I've heard ppl saying things like "that cab gets a lot louder than THAT cab!" As an example:I'm running an ampeg svt 7pro into a 410HLF.....would it seem to louder if I were going through an svt 810e or 610hlf? Bc from what I hear they're very "loud" cabs. Side Q: Would there be more apparent volume from two 8 ohm 410s than a 4 ohm 810 if I'm using the same head?
