X4i point source with low-frequency element

Deployed as a point source with Syva Sub or SB10i subwoofers, an X4i system operates with augmented LF resources.
The [X4] preset delivers a reference frequency response in short throw applications.
The [SYVA SUB_200] and [SB10_200] preset provide Syva Sub and SB10i with an upper frequency limit at 200 Hz.
X4i, Syva Sub, and SB10i are driven by the LA2Xi / LA4X / LA8 / LA12X amplied controllers.

X4i point source with Syva Sub

With Syva Sub, the bandwidth of the X4i system is extended down to 29 Hz and the system contour is reinforced by
7 dB at 50 Hz (peak low-end SPL).
