The cabinet uses a two-inch-thick baffle, which consists of a MDF outer layer with a special asphalt-like compound between it and its front cabinet enclosure. In addition, the cabinet itself is a labor-intense effort to eliminate any resonances that would contaminate the purity of the audio signal. Lastly, the speaker enclosure is composed of nine-layer laminate, curve-stressed MDF walls with seven interlocking full-sized internal braces. As for connection options, the 7T has two sets of high-end five-way binding posts, capable of accepting all types of speaker cable as well as allowing you bi-wire or bi-amp the 7T. All of these factors give the 7T a reported frequency response of 28Hz to 25kHz plus or minus two dB, with negative six dB at 23Hz. The 7T's sensitivity is 89dB for 2.83 volts at one meter on axis. Impedance is four ohms nominal and three ohms minimum. 这段话翻译成中文是什么意思?急求教 |
