F2A Crossover

An F2A crossover is a specific model of a 2-way speaker crossover that acts as a frequency divider for a speaker system, separating an audio signal into bass and treble frequencies to send them to the correct driver. This improves sound quality by sending low frequencies to a woofer and high frequencies to a tweeter. The "F2A" designation is a model number, and these units are often described as having a maximum power rating, an impedance range, and a specific crossover frequency point.
