X12 point source with LF
Deployed as a point source with SB15m, SB18 or KS21 subwoofers, an X12 system operates with augmented LF
resources.
The [X12] preset allows for a reference frequency response in short throw applications.
The [SB15_100], [SB18_100] and [KS21_100] presets provide the SB15m, SB18 and KS21 with an upper frequency
limit at 100 Hz for an optimal frequency coupling with the X12.
The X12, SB15m, SB18 and KS21 enclosures are driven by the LA4X / LA8 / LA12X amplied controllers.
X12 with SB15m
With SB15m, the X12 system contour is reinforced by 8 dB at 100 Hz and the system bandwidth is extended down to
40 Hz.

Delay values
Do not forget to add the pre-alignment and geometric delays depending on the conguration.
