Kicker KEY200.4 Manual

Bi-amping the KSS369 and KSS365 with the KEY200.4 amplifier
Passive Crossover Points for KSS 3-way Component Systems
Kicker's 3-way component systems are designed to work with the output of almost any factory or
aftermarket radio/amplifier. The balanced speaker system will provide full range output when using only
the crossovers included with the set.
The passive crossover points for the 3-way components that have been set to give you the best sound
quality with a full range input.
The passive crossover frequencies are as follows:
• Woofer: LPF 1.5kHz (6dB/octave)
• Midrange: BPF 1.33kHz to 4.1kHz (6dB/octave)
• Tweeter: HPF 13.26kHz (6dB/octave)
Note: A high pass crossover is suggested when running a dedicated subwoofer. This will improve Power
handling and performance of the KSS components.
Things to Consider when Bi-amping 3-way speakers with a KEY
The KEY200.4 is a great option for bi-amping a 3-way front stage. The key factors to consider when using
the KEY amplifier in this application are power distribution and time alignment.
1. Power Distribution
To maintain a balanced and dynamic sound, the midbass drivers—which typically require the most
power—should each be powered by their own dedicated channel. Meanwhile, the midrange and
tweeter can share a single channel per side, since they draw less power and don't require as much
amplification.
This setup ensures the midbass is not underpowered, which is critical for maintaining the full-body
impact of your sound system.
