Hi Folks,

I am feeling a little practically confused....

I have noticed lots of speakers with different dB/spl ratings, and wondered if someone could help me understand them a little more?

What I am actually interested in is how much more 'audible' volume a 92dB speaker would give for the same given wattage compared to a 89dB speaker? Or let me rephrase it another way...

If I have an 89dB speaker, how many more watts of power would that require to achieve the same audible level as a 92dB speaker?

Although I am very familiar with sound and how it works, since I am a sound engineer, this is something I've always struggled to get my head around!

Regards
G!
