The P-112 is a high-performance, self-contained two-way loudspeaker featuring a 12-inch woofer and a 1-inch tweeter. The woofer incorporates an optimized voice coil length to increase linear excursion, extending its frequency response while minimizing harmonic distortion and enhancing the driver's dynamic range. The tweeter utilizes PM4 diaphragm technology—a system employing an advanced polymer material never before used in the audio industry—to establish a stronger bond between the dome and the voice coil former. This design enables the driver to perform more reliably during prolonged, high-power operation, resulting in a more natural and authentic sound.
