250 watts per channel in to 8 Ohms with 26.6 db of gain.
26.6 dB..... 10 to the power of (26.6/20) = gain of 21.4
250W into 8 ohms takes 44.7V because ((44.7 squared)/8) = 250
44.7V divided by 21.4 = sensitivity of about 2.1V
.8V sensitivity and puts out 225 watts (tested at closer to 300) onto 8 ohms.
300 watts into ohms takes 49V
49V divided by .8V = gain of 61
20 log 61 = 35.7 dB
