Power Star 69.3

3-way Triax system

3-way Triax system

The 3-way Triax system of the Power Star range displays a maximum music power rating of 480 watts and acoustic pressure of 91 dB. These excellent values are achieved with a 150 x 230 mm bass speaker comprising a polypropylene membrane as well as a titanium-coated polycarbonate 50 mm midrange driver and a 13 mm tweeter. The centering and the magnetic field of the structure, which is positioned in a sturdy steel basket with additional voice coil ventilation, has been optimized using the Klippel measuring procedure. This results in a very dynamic and, at the same time, very authentic sound. The 3-way Triax system has an exclusive and stylish appearance with the sturdy cover grill featuring the aluminium diamond-cut logo and the attractive Mac Audio design magnetic field protection ring.
