Frequency range (-10 dB) 25 Hz - 20 kHz
Recommended ratio 3 K2 : 2 subwoofers
Grouping subwoofers
Place the subwoofer enclosures side by side. If not possible, the maximum distance between two adjacent
acoustic centers must be 2.8m or 1.7m if the upper frequency limit of the subwoofer system is at 60Hz or
100Hz, respectively.
Use [xxxx_xx_C] or [xxxx_xx_Cx] on a reversed subwoofer in a cardioid conguration
The cardioid conguration consists in reversing 1 element in an array of 4 subwoofers.
Refer to the subwoofer owner's manual and to the Cardioid congurations technical bulletin.
Delay values
Do not forget to add the pre-alignment and geometric delays depending on the conguration.
When using [K2 70], [K2 90], or [K2 110] with [K1SB_X K2], do not add any delay value between the K2 and
K1-SB elements of a same line source.
