What to Look For Before Buying

Choosing the right horn comes down to your specific audio goals. You must decide if you need to boost vocals or clarify the high end. Focus on sensitivity and power handling first.

Check Frequency and Sensitivity

Look for high sensitivity ratings in decibels. This means the driver will play louder with less power from your amplifier.

Value Power Handling Capabilities

Check the RMS power handling. Avoid focusing on peak power. Ensure your amp matches the driver’s needs to prevent damage.

Rating Material Quality

Material matters for sound. Phenolic works well for warm, clear vocals. Titanium is better if you prefer bright, sharp highs.

Verify Installation and Fitment

Measure your install depth before buying. A powerful driver is useless if it does not fit behind your door panel.

Frequently Asked Questions

What is the difference between a driver and a horn?

The driver is the motor that makes the sound. The horn is the flare that directs that sound toward the listener.

Can I use a car horn for music?

Standard automotive horns are not for music. They are designed for loud, single-tone alerts. Use compression drivers for high-fidelity audio.

What does sensitivity mean in a horn?

Sensitivity measures how efficiently a speaker converts power into volume. A higher number means a louder sound from less energy.

Do I need a crossover for these?

Yes, you should use a crossover. It blocks low frequencies that could blow the delicate diaphragm of a horn driver.

Is phenolic or titanium better?

Phenolic is smoother for vocals. Titanium is sharper and brighter. Choose based on whether you want warm or crisp sound.
