    Simple question for an amp noob... what is a crossover? I've checked the FAQs and I've only seen crossovers mentioned, but nothing explaining what it is or how it works.

    I typed "define: crossover" into Google (a handy tool), and this is what came up:

    "A component that divides an audio signal into two or more ranges by frequency, sending, for example, low frequencies to one output and high frequencies to another. An active crossover is powered and divides the line-level audio signal prior to amplification. A passive crossover uses no external power supply and may be used either at line level or, more commonly, at speaker level to divide the signal after amplification and send the low frequencies to the woofer and the high frequencies to the tweeter.
