Why this tweeter
Neodymium gives the same motor force in a fraction of the volume. That is how a tweeter 88 mm across and 68 mm deep still handles 150 W RMS at 0.45 kg.
A bullet tweeter is built for pressure. At 107 dB it stays over the midrange and the sub on very few watts, which is exactly what you want on a loud front stage.
25.4 mm of KCCAW winding on a 25 mm throat. Light wire means the coil follows the signal, and takes the heat of 150 W RMS without compressing.
The price is for one tweeter. Buy two for a front stage, or four, six and up for an SPL wall, without paying for pairs you do not need.

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. Two of these 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.
