So you have a peak ouput at - 10dB. You are correct, that's around 45 watts, which means a dB gain of about 16dB. If your speaker sensitivity is 90dB, you would be listening at a peak level of roughly 106dB. Yep, that's loud! Now if your speakers had a sensitivity of 83dB, then your peak listening level is only 99dB. Now factor in the dynamic range. Let's assume you are listening to a well recorded, not overly compressed CD. CDs are routinely recorded with a dynamic range of 20dB peak to mean. Meaning that the average level can be 20dB below the peak level. Applying that to the 90dB sensitivity figures means that your average listetning level is about 70dB and is using .45 watts at that point.
Does that make sense?
