DS18 4" Super Bullet Tweeter - PRO-TWX3 4Ω Titanium Diaphragm, 106dB Sensitivity

DS18 PRO-TWX3 is a 4" super bullet tweeter engineered for clear, high-output highs with a 1.5" aluminum voice coil and a 4-ohm impedance.

The DS18 PRO-TWX3 brings pro-level high-frequency performance into car and pro audio setups. Built with a titanium diaphragm, a 1.5" aluminum voice coil former, and a ferrite motor, this super tweeter is designed to reproduce detailed mids and highs from 3 kHz up to 20 kHz. With AES, program, and peak power ratings that support demanding use, the PRO-TWX3 is suited for installers and enthusiasts who want crisp high-end extension and strong sensitivity in a compact 4" footprint.

How loud and powerful is the PRO-TWX3 compared to stock tweeters?

The PRO-TWX3 is specified for 125W AES (RMS), 250W program, and 500W peak handling, with a sensitivity of 106 dB (1W/1m). Those ratings indicate it can handle much higher input levels than typical factory tweeters while producing louder, clearer high frequencies.

• 125W AES (continuous) handling for sustained use
• 250W program power for common real-world peaks
• 500W peak power for short transients and dynamic passages
• 106 dB sensitivity means efficient output from modest amplifier power

What are the key build and material features that affect sound?

The PRO-TWX3 pairs a titanium diaphragm with a 1.5" aluminum voice coil former (Kapton) and CCAW winding to combine low mass with robust thermal handling. A ferrite magnet and precision motor geometry support transient response and controlled dispersion across the 3–20 kHz band.

• Titanium diaphragm for crisp, detailed high-frequency reproduction
• 1.5" aluminum (Kapton former) voice coil for improved thermal tolerance
• Ferrite magnet and focused motor for consistent performance
• Black aluminum bullet housing for durable mounting and aesthetic integration

How do I integrate the PRO-TWX3 into a system and what crossover is recommended?

DS18 recommends a high-pass crossover at or above 3 kHz to protect the tweeter and ensure proper blending with midrange drivers. Because it is a 4-ohm driver with high sensitivity, use an amplifier or crossover network matched to that impedance and output level for best results.

• Recommended high-pass crossover: 3 kHz or higher
• Nominal impedance: 4 ohms — choose compatible crossovers/amplifiers
• Front mount cutout: 3.62" (92 mm); mounting depth: 2.36" (60 mm)
• Overall diameter: 4" (102 mm) — compact footprint for many installations

Who is this for? The DS18 PRO-TWX3 is aimed at audio enthusiasts, professional installers, and performers who need a compact super tweeter able to deliver high output and detail at elevated volumes. It suits custom car audio projects, professional PA systems seeking enhanced high-frequency extension, and anyone replacing weak factory tweeters with a higher-sensitivity, higher-power option. If you need a rugged, high-sensitivity 4" super tweeter with pro-grade materials and a bold black finish, the PRO-TWX3 is built for that application.
