Pros & Cons
👍 Pros
- Features a 3-inch pure titanium compression diaphragm, ensuring precise and detailed high-frequency reproduction with low distortion.
- Offers a robust 220W continuous program power handling, allowing for high output levels without compromising integrity.
- Provides a wide frequency range of 500Hz - 20kHz, capturing a broad spectrum of critical mid-range and treble frequencies.
- Incorporates a 3-slot optimized geometry phase plug, which contributes to a coherent wave-front and improved clarity.
- Equipped with a ceramic magnet assembly and a copper inductance ring for extended response and controlled voice coil behavior.
👎 Cons
- Requires a 2-inch exit throat for mounting, which means it may not be compatible with all horn types or system configurations.
- The 500Hz minimum frequency might necessitate careful crossover design to integrate smoothly with woofers without gap or overlap.
- Weighing 5.72 kg (12.61 lbs), this driver is relatively heavy, which could add significant weight to portable sound systems or line arrays.
- Specific impedance is 8 ohm, which must be matched with amplifier and crossover output for optimal performance.
- The bolt-on mounting mechanism is secure but may require more effort or specific tools for installation compared to screw-on types.
