Page 11: Mechanical Safety
Do not stack the loudspeaker array on unstable ground or surface. If the array is stacked on a structure, platform, or stage, always check that the latter can support the total weight of the array. As a general rule, L-Acoustics recommends the use of safety straps at all times. SB10i conguration... -
Page 12: Loudspeaker ConGurations
Loudspeaker congurations Loudspeaker congurations SB10i in standard conguration Deployed in a standard conguration, an SB10i system operates with an omnidirectional directivity pattern over the nominal bandwidth of the SB10i enclosure. The [SB10_100] and [SB10_200] factory presets provide the subwoofer system with an upper frequency limit at 100 Hz and 200 Hz respectively, in order to optimize the acoustic coupling with a main full-range system. -
