当然是标称的比较好，不过实测差距不能说很大。
灵敏度实测大概88db，20的时候到了3.27欧姆。
这是2010年时候john atkinson在天书文章里的一段话：
I estimated the G1Giya's voltage sensitivity as 88dB(B)/2.83V/m, which is 3dB lower than the specified 91dB. The G1 is specified as having a 6 ohm nominal impedance, with a minimum value of 4 ohms. Fig.1 shows that the minimum impedance magnitude is a little lower than specified, at 3.27 ohms at 20Hz and 3.35 ohms at 60Hz, though the electrical phase angle tends to be large only when the impedance is also high, thus mitigating its effect. While there is a fairly demanding combination of 5 ohms and –42° at 15Hz, there will be no musical energy in this region to lead to drive problems. The impedance remains above 8 ohms throughout the midrange and above 12 ohms in the treble, which might make the G1Giya sound a little uptilted when driven by a tube amplifier having a typically high source impedance.
