The 3 cm (1") dome tweeter is made of aluminum for both hardness and responsiveness, uses a neodymium magnet. It delivers sound that links the medium and high ranges with natural smoothness and transparency. Firmly integrating the diaphragm and voice coil and using a thick surround material increases the sound density and resolution in the high range. With a heavy aluminum diecast tweeter plate that minimizes unwanted resonances and an extremely fine mesh grill that provides ideal sound dissemination, it faithfully reproduces dense sound atmospheres and nuances from high resolution sound source.

The design of the cabinet is of course extremely important if the aim is to create a speaker with superior reproduction capabilities. The goal was to reduce standing waves to ensure highest accuracy, as well as to provide a full, three-dimensional sound with an awesome feeling of depth. The solution was to design a cabinet with non-parallel surfaces. Another important point is the three-way mitered construction of the cabinet joints, achieved thanks to Yamaha's excellence in woodworking. This technique ensures extremely tight joints so the entire cabinet behaves as a single unit, providing tight, powerful and accurate bass reproduction.

A diecast aluminum tweeter plate isolates the tweeter from cabinet vibration and provides a solid attachment for the tweeter unit. This prevents incidental movement, helping to ensure that the high range sound is clear and transparent, with no coloration.
