Kenwood eXcelon 4-Channel Power Amplifier, Model X450-4

Excelon Performance & Quality - eXcelon products incorporate the latest technologies and deliver the highest sonic performance.  From advanced audio tuning capabilities, crossover and equalizer systems, high voltage preouts and two-year warranty, eXcelon represents the very best product available.

Assymetrical 4-Ch Design - A unique staggered power supply design allows the amplifier to run in 4-channel mode for demanding front and rear speakers or 3-channel mode for front speakers plus enough power to drive a subwoofer at 300W RMS bridged simultaneously.

Variable High-Pass Filter - Filters low frequencies out of the music and passes only signals above a certain frequency (called the cut-off frequency) to mid and high range speakers.

Variable Low-Pass Filter - Filters high frequencies out of the music and improves efficiency and sound quality by allowing only the low frequencies to pass to the subwoofer.

Variable Bass Boost - Adjust the fixed bass boost frequency (40Hz) to maximize natural bass performance.
