HIGH PASS crossover with a 4k Hz crossover point and 18dB per octave slope. Handles 300 watts continuously and 600 watts peak. All components are mounted on a PC board with mounting holes in all 4 corners. No wires attached. You will need to solder wires to this crossover. This is a much higher quality crossover than most others because the NORM is to have a 6dB or 12 dB per octave slope and this has 18. This provides MUCH more protection for any horn driver. 4.25" x 3.5" x 1.5".
