In response to the demand for increased subwoofer directivity control, L-Acoustics has developed the Cardioid Extended preset library. This new “Cx” library is a factory optimised solution offering broadband rear SPL cancellation with limited compromises on front SPL and time response[1].
As for the Cardioid C classic configuration, the Cx Cardioid Extended configuration is obtained by reversing one enclosure per group of three or four subwoofers [2] and simply applying the dedicated Cx preset. Engineers benefit from a plug-and-play solution that saves both time and effort during system calibration. The new Cx library is available in LA Network Manager 2.7.3 for SB15m, SB18(i/m), SB28, KS21 and KS28 subwoofers.
1. In comparison to classic broadband rear SPL cancellation cardioid techniques.
2. Reversing one enclosure per group of two subwoofers is also possible but reduces the front SPL efficiency
