this type of crossover is best suited for subwoofers that can operate linearly up to the 500 Hz range.  Please consult 
your dealer or subwoofer manufacturer to determine if this is suitable for your particular subwoofer.  If the subwoofer is 
capable of handling this range, this is potentially the best sounding of Casablanca III's crossover types. 

 

Phase Perfect Crossover Diagram 

 

Butterworth 

 

This is the most common type of crossover used in home theater, speakers and outboard electronic crossovers.  
Separate high and low pass slopes and crossover frequencies may be set for speaker sets [Left/Right], [Center], 
[Surround Left / Surround Right] and [Center Surround].  (The [Sides] are derived from the L/R Surround channels and 
therefore the configuration and crossover parameters for the sides are set in the L/R Surround sub menu).  As with 
Phase Perfect and Linkwitz-Riley crossovers, it is possible to invert the phase of the low pass for each of these 
speaker sets.  This allows precise tailoring of the subwoofer response to the main speaker's response.  A negative 
attribute of this crossover type is that the high and low pass signals have different phase shifts from each other.

Linkwitz-Riley 

 

This type of crossover, developed in 1976 by Siegfried Linkwitz and Russ Riley, eliminates some of the inherent 
problems of Butterworth filters.  Specifically, a Butterworth filter of 12, 18 or 24 dB/octave (or higher) slope exhibits 
different phase shifts between the high and low pass outputs.  A Linkwitz-Riley alignment solves this problem, as it 
exhibits zero phase difference between outputs at all frequencies.  Acoustically, this means that if the sound sources 
are in proper time-alignment, a smoother frequency response will be realized at the listening position.  The Linkwitz-
Riley crossover is only applicable to slopes of 12 and 24 dB/octave.  A proper Linkwitz-Riley crossover with a 12dB 
slope should have the low pass portion inverted.  This is done internally in the Casablanca III.

A note on crossovers 

 

Casablanca III's complement of crossover options can at first appear daunting.  Most surround sound processors offer 
a simple selection to set their crossovers: Speaker Small or Speaker Large.  When set to small, normally a 
12dB/octave Butterworth crossover is performed at 80Hz.  Occasionally, it is a 24 dB/octave slope.  This simple setting 
does not take into account the huge variations in speaker design and room acoustics and more often than not results 
in non-optimum performance.  We have endeavored to offer this rich set of options with the aim of superior 
performance.  With this in mind, following are a few simple suggestions to make this process easier. 

 

A note on home theater 

 

There are a few common misconceptions about home theater and bass reproduction.  Chief among them is that the 
".1" or "LFE" channel normally contains most or all of the bass information.  This is unequivocally false.  The LFE
