Subwoofer loudspeaker enclosures presets
In this section, tables describe the loudspeaker congurations for L-Acoustics versatile subwoofers, and the corresponding
factory presets. Discriminant acoustic properties of each loudspeaker conguration are given, such as -10dB bandwidth
or LF limit, or directivity specicity.
Headroom for SB15m
SB15m presets [SB15_100] and [SB15_100_C] have 8 dB of headroom from preset library version 5.6(.5).
[SB15_100_Cx] has 8 dB of headroom.
4 dB of headroom are provided when using presets from earlier versions and preset [KIVA_SB15].
Headroom for K1-SB, KS28, SB28, SB18, SB218 and SB118
To provide 8 dB of headroom, the output gain of some subwoofer presets is adjusted in preset library 6.0
compared to previous versions.
This update aligns the L-DRIVE activity between subwoofers and full range loudspeakers for the same reference
pink noise signal.
When updating presets in Session les using older versions of the preset library, adjust gains as follows to keep
the same gain chain:
[SB28_60], [SB218_60]: + 4 dB
[KS28_60], [SB_28_100], [SB18_60], [SB18_100], [SB218_100], [SB118_60], [SB118_100]: + 3 dB
[KS28_100]: + 2 dB
[K1SB_60]: + 1 dB
