Re: SPL [sound pressure level] question
Dale,  
you've got a couple of things confused here. A TEN decibel increase is double the volume. it takes twice the power for an increase of 3 db, you have to increase power 10 times to double the volume. 3db is generally considered an easily noticeable difference, many people have a tough time hearing 1db. Manufacturers all have their own ways of determining speaker ratings, and those specs should be taken with a grain of salt. Also, a 3db difference is more apparent at low volumes than at, say, stage volume. IMO the difference won't be a problem onstage (maybe a SLIGHT decrease on your master) You will only really notice the first time you fire it up --partly because you expect to :>)
