Installation frame with spring suspension

摘要

The tweeter is suspended in a housing by several springs and is thus only indirectly coupled to the loud speaker housing. The frame may be plastic or metal and square or round. Its outer diameter is at least 170 mm and its inner diameter is at least 120 mm. The frame has at least three sunk bores for fastening with sunken head screws. The springs are at an angle of 90 deg. to the front panel. The spring holders are static or may be movable around a circular rail.
