So I was wondering if someone could help me understand about amp power etc. So originally I had always (maybe foolishly) assumed that a 100w amp had twice the out put of a 50w. After reading about this is would seem to suggest that this is correct in terms of acoustic power, an amp with twice the watch would create 3db more than the other amp with half the wattage therefore doubling the acoustic power. Reading on it suggests that because hearing is based on sound pressure you actually need 6db of volume to create double the sound pressure? Therefore if you wanted an amp twice as loud as your 50w you would need a 200w Now on reading other bits and bobs it suggests that to create twice the volume you need 10x the wattage... So to get an amp twice as loud as your 50w you would need a 500w amp... I normally use a little 5w amp and was thinking about getting a 12w number but if it's only going to have 20% or so power then I'll re think. If someone could help me understand I would be very appreciative!
