What really makes a Amp loud?

Re: What really makes a Amp loud?

Sorry, I'm not following/understanding????? Please clarify.
Did you follow that the increase of 3 db occurs when the number of identical sources is doubled? i.e. the progression is 1,2,4,8,16. This is verified by the chart in your second link. Note when x=2, y=3; x=4, y=6; x=8, y=9

I think this discussion is not taking into account that speakers are a load, not a power source. So doubling speakers is not doubling power. Doubling power results in a 3db increase, not doubling the resistance/impedance load. Whether the speakers are wired in parallel or series will factor into the result here.

What you get with more speakers is greater distance projection because you are moving a larger column of air, so frequencies survive a greater distance before being absorbed. This is what line arrays are all about. They technically aren't louder, they just travel farther. Because the sound travels farther, people have the perception that it's louder, but it really isn't.

.....yes, I've known this for over thirty years.
I was reffering to the following. [ Different calculator ]
Adding Equal Sound Pressure Levels Calculator

Then, why in the previous calculation did you add 3 db 3 times, when it should have been 2? i.e the base db plus 3db (1 unit to two), then this sum plus 3db (two units to four)?
I don't really care to spend the time going into and analyzing a second calculator, especially when I'm beginning to sense that you really just want to be defensive and argumentative.

Facts have been presented and surely everyone will not believe them....human nature. I'm done here.

Not at loud volumes. The ear works most evenly at 98 Db. That's also the dynamic range of CD's. Getting louder than 98 Db the ears response starts to get uneven again.
Loudness is measured in Phons.

Huh, I didn't know that the midrange hump we hear disappears at high volume. Thanks for sharing.

Tubes.. Tubes also go a long way in the quest for loudness.
You want real loud get a Mesa Boogie Coliseum it's 200 watts of pure tube power and it's the loudest damn thing I've ever plugged into. 2 4x12s and I thought the dudes house was gonna cave in.
It hurt, I never wanna play one again.
You want loud you can't beat 100 tube watts thru a 4x12 or a Fender Twin, they are also crazy loud.
I have owned a 200 watt Randall for a metal band but it was nothing compared to my Marshall JCM 900 100 watt. You can't beat tubes for loudness.

havent played through alot of different amps but out of the ones i have..a 1970 ampeg v4 is a beast..really miss that amp

btw.. my old randall RG 100es creams my RH 200.. wattage isnt everything.. even comparing SS to another SS

i do prefer to play the rh 200 at low volumes though as i cant play real loud where im at. RG sounds doesnt sound as good unless you crank it abit IMO

Yes.... It's this:

Wanna make an amp loud? Add a few of these. Your playing gets better also.

Plus this:

Turning the volume knob up all the way seems to me what really makes an amp loud. *shrug* Surprised no one else mentioned that.
