Frequently Asked Questions - PRO-TWN1 DS18

What is the recommended crossover frequency for the DS18 PRO-TWN1?

The recommended crossover frequency is 2,500 Hz or higher. Use a 12 dB/octave or 24 dB/octave crossover to protect the tweeter from damaging low frequencies.

Can I install this tweeter in a marine environment?

Yes, the PRO-TWN1 is designed for marine and outdoor use. Its titanium diaphragm and corrosion-resistant hardware make it suitable for damp environments, but avoid direct water spray on the terminals.

What is the difference between RMS and peak power handling?

RMS power is the continuous power the tweeter can handle safely, 100 watts. Peak power is short bursts, 200 watts. To prevent distortion and damage, it's best to match the amplifier output to the RMS rating.

How do I connect the PRO-TWN1 to my amplifier?

Connect the positive terminal to the amplifier's positive output and the negative to negative. Ensure the amplifier is off during wiring. Use appropriate gauge wire and secure connections.

Does the tweeter come with mounting accessories?

Yes, the package includes a mounting bracket, screws, and wire terminals. You may need additional adapters for specific installations.

Can I use this tweeter without a crossover?

It is not recommended. A crossover blocks low frequencies and prevents distortion and possible damage. Always use a passive or active crossover set to at least 2,500 Hz.

What is the sensitivity rating and why does it matter?

The sensitivity is 105 dB (1W/1m), meaning it produces 105 dB of sound pressure with 1 watt at 1 meter. Higher sensitivity means the tweeter plays louder with less power, making it very efficient.

How do I clean the tweeter diaphragm?

Use a soft brush or compressed air to remove dust. Never touch the titanium diaphragm with fingers, as oils can damage it. Wipe the outside with a dry cloth only.

Is the DS18 PRO-TWN1 suitable for use in a 3-way system?

Yes, it can be used as the high-frequency driver in a 3-way system, with a midrange driver handling frequencies below 2,500 Hz. The tweeter reproduces the highs clearly.

What type of amplifier should I use with this tweeter?

Use a high-quality amplifier that delivers clean power within the tweeter's RMS rating. An amplifier with 50-150 watts RMS per channel is sufficient, and it should have a built-in or external crossover for high-pass filtering.
