    Hello,
    I recently purchased a sound level meter to check my speaker levels. My speaker manual says to set the scale to 70 db and set all speakers to 75 db. This caused me to dial my speakers back -3.5. My question is why 75 db and not 80 db for example? Is there a reason 75 db is used? Also, should I attempt to set my sub at the same 75 db level? How do you set your sub level?

    The test tones output by the receiver should equate to reference level when at an indicated 75 db on the SPL meter.

    If you want a flat response from your speakers you will need to set the sub at the same level although some people like to set their sub louder than the rest of the speakers.

    I am not one of them.

    As Ian says, all speakers including your sub should be set to the same volume level to start with although obviously you can tweak that afterwards to suit your own taste and listening environment.

    The idea of setting all speakers to the 75dB level help imply a link between the numbers on the volume display of your amplifier and the actual volume (so 85dB (or -15dB depending on how your display works) actually relates to an approximate volume in your room of about 85dB). Obviously this isn't strictly true as there are plenty of other factors such as the actual media being used and how your speakers interact with your room. :)
