Every aspect of construction has been thoroughly thought out and examined from multiple angles. Construction requires an incredible amount of focus and dexterity, but even more important is discipline.
Most of our tools and jigs have been custom CNC made for us out of special materials in order to assure the absolute maximum product consistency. Because of this fanatical attention to detail, we are confident that no mass market speakers can approach our level of product quality assurance and consistency.
