Why this driver
The 16 oz motor keeps the voice coil under control at high level, session after session. Sensitivity stays at 113 dB and it takes 250 W RMS.
Sensitivity is what makes a horn loud. At 113 dB this driver stays above the midrange and the sub without asking for huge power.
The horn comes in the box, already matched to the 25 mm (1") throat. No guessing about flare or coupling: it arrives as one working assembly.
The coil measures 34.4 mm / 1.35" and is wound in CCAW (aluminium). That is the part that turns 250 W RMS into pressure and then has to survive it.

Complete the system
Before you install it
- It always needs a crossover. Never full range. A compression driver wired straight to the amplifier does not survive. Use a crossover, or at the very least a capacitor in series.
- Do not cross below 1.5 kHz. 1.5 kHz is the lowest frequency this driver is rated for. Going under it, at any power, is the fastest way to tear the diaphragm.
- Do not go below 4 ohm per channel. 4 ohm is the minimum load. Two drivers in parallel on one channel give 2 ohm: most amplifiers will heat up or go into protection.
- Aim it, and set the gain low. A horn is directional, so point it at the listener; then bring the level up slowly. Clipping kills compression drivers far more often than power does.
