The high-frequency section has been completely reevaluated in the Titan X12, for both coverage and sound quality. Firstly the HF unit has been strengthened via a rear aluminium cover, which improves heat dissipation for high-pressure audio and prolonged time periods. Wharfedale Pro engineers have paid particular attention to the acoustic properties of the new HF to ensure a much smoother sound, especially at high output. While the high frequencies are clear and detailed, a new custom phase plug has been formed for dimensional stability and accurate phase coherence. Combined with the hybrid symmetry horn, the full range sound of Titan X12 is heard loud and clear to everyone in the crowd.
