"Learned" a new amp myth today

    The world of amp myths seems to be an endless spring of nonsense. Today a co-worker of mine tried to tell me that adding more speakers makes a rig quieter. The "reasoning" is that each speaker gets less power.
  2. BWAAHAHAHA. Does this person also think bringing home a new girlfriend will make your current wife/girlfriend really happy? :D
    See if light passes straight through their ears. :)

    I was thinking of when I saw Dinosaur Jr how ungodly loud J's 3 Marshall stacks were and image how much louder it would be with a single 12 cabinet.

    If only the myth were true, we'd all be gigging 110's.

    To be fair, this seems ridiculous to us because we already know it's wrong. If I knew nothing about acoustics or electronics at all and I was just a simple guy who just played, never fussing about my gear or rig, I can almost guarantee that I'd buy this on face value.

    I don't know if I'd believe that the amp would be quieter, but If someone said "Yeah if you have a 300 watt amp, there are only so many watts so if you had a 300w 410 and a 600w 810 both cabs would push the same volume because you can't exceed the amount of watts the head has".

    It's not so outlandish that someone would believe that. Not even slightly.

    And yet, clearly there's an efficiency threshold, yes?
    And most of our amps are WAY above that efficiency threshold.
    It gets more complicated with 'modern' amps that can drive X watts into 8 Ohms and (nearly) 2X watts into 4.

    But if I'm driving a 410 with a 1-watt amp - yeah - I can believe it'll get quieter if I try to drive 2...

    Or is this just more myth? 'cause if it is, I'll sell my 1000W amp and buy a 1W amp - and another 410...

    If the cabs are out of phase ...
    Or placed out of phase
  8. There is a point of diminishing return. Be it 1 watt of power into a large number of speakers or a large amount of power into a small number of speakers. The world is not just black or white, there are a lot more colors to be observed. Even quite a few as human's we can not "see". ;)

    1 watt into two efficient 410's could still be very well louder than one. On the other side inefficient 410's could be quieter.
  9. Then there's those crazy combos with series extension cab wiring.
