Right so you have to double the wattage to get a 3db increase in volume if you don't double the wattage you don't get a noticable difference in volume. So a 300w amp will sound just as loud as a 400w amp RIGHT? A 400w amp will sound just as loud as a 700w amp right? So if the 300 sounds as loud as the 400 and the 400 sounds as loud as the 700 how come theres a difference between the 300 and the 700. Is it just me or is this a bit strange. Yes yes I know bit of a pointless thread but its bothering me.
