  • Page 7: Introduction

    The L-Vents laminar vented ports reduce turbulence and port noise at high levels to increase LF efciency. The X12 operates from 59 Hz to 20 kHz. The coaxial transducer arrangement and its ellipsoid acoustic design produce a 90° × 60° directivity pattern with a smooth tonal response free of secondary lobes over the entire frequency range.
