The XB21 low frequency transducer is the result of years of R&D to achieve superb performance levels. Designed to Excel in Dual Horns, it has advancements and improvements in all the key areas of transducer technology. Incredibly linear frequency response characteristics, genuinely higher power handling of any comparable transducer, with low power compression. The XB21 features a nano fiber loaded cone assembly, sandwich suspension damper along with optimum excursion constant geometry surround with high Conex fabric and 4 layer Copper 2:2 windings technique VC together provide remarkable strength. Featuring Ideal metal composition for high magnetic flux and low vas requirements good for compact bassline. The high temperature former and forced Linear venting system guarantee a very efficient and less heat voice coil ventilation for minimum power compression and incredible power handling.
