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

db growth chart:
85db @ 1 watt
88db @ 2 watts
91db @ 4 watts
94db @ 8 watts
97db @ 16 watts
100db @ 32 watts
103db @ 64 watts
106db @ 128 watts
109db @ 256 watts
112db @ 512 watts

You need to double wattage to gain 3 db
To get a perceived doubling in volume, you need a 10db gain
THX = 110db
THX ultra = 112db
Jet planes, rock concerts and jack hammers usually don't break 130db to 140db or so.
170db could cause a lot more than deafness (brain damage?)
NONE of us own stereos capable of 140db, let alone 170db!
