The 2226J 15" low frequency transducer represents the results of JBL's latest engineering research in high power transducer design. For increased power handling while reducing power compression, a unique direct voice coil-to-air heat dissipation method called Vented Gap Cooling has been used. 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. Through the use of new computer-aided magnet optimization and analysis techniques comes a new weight-optimized Symmetrical Field Geometry (SFG) magnet structure, resulting in a reduction of 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. Specifications: *Power handling: 600 watts RMS *Voice coil diameter: 4" *Nominal impedance: 16 ohms *Frequency Range: 30-2,500 Hz *Magnet assembly weight: 15 lbs. *Fs: 40 Hz *SPL: 97 dB 1W/1m *Vas: 6.2 cu. ft. *Qms: 5.0 *Qes: 0.33 *Qts: 0.31 *Xmax: 7.6 mm *Dimensions: Overall Diameter: 15-1/4“, Cutout Diameter: 14“, Mounting Depth: 5-1/2“.

  • 15" ferrite subwoofer offers 1000Wrms (AES) continuous power handling and a frequency response of 40Hz-2500Hz
  • 4" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression
  • Double suspension and a "multi-roll” surround provide exceptional linearity at extremes of cone excursion
  • Intelligent heat management in both chassis and magnet assembly design further minimises distortion
  • Less than 10kg - very low weight for this product class
