DS18 PRO-TWN3 2.5" tweeter

The DS18 PRO-TWN3 is a 2.5-inch high-compression neodymium tweeter built for car-audio enthusiasts who want maximum high-frequency output. Its square 63 mm aluminium frame allows tight side-by-side mounting for a uniform wall of tweeters. Rated at 107 dB sensitivity, it delivers crisp, bright highs up to 20 kHz with authority.

Upgrade from factory tweeters

Factory dome tweeters typically lack the power handling and sensitivity needed for competition-level SPL. This unit handles 50 W AES continuous and 200 W peak, so it stays clean when driven hard. The jump is worth it when you are adding amplification and need a tweeter that will not compress or fail at high output.

4 Ω load with passive crossover

The 4 Ω nominal impedance and included 2.2 µF capacitor set a 2 kHz high-pass point, limiting low-frequency excursion. Without an active crossover you cannot adjust slope or crossover frequency. The Kapton former and CCAW voice coil handle heat well, but the 1.6 kHz lower limit means midrange duties must be covered by separate drivers.

Questions about this item

What cutout diameter and mounting depth does the 2.5-inch tweeter need?

The front-mount baffle cutout is 2.12 inches and the mounting depth is 1.32 inches.

How do I connect the included 2.2 uF filter and where do I set the crossover?

Wire the 2.2 uF capacitor in series with the positive lead and set the high-pass crossover at 2 KHz.

When should I replace the PEN diaphragm or the 1-inch CCAW voice coil?

Replace them if output drops, distortion appears at high volume, or the voice coil rubs magnetically.
