|1% full power||LF||.09 / .30%|
|10% full power||LF||.14 / .48%|
|Crossover point range, 4th order @ 24dB/octave with SDX Crossover|
|HF||Useable to 1500Hz|
|MF||Low pass with SD 312 @ 80-110Hz|

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.
