H1571 + T25CF001 2way Passive Crossover Design

Seas W15CY-001 and T25CF-001 2-way Design This design uses a single inductor in series with the woofer, with some additional parallel circuitry. The high pass has two capacitors, and film caps would be a good choice there. No box or cabinet is specified.
