150 watt RMS.
The top end that cuts through.

Why this tweeter
A bullet tweeter is not a soft dome. At 114 dB it turns a few watts into pressure, and it stays audible over an SPL system that is already playing hard.
1.7" / 44 mm of CCAW aluminium wire. A large coil takes 150 W RMS continuously and pushes the heat out into the 20 Oz motor instead of cooking itself.
The horn concentrates the output forward instead of scattering it. That is where the efficiency comes from, and why it is aimed at the listener, not at the roof.
160 × 120 mm overall, 95 mm deep, 2 kg. A-pillar, dash or kick panel: it goes on the surface, not inside a door.

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 tweeters in parallel on one channel give 2 ohm: most amplifiers will heat up or go into protection.
- 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.
