9.5.4 Linear Phase Brick Wall 4-Way
The Linear Phase Brick Wall 4-Way (LP4way) uses the processing power of two Modules to create extra-
steep crossovers.

9.6 FIR Module
This module incorporates a combination of FIR (nite impulse response) and IIR (innite impulse response)
technology. The extensive FIR lters can be used to create both crossovers and driver EQ. The phase can be
absolutely controlled rendering linear phase, minimum phase, or arbitrary phase lters. The IIR lters can be
used to create classic crossovers and specic driver EQ.
There are some SpeakerPresets in the Lake LoadLibrary that use the FIR module.
FIR modules supports EAW Focusing through direct import of EAW greybox les into the Lake Controller.
The latest EAW greybox les can be downloaded via: http://www.eaw.com/downloads/
The FIR module cannot be created or congured via the
Lake Controller. A third party software plugin is available for the
Lake Controller; please contact Lake support if you are a loud-
speaker manufacturer and would like further information.
