The Klipsch DNA, an advanced Tractrix horn. This patented and exclusive horn technology delivers the power, detail and emotion of the live music experience with the cleanest, most natural sound possible. The horn's increased external dimensions allow control of dispersion over a wider range of frequencies, resulting in improved high frequency dispersion and a more precise soundstage. The rear Tractrix port is perfectly matched to the cabinet and woofers, ensuring ideal airflow with minimal distortion or turbulence even at the lowest frequencies. High-quality housing design. Reinforced 3/4" MDF construction with a completely new bracing design reduces cabinet vibration for less audible vibration and improved sound accuracy. The MDF cabinet is finished with a scratch-resistant wood-grain vinyl veneer.
