X8 point source with LF
Deployed as a point source with SB15m subwoofers, an X8 system operates with augmented LF resources.
The [X8] preset allows for a reference frequency response in short throw applications.
The [SB15_100] preset provides the SB15m with an upper frequency limit at 100 Hz for an optimal frequency coupling
with X8.
The X8 and SB15m enclosures are driven by the LA4X / LA8 amplified controllers.
X8 with SB15m
With SB15m, the X8 system contour is reinforced by 8 dB contour at 100 Hz and the bandwidth is extended down to
42 Hz.
