Polypropylene Capacitors

Our audio-grade Polypropylene Capacitors are built to tight tolerances and constructed using premium materials, including pure polypropylene film and oxygen-free copper leads that have been pre-tinned for easy soldering. Featuring incredibly low ESR (Equivalent Series Resistance) they are designed and tested for audio signal integrity. These name brand capacitors are performance proven and trusted around the world by top speaker manufacturers in their high-fidelity speaker crossovers.

Whether you're designing a first-order crossover or a complex multi-way system, these audio capacitors provide the clarity, detail, and reliability needed for critical listening environments. Use them with confidence in any part of your crossover network to achieve a more open, natural, and dynamic sound.
