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.

Tri-amp settings

Low frequency
crossover for
subwoofer

Mid-frequency
crossover for
speakers

High-frequency
crossover for
speakers

Relative level/delay
between speaker and
subwoofer

Subwoofers: (2) S215
High pass filter: 24dB/
octave Butterworth at
25Hz

Speaker: LA5 mid-input
High pass filter: 24 dB/
octave Bessel at 111Hz
Low pass filter: 24 dB/
octave L-R at 1.5kHz

Speaker: LA5 high input
High pass filter: 24 dB/
octave L-R at 1.5 kHz
Low pass filter: Off (equal
to 20 kHz on Digitool)
