If you are comparing two center speakers (one small and the other large) with the following specs:
small speaker (sensitivity: 89 db, impedance: 8 ohms )
large speaker (sensitivity: 90 db, impedance: 8 ohms )
What is the difference is sound dB between the two? I'm trying to compare both of these (have them hooked up to a receiver). If I have the the volume on the receiver set to a certain level (let's say 60dB), and I play back something, the larger speaker sounds louder (and can hear more details). To get the smaller speaker up to the level of the larger one, I have to increase the volume level on the receiver (I just increase it maybe by 5-10 decibels). I would like to know what the actual level I should be increasing it to, to get the most accurate picture, rather than just guessing. I'm sure there's a hard and fast rule about this, or calculation to use
thanks
