 in ) Low Frequency TransducerIncreased power handling also requires greatermechanical integrity.

4 A new cone design greatly improvescone strength and stiffness-to-weight ratio through theuse of a new glass fiber/paper composite cone new surround topology and edge damping treatmentallow greater linear excursion for matched power anddisplacement levels. The voice coil benefits from a newwinding technique which offers greater power handlingand thermal stability. All design aspects of the surround,cone and voice coil have been carefully optimized andcontrolled to provide smooth and extended highfrequency 2226G/H/J can directly retrofit the 2225H/J trans-ducer without enclosure re-tuning while providing up to4 dB more acoustic output with lower levels of high power handling and robust construction ofthe 2226G/H/J make it a natural for tour sound and fixedsound reinforcement use, while the low distortion andsmooth response make it an ideal choice for critical highlevel monitoring PARAMETERS6:f.
