| 铝带单元质量非常轻，振动非常灵敏，散动与停止时的惯性作用低，所以速度反应非常快。不过，铝带由于非常轻而薄，相对的也相当脆弱。而由于铝带本身是导体，其阻抗非常低，无法直接与扩大机耦合，必须经过一个阻抗匹配器，阻抗匹配器的品质会影响声音表现。还有，由于铝带必须以非常适当的力量张褂，如果力量调整不当就会影响声音表现。此外，铝带本身是延展性金属，自有其金属疲乏的问题，其张力会随着使用时间的增长而变松。 Aluminum strip unit has very light mass, very sensitive vibration, low inertia effect when moving and stopping, so the speed response is very fast. However, aluminium strips are relatively fragile because they are very light and thin. Because the aluminum strip itself is a conductor, its impedance is very low, so it can not be directly coupled with the expander. It must pass through an impedance matcher. The quality of the impedance matcher will affect the sound performance. Also, because the aluminum strip must be tensioned with a very suitable force, if the force is not adjusted properly, the sound performance will be affected. In addition, the aluminium strip itself is ductile metal, which has its own metal fatigue problem, and its tension will become loose with the increase of service time. |
