Three basic enclosure volumes offered are 320, 420, and 530 liters. The table below shows low frequency capability of each cabinet size/tuning combination beyond the above quoted specification. Sealing one port lowers system tuning with a 2dB loss in sensitivity. Flat response to 20Hz can be achieved in any configuration with a slight decrease in power handling by installing the Low Frequency Contour option in the SDX Crossover. |
