Pro audio technicians know that crossover fuses fail at the worst possible moments. These 12-volt, 25-watt glass bulb fuses are designed specifically for Seismic Audio crossover models SACN-151, SACN-152, and SACN-153, providing reliable protection for your active crossover circuits.

When a crossover fuse blows during a live performance, having spare fuses on hand means the difference between a quick fix and a show-stopping failure. These glass bulb fuses protect sensitive crossover components from power surges and overload conditions that can damage expensive circuitry.

Each fuse measures 1 5/8" x 3/8" and handles up to 25 watts at 12 volts, matching the exact specifications required by compatible Seismic Audio crossovers. The glass construction allows visual inspection of the filament, making it easy to identify blown fuses during troubleshooting.

Sound engineers, live sound technicians, and venue operators rely on these replacement fuses to maintain their PA system crossovers. Whether you're running sound for a church service, corporate event, or live music venue, keeping spare crossover fuses in your toolkit prevents costly downtime when equipment protection circuits activate.

This three-pack ensures you have backup fuses when you need them most. No special installation tools required — simply remove the blown fuse and replace with a new one. Ships fast with Seismic Audio's reliable service, backed by our standard warranty coverage.

Technical Specifications

Frequently Asked Questions

Which Seismic Audio crossovers use these bulb fuses?

These fuses are specifically designed for Seismic Audio crossover models SACN-151, SACN-152, and SACN-153. The 12-volt, 25-watt rating matches the exact protection requirements for these active crossover units. Check your crossover model number before ordering to ensure compatibility.

How do I know when a crossover fuse needs replacement?

A blown fuse will show a broken filament visible through the glass tube, and your crossover will stop passing signal to the affected frequency band. You may notice missing highs, mids, or lows in your PA system output. Always power down your system before inspecting or replacing fuses.

Why do crossover fuses blow and how can I prevent it?

Crossover fuses typically blow due to power surges, speaker impedance mismatches, or overdriving the crossover beyond its rated capacity. Ensure your speakers match the crossover's impedance rating and avoid pushing input levels into distortion. Keep spare fuses on hand since they can fail during critical moments.

Can I use a different wattage fuse if I don't have the exact replacement?

Never substitute a higher wattage fuse, as this can allow damaging current levels to reach sensitive crossover components. Using a lower wattage fuse may cause premature failure under normal operating conditions. Always use the exact 12-volt, 25-watt specification for proper circuit protection.

How many spare fuses should I keep in my equipment case?

Most professional technicians keep at least 3-6 spare fuses in their repair kit, which is why this three-pack provides a good starting inventory. For touring or critical applications, consider ordering multiple three-packs to ensure you never run out during important events or extended road work.
