150 watt RMS.
All the top end, half the size.
A neodymium bullet tweeter: 114 dB sensitivity, a 32.4 mm voice coil and 150 W RMS in a body only 100 mm across and 47 mm deep, weighing 0.5 kg. The neodymium motor is what makes it small without giving up output. Sold as a pair.

Why this tweeter
Neodymium gives the same motor force in a fraction of the volume. That is how a tweeter 100 mm across and 47 mm deep still does 114 dB and 150 W RMS.
A bullet tweeter is built for pressure, not politeness. At 114 dB it stays clearly on top of the midrange and the sub, on very few watts.
100 mm overall, 47 mm deep, half a kilo. It fits on an A-pillar, on the dash or in a kick panel where a full size bullet simply will not go.
Two tweeters, left and right, from the same production batch. The two sides of the car sound the same, which is exactly what a front stage needs.

Complete the system
Before you install it
- Never connect it straight to the amplifier. A bullet tweeter always needs a crossover, or at the very least a capacitor in series. Full range on a tweeter destroys the voice coil in seconds.
- Cross it high, not low. This is a super tweeter: it plays the top of the range and nothing else. The mid-bass belongs to the midrange, the bass to the subwoofer.
- Do not go below 4 ohm per channel. The pair in parallel on one channel gives 2 ohm: most amplifiers will heat up or go into protection. One tweeter per channel is the safe way.
- Aim it, and set the gain low. The horn is directional, so point it at the listener; then bring the level up slowly. Clipping kills tweeters far more often than power does.
