TPI Stacks deliver visceral, high-impact sound that’s as precise as it is powerful - a favourite among elite artists and forward-thinking brands. Project Audio showcased these stacks at a special event for a global luxury flagship, where their performance left a lasting impression. For the store’s permanent installation, our sister company specified TPI’s premium loudspeakers to deliver the same level of quality day-to-day.
