Actually, if your speakers' sensitivity are 85db/1W/1M, then, of course with 1 watt of power at 1meter, you'r SPL will be 85db. Since you'd need to double your power to increase your SPL by 3db, you'd need 536,870,912 watts to double your volume to 172db. So, if your SPL was X at your listening distance with 200w,and you now raised your power by 50% you're only raising your SPL by 1.5db. Not very much.
a Power vs Volume Question
Hell,
I just replaced my old 200w power amplifier with a new 300w amp. by my surprise, with all things left the same, including the volume setting, the output read by my spl meter was the same between the two amps. isn't the 300w amp supposed to be louder at the same volume setting?
please post your thoughts.
thank you
