The sealedenclosure and the wide-bandwidth single-reflex bandpass are the least efficient designs.
密闭箱和宽带单反射带通是效率最差的设计。

It is generally accepted that an optimized sealedenclosure exhibits the best transient response characteristics.
通常人们接受的说法是最优化的密闭箱能表现出最好的瞬态反应特性。

Single-Reflex bandpass designs can also have good transient characteristics if their bandwidth is fairly narrow, but again, not as good as an optimized sealedenclosure.
