These 3-way, 2nd-order (12 dB/octave) crossovers were designed with a 3 octave spread between crossover points. Dayton Audio metallized polyester film capacitors are used in the critical midrange and tweeter signal paths. 18 gauge tweeter and midrange inductors, and 20 gauge woofer inductors are used to keep DC resistance to a minimum. A unique design feature of the low-pass section allows for the use of 4 or 8 ohm subwoofers, perfect for building a multi woofer system. The midrange and high-pass sections are rated for an 8 ohm load. All components are glued or fastened down to eliminate buzzing and vibrations. The high quality blue PC board uses a back plate for added rigidity and eyelet holes for easy mounting. Available in a variety of crossover points. 300W power handling. Board measures: 11-3/8" W x 4-3/8" H x 2" D. Terminals are 0.205".
