Crossover PCB layout for Paul Carmody's Speedster speakers. Designed with V-cut stackable boards for high and low-pass circuits.
The layout was designed for the following components. Extra pads have been added to allow the use of physically smaller capacitors. Additional pins have been added to X1 and X2 to support the use of through-hole quick disconnects.
