DS18 PRO-TWN4 1" Neodymium Super Tweeter 140W RMS

DS18 PRO-TWN4 is a compact 1-inch neodymium super tweeter built for high-output, crystal-clear high frequencies with 140W RMS and 105 dB sensitivity.

This compact bullet-style super tweeter packs professional-grade materials and engineering into a small footprint so you can add crisp, extended highs to car or custom audio systems without bulky housings. The PRO-TWN4 combines a 1-inch voice coil, a lightweight neodymium magnet for increased efficiency, and a composite polyimide diaphragm to reproduce detailed upper frequencies from 1.5 kHz up to 20 kHz. It ships with a built-in capacitor filter (bass blocker) to protect the driver from low-frequency energy and prolong its life under demanding conditions.

How much power can this tweeter safely handle?

The PRO-TWN4 is rated for 140 watts RMS and 280 watts peak at 4 ohms. That rating gives it headroom for dynamic peaks while the included internal capacitor reduces risk from bass and low-mid content.

• RMS power: 140 W at 4Ω for continuous performance
• Peak power: 280 W for short transient bursts
• Built-in bass blocker for added driver protection
• High 105 dB sensitivity reduces required amplifier output

What does the hardware and build quality include?

DS18 built the PRO-TWN4 with a high-quality aluminum frame and a composite polyimide diaphragm to balance durability with fast, detailed high-frequency response. The neodymium magnet keeps weight low while increasing magnetic flux for improved efficiency.

• Aluminum frame and diaphragm for rigidity and bright highs
• Neodymium magnet for stronger output and lighter weight
• 1" voice coil specifically sized for high-compression super tweeter use
• Compact dimensions: 2.95" overall diameter, 1.87" depth

How will adding these tweeters change my sound system?

Adding PRO-TWN4 super tweeters sharpens the top end and increases perceived detail and air in recordings, making cymbals, vocals, and ambient cues more distinct. Their 105 dB sensitivity means they can achieve loud, clean highs without needing a lot of amplifier power.

• Extended frequency response: 1.5 kHz–20 kHz for clear treble detail
• High sensitivity improves loudness with modest amps
• Bullet-style dust cap helps highs cut through road noise and bass
• Versatile mounting fits custom and OEM locations with 2.04" cutout

What installation and replacement parts should I know about?

The tweeter is supplied as a single unit with a protective bass blocker; dimensions and mounting specs make it straightforward for flush or surface installs. DS18 offers a replacement diaphragm (PRO-TWN4VC) if service is needed down the line.

• Front mount baffle cutout: 2.04"; mounting depth: 1.16"
• Included capacitor (bass blocker) for low-frequency protection
• Replacement diaphragm available: PRO-TWN4VC
• Package quantity: 1 tweeter per box for single-channel upgrades

Who is this for: The DS18 PRO-TWN4 is aimed at audio enthusiasts and installers who want a high-output super tweeter to add clarity and sparkle to car stereos, custom audio systems, or focused high-frequency arrays. If you need a compact, lightweight driver with professional power handling and easy integration, the PRO-TWN4 provides a reliable, high-sensitivity option that pairs well with a range of amplifiers and crossovers.
