1. Capacitance value
2. Voltage rating
3. Material type
4. Tolerance
5. Temperature coefficient

When considering these specifications, one must evaluate the unique needs of the audio application, as different types of capacitors may offer varying benefits. For instance, polyester capacitors are often recommended for affordability and good performance, while polypropylene capacitors might be ideal for high-end audio systems due to their superior audio fidelity.

1. Capacitance Value:
   Capacitance value determines how much electrical charge the capacitor can store. It is measured in microfarads (µF). The correct capacitance value is essential for ensuring that the crossover effectively filters frequencies. A wrong value can lead to poor sound quality. For example, a typical crossover for a tweeter may require a capacitance value of 2.2 µF, while larger drivers might need higher values.

2. Voltage Rating:
   Voltage rating indicates the maximum voltage the capacitor can handle without failing. It is vital to select a capacitor with a voltage rating higher than the expected maximum voltage in the crossover circuit. Using a capacitor with an insufficient voltage rating can lead to breakdown and failure. Capacitors in most audio applications often have voltage ratings ranging from 50V to over 100V.
