JBL 2206H 12" 600W 8 Ohm Woofer Speaker Driver

The JBL 2206H low frequency transducer represents the results of JBL’s latest engineering research in high power transducer design. The 2206H 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 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 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 was paid to increased mechanical integrity. A new 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 new surround topology and edge damping treatment. The 100 mm (4 in) voice coil benefits from a new 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 acoustic output with lower levels of distortion and smoother response.

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.
