DS18 GTX1 1" Titanium Neodymium Super Bullet Tweeter 4Ω

DS18 GTX1 is a high-output 1" titanium-diaphragm neodymium super tweeter built for clear, extended highs at professional power levels.

Engineered for installers, audiophiles, and pro-audio outfits, the GTX1 combines a lightweight 1" titanium voice coil, a focused bullet dust cap and a neodymium magnet to reproduce crisp frequencies from 3 kHz to 20 kHz. The die-cast aluminum housing keeps the tweeter rigid and cool, while the included mesh grille protects the driver without sacrificing presence. With a 120W RMS rating (240W peak) and 98 dB sensitivity at 4 ohms, this single tweeter is designed to add sparkle and definition where stock systems fall short.

How will the GTX1 change the clarity of my system?

The GTX1 raises high-frequency detail so cymbals, vocal sibilance, and acoustic overtones stand out without sounding thin. Its titanium diaphragm responds quickly to transients, improving perceived resolution and air in the upper register.

• 1" (25 mm) titanium voice coil for fast transient response
• Frequency range 3 kHz–20 kHz for extended highs
• 98 dB sensitivity for efficient sound output
• Die-cast aluminum frame reduces resonance and coloration

Will it handle loud levels and real-world use?

Yes — the GTX1 is rated at 120 watts RMS with 240 watts peak handling, making it suitable for both loud consumer builds and pro installations. The neodymium magnet provides strong motor force in a compact package so the tweeter stays controlled at high SPLs.

• 120W RMS / 240W peak power ratings at 4 ohms
• Built-in capacitor filter for basic protection and smoothing
• Robust mesh grille and bullet cover protect the voice coil
• Compact mounting depth fits tight installations (1.46" mounting depth)

How do I install the GTX1 and what physical measurements matter?

Mounting is straightforward for most speaker pods, door panels, or custom enclosures. Measure mounting depth and cutout diameter before you begin to ensure a flush, secure fit.

• Overall depth: 1.96"; mounting depth: 1.46"
• Overall width with bezel: 2.95"; required cutout diameter: 2.26"
• Single-piece package — unit sold individually for flexible placement
• Includes a protective mesh grille and bullet-style dust cap

What sonic character should I expect from the GTX1?

Expect a bright, articulate top end with tight focus rather than excessive harshness when crossed in properly. The aluminum frame and titanium diaphragm emphasize clarity and presence, making details pop without masking the midrange.

• Crisp highs that improve imaging and stereo separation
• Controlled output that blends with midrange when crossed correctly
• Designed for pro-audio and vocal-forward mixes
• High-efficiency driver for minimal amplifier demand

Who is this for: installers, car audio enthusiasts, and stage or studio technicians who need a compact, high-efficiency tweeter that can withstand professional power levels. If you want to upgrade a factory system, add crisp air to a component array, or outfit live monitors with a robust high-frequency driver, the DS18 GTX1 delivers extended top-end clarity, reliable power handling, and durable construction in a single, easy-to-install tweeter.
