Origin Technologies
Tri-Linear Configuration® (TLC)
A true 3-way speaker design with the tweeter and midrange mounted together in a pivoting assembly. This allows installers to direct the critical frequencies towards the listening position for improved imaging and vocal clarity.
Multi-Motion Pivoting (MMP®)
Origin's pivoting driver technology allows installers to compensate for speaker placement restrictions and optimise coverage.
Tool-less Installation
Spring-loaded mounting clips distribute weight evenly across the mounting surface, reducing vibration transfer and speeding up installation.
