    Syva colinear source In this configuration the system operates over the nominal bandwidth of the enclosure. The [SYVA] preset allows for a reference frequency response in medium throw applications. Syva is driven by the LA4X / LA8 / LA12X amplified controllers.

  • Page 10: Syva Colinear Source With Lf Extension

    Loudspeaker configurations Syva colinear source with LF extension In hybrid configuration with Syva Low, the Syva system bandwidth is extended down to 40 Hz and the system contour is reinforced by 9 dB. Syva and Syva Low are driven by the LA4X / LA8 / LA12X amplified controllers.

  • Page 12: Syva Colinear Source With Lf Extension And Subwoofer

    Syva, Syva Low and Syva Sub are driven by the LA4X / LA8 / LA12X amplified controllers. Coupled The [SYVA LOW SYVA] hybrid preset enables acoustic coupling when Syva is on top of Syva Low (AutoConnect) or within a 60 cm (24 in) distance.
  • Page 13 Separated The [SYVA] preset allows for a reference frequency response in medium throw applications. The [SYVA LOW_100] and [SYVA SUB_100] presets provide Syva Low and Syva Sub with an upper frequency limit at 100 Hz. [SYVA SUB_100] polarity is reversed to optimize Syva Sub acoustic summation with Syva/Syva Low.
