Dayton Audio XO3W-500/4K is a three-way speaker crossover for home speaker builders and multi-driver projects. It divides the signal into low, mid, and high-frequency sections at 500 Hz and 4,000 Hz.
The second-order network slopes at 12 dB per octave and places the crossover points three octaves apart. Metallized polyester film capacitors handle the midrange and tweeter signal paths. The tweeter and midrange coils use 18-gauge wire, while the woofer coil uses 20-gauge wire. The low-pass section supports either 4-ohm or 8-ohm woofers.
