Sunday here at AXPONA 2025 audiophile / high-end audio show delivered more excitement as the final day began for music lovers. Registration and ticket sales open at 9 AM and once again today there were various informative and enlightening seminars. Once again the Master Class Theater Sessions provided knowledgeable insights from expertise within the audio industry. For car audio enthusiasts, IASCA (International Auto Sound Challenge Association), which is a new addition for 2025 to AXPONA, showcased high-performance mobile audio systems. Sound quality is the goal, though some car audio systems do reach very loud volume levels (high SPL). Of course, we can't forget the Ear Gear Experience for those who love their music via a wide range of headphones, in-ear monitors (IEM), and personal audio gear from top brands.
