X12 point source with LF
Deployed as a point source with SB15m or SB18 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] and [SB18_100] presets provide the SB15m and SB18 with an upper frequency limit at 100 Hz for an
optimal frequency coupling with the X12.
The X12, SB15m and SB18 enclosures are driven by the LA4X / LA8 amplified 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.
