A3t is 64 Audio’s 3 driver custom stage monitor. With A3t 64 Audio's Tia technology is available at a new lower price point, along with LID and patented Apex and 3Dfit tech. The goal with A3t was simple: make a reference monitor that rivals products more than 5x its price, this simple yet powerful arrangement of balanced armature drivers and crossover components achieves that perfectly. This is a perfect tool for any audio engineer or musician looking for a neutral, balanced and musical reference monitor for live and recorded performance.
