LA series crossover settings
Select from the following crossover and filter settings for the LA series of speakers, depending on your
system and application.
•
Bi-amped—LA1, LA2, LA3, LA4 + S115 or S215
•
Tri-amped—LA5 + (2) S215
Bi-amp settings
Low frequency crossover
for subwoofer
High frequency crossover
for speaker
Relative level between speaker and
subwoofer
Subwoofers: S115 or S215
High pass filter: 4th order 24dB/
octave Butterworth at 25Hz
Low pass filter: 24 dB/octave
Bessel at 209Hz
Speakers: LA1, LA2, LA3, LA4
High pass filter: 24 dB/octave
Bessel at 111Hz
Low pass filter: Off (equal to 20
kHz on Digitool)
Relative levels between speaker and
subwoofer at electronic crossover outputs,
as a starting point, before any bulk
equalization adjustments are made:
• LA1 at 0 dB, with S115 at 0 dB
• LA2 at 0 dB, with S215 at -4 dB
• LA3 at 0 dB, with S215 at -4 dB
• LA4 at 0 dB, with S215 at 0 dB
For bi-amp systems, adjust the balance of low and high frequency crossover output levels to achieve
the flattest response for the audio system and environment before using any other equalization.
