JBL 2206H 12" 300 mm (12 in) Low Frequency Transducer
The JBL 2206H/J low frequency transducer represents the results of JBL's latest engineering research in high power transducer design. The 2206H/J signifies 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 whilereducing power compression, JBLengineers have created a unique,direct voice coil-to-air heat dissipationmethod called Vented Gap Cooling.This 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 compression.
Through the use of new computer-aided magnet optimization and analysis techniques, JBL engineers were able to optimize both magnet weight,flux density and field saturation resulting in a 1.8 kg (3.9 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 their prohibitive cost.
With increased power handling, special attention waspaid to increased mechanical integrity. A new cone designwhich greatly improves cone strength allows for increasedreliability and longer life. Greater linear excursion formatched power and displacement levels was achieved viaa new surround topology and edge damping treatment.The 100 mm (4 in) voice coil benefits from a new windingtechnique which offers greater thermal stability with increased power handling. All elements of the cone, voicecoil and suspension system have been carefully optimizedand controlled to reduce high frequency resonancemodes and ensure smooth high frequency response.
The 2206H/J can directly retrofit the 2204H transducerwithout enclosure re-tuning while providing up to 2.5 dBmore acoustic output with lower levels of distortion andsmoother response.
The 2206H/J is ideally suited for use in touring sound, fixed sound installations, and critical monitoring applications, where high SPL, low distortion and smoothresponse are required.
