JBL 2220 15-in LF Transducer

Model 2220 is the professional quality low frequency transducer with the greatest possible conversion efficiency. Its combination of a highly efficient magnetic structure and relatively light cone assembly ideally suit the 2220 for use as a bass horn driver, or in arrays of multiple low frequency units. It also will deliver good results in a ported enclosure, but with reduced deep bass response. The unit is offered in 8, 16 and 32 ohm impedances.
