DS18 PRO-TWX2 3.78" Super Bullet Tweeter Pair — 4Ω 240W Peak, 1" Aluminum Voice Coil for High-SPL Clarity

The DS18 PRO-TWX2 is a professional-grade 3.78" super bullet tweeter pair built for clear, high-output treble with a 1" aluminum voice coil and 240W peak power handling.

Designed and engineered in the US, the PRO-TWX2 delivers focused high-frequency detail for pro audio, car shows, and competitive sound systems. These compact bullet-shaped tweeters combine high sensitivity and durable materials so they reproduce shimmering highs without distortion when crossed over correctly. The pair ships ready for installation and is built to tolerate demanding use thanks to ferrite magnets, a Kapton former, and an anodized aluminum body.

How loud and powerful are these tweeters?

The PRO-TWX2 is built for high SPL environments: a 103.5 dB sensitivity rating and 240W peak power handling let them sing above complex mixes. With a 4 ohm nominal impedance they pair well with powerful amplifiers and pro crossovers to preserve clarity at high volumes.

• Peak power handling: 240W (pair-rated per speaker specs)
• Program power: 120W and AES-rated 60W
• Sensitivity: 103.5 dB (1W/1m) for efficient output
• Nominal impedance: 4 ohm for standard pro installations

What frequency range and crossover should I use?

These tweeters cover extended highs from roughly 3.5 kHz up to 20 kHz, making them ideal for crisp treble presence and air. DS18 recommends a high-pass crossover at about 3.5 kHz to protect the driver and ensure smooth integration with midrange or full-range speakers.

• Frequency response: 3.5–20 kHz for clear high-end detail
• Recommended hi-pass crossover: 3.5 kHz to prevent low-frequency overload
• Use alongside midrange drivers or component systems for balanced sound

What materials and build details make these tweeters reliable?

The PRO-TWX2 uses a 1" aluminum voice coil wound with CCAW on a Kapton former, an aluminum diaphragm and bullet, plus a ferrite magnet and aluminum body to withstand heavy use. These choices improve heat dissipation and mechanical stability, while allowing quick serviceability like voice-coil swaps when needed.

• Voice coil: 1" aluminum (25.4 mm) with CCAW winding
• Former: Kapton for thermal and mechanical durability
• Diaphragm and bullet: aluminum for crisp transient response
• Magnet material: ferrite; body: anodized aluminum

How do I mount and measure these tweeters for my system?

The PRO-TWX2 is compact yet substantial: a 3.78" overall diameter and roughly 2.78" depth make it easy to fit into custom pods or aftermarket openings. The recommended front baffle cutout is 2.83" and the mounting depth is listed at 2.56", helping you plan clearances and enclosure layouts.

• Overall diameter: 3.78" (96 mm)
• Front mount baffle cutout: 2.83" (72 mm)
• Mounting depth: 2.56" (65 mm); overall depth: 2.78" (70.5 mm)
• Motor diameter: 2.76" (70 mm) for installation reference

Who is this for? The DS18 PRO-TWX2 pair is aimed at car audio enthusiasts, pro-audio installers, and competitive sound system builders who need compact, high-output tweeters for extreme-high-frequency clarity. If you’re upgrading a show vehicle, building a custom speaker pod, or assembling a pro rig that demands high sensitivity and rugged construction, these tweeters offer a serviceable, high-performance option.
